     BACKGROUND 
     Electrical wall boxes are well known. A typical electrical wall box includes a housing that is installed within a wall. An electrical wall box is typically configured to receive at least one electrical device, such as a switch or a receptacle, for example. A typical electrical wall box is also configured to receive a wall plate. The wall plate may be adapted to cover a yoke plate and/or escutcheon of the electrical devices mounted within the wall box. The wall plate may be configured to be attached to the electrical device with or without fasteners. 
     An electrical wall box may be configured to receive a single electrical device or multiple electrical devices. An electrical wall box that is configured to receive multiple electrical devices may be referred to as a multi-gang wall box. Different types of electrical devices, e.g., devices of varying size, may be installed in a multi-gang wall box. Different electrical devices may have different mounting requirements, such as different fastener locations and/or sizes, for example. And, though some electrical devices may be installed in a single wall box with other types of electrical devices, certain electrical devices may not be installable in the same wall box with other types of electrical devices. Furthermore, multiple wall boxes may be installed in close proximity to each other, e.g., directly next to each other. 
     A typical wall box installation tool includes a template used for locating a wall box. Typical wall box installation tools provide for the installation of a single multi-gang wall box (e.g., a two- to four-gang wall box), but do not allow for the installation of non-standard wall boxes as well as locating and aligning multiple adjacent wall boxes. 
     SUMMARY 
     As described herein, a wall box installation tool may facilitate the installation of one or more wall boxes for mounting electrical devices to a wall. The wall box installation tool may be configured to aide in the marking and/or drilling of pilot holes required for installing the wall boxes. The wall box installation tool may be used to install one or more multi-gang wall boxes that have either standard or non-standard spacing between gangs. The wall box installation tool may help with achieving the appropriate spacing between and alignment of adjacent wall boxes. The wall box installation tool may be configurable to allow for the installation of wall boxes for electrical devices having different sizes and/or configurations, for different numbers of electrical devices (e.g., different number of gangs), and/or for different spacings between electrical devices and/or other wall boxes. 
     The wall box installation tool may include a template body and a template card. The template body may include a front surface, a guide ring that extends from a rear surface of the template body, and a plurality of bores that extend through the template body from the front surface to the rear surface. The guide ring may be configured to be installed within a pre-drilled hole in a wall. The guide ring may be configured to position the wall box installation tool within a wall. 
     The template card may be associated with an electrical device configuration of the electrical devices that may be mounted to the wall box. The template card may have a plurality of holes therethrough. When the template card is installed on the front surface of the template body, a subset of the bores in the template body are accessible via the holes of the template card. The template card may be removed from the template body and another template card may be installed on the front surface of the template body. The second template card may have a plurality of holes in different locations than the holes of the first template card, such that a different subset of the bores may be accessible via the holes of the second template card. A number of the plurality of holes of the template card may be less than a number of the plurality of bores of the template body. 
     The second template card may be held against the front surface of the template body and may be moved on the template body from a first position associated with a first electrical device configuration to a second position associated with a second electrical device configuration. For example, the template card may be slid along the front surface of the template body between the first and second positions. A first subset of the bores may be accessed via the plurality of holes when the template card is in the first position. A second subset of the bores may be accessible via the plurality of holes when the template card is in the second position. The wall box installation tool may comprise two template cards that each may be slid from a first position to a second position. A first subset of bores may be accessible via the first and second template cards in the first position, and a second subset of bores may be accessible via the first and second template cards in the second position. In addition, a third subset of bores may be accessible via the first and second template cards when first template card is in the first position and the second template card is in the second position. 
     The wall box installation tool may be used to drill one or more pilot holes associated with the configuration of electrical devices that are to be installed in one or more wall boxes. For example, the guide ring of the wall box installation tool may be inserted in a first hole drilled in a wall. The wall box installation tool may include a level that may be used to level the wall box installation tool when installed in the wall. The template card(s) may be adjusted to correspond to various electrical device and/or electrical wall box configurations. For example, if the wall box installation tool has two template cards, the first template card and the second template card may be moved into position based on a selected configuration of electrical devices. One or more pilot holes may be drilled at the locations of the holes and bores associated with the selected positioning. The wall box installation tool may be removed from the wall and one or more second holes (e.g., 68 mm diameter hole) may be drilled at the location of the one or more pilot holes. Remaining wall material between the first hole and the second hole may be removed to allow for installation of one or more wall boxes. 
     A wall box installation tool that includes a template body, and plurality of levels is also described herein. The template body may have a guide ring and a plurality of bores that extend through the template body. The guide ring may extend from a rear surface of the template body, and may be configured to be installed within a pre-drilled hole in a wall. The plurality of levels may be positioned at oblique angles on the template body. A first subset of the bores may be aligned with a first level of the plurality of levels, such that the first subset of the bores may be horizontal when the first level is level. A second subset of the bores may be aligned with a second level of the plurality of levels, such that the second subset of the bores may be horizontal when the second level is level

     DETAILED DESCRIPTION 
       FIGS.  1 A- 1 G  depict an example wall box installation tool  100 . The example wall box installation tool  100  may allow for alignment and spacing of multiple adjacent wall boxes. The example wall box installation tool  100  may allow for the installation of non-standard wall boxes as well as locating and aligning multiple adjacent wall boxes. For example, the example wall box installation tool  100  may be used as a template for a desired wall box configuration and/or electrical device configuration. An electrical device configuration may include one or more standard and/or non-standard electrical devices installed in a single gang wall box, a multi-gang wall box, and/or multiple wall boxes. The example wall box installation tool  100  may allow for mounting of adjacent wall boxes for standard electrical devices, such as switches and receptacles, and non-standard electrical devices, such as a keypad of a load control system. The example wall box installation tool  100  may be used as a template to mark and/or drill one or more pilot holes for the installation of one or more wall boxes in which standard and/or non-standard electrical devices are to be installed. Example of non-standard electrical devices (such as keypads) are described in greater detail in commonly-assigned U.S. Patent Application Publication No. 2016/0307714, published Oct. 20, 2016, entitled CONTROL DEVICES HAVING INDEPENDENTLY SUSPENDED BUTTONS FOR CONTROLLED ACTUATION, the entire disclosure of which is hereby incorporated by reference. 
     As shown, the example wall box installation tool  100  may include a template body  110 , a first template card  120 , and a second template card  130 . The template body  110  may define a front surface  112 , a rear surface  142 , and a rim  114 . The front surface  112  may have a rectangular shape. The rim  114  may extend at a perimeter of and substantially perpendicular to the front surface  112 . The template body  110  may include a guide ring  117  that extends from the rear surface  142  of the template body  110 . The guide ring  117  may extend a distance D 9  beyond a bottom edge  148  of the rim  114  (e.g., as shown in  FIG.  1 C ). The guide ring  117  may be sized to correspond to a standard wall box size and/or a standard hole saw. For example, the guide ring  117  may have an outer diameter of 67 mm or 68 mm. Although the guide ring  117  is depicted as having a circular shape, the guide ring  117  may be square-shaped or rectangular-shaped. 
     The front surface  112  may define an opening  116 . The opening  116  may be aligned with the guide ring  117  such that the opening  116  defines the inner diameter of the guide ring  117 . The front surface  112  may define an orifice  119 . The orifice  119  may be configured to receive a level  170  (e.g., such as a tubular spirit level). The front surface  112  may define one or more additional orifices that are configured to accept one or more additional levels. For example, the front surface  112  may define an orifice to receive an additional level that is oriented perpendicular to the level  170 . The template body  110  may include a plurality of fingers  146  that extend from the rear surface  142  of the template body  110  at the edges of the orifice  119 . The fingers  146  may be configured to secure the level  170  within the orifice  119 . The level  170  may be secured within the orifice  119  such that it can be read via the front surface  112 . 
     The template body  110  may include protrusions  122 ,  132  (e.g., bumps or nubs) that extend from the front surface  112  of the template body  110 . The first protrusions  122  may be received in respective openings  123  in the first template card  120 , and the second protrusions  132  may be received in respective openings  133  in the second template card  130 . The protrusions  122 ,  132  may be configured to engage the first template card  120  or the second template card  130  to enable a template selection. The protrusions  122 ,  132  may be arranged along a horizontal centerline  158  of the guide ring  117 . For example, the first template card  120  and the second template card  130  may be moved, independent of one another, to enable the template selection. The template selection may be associated with a wall box and/or electrical device configuration. The protrusions  122  may be configured to hold the first template card  120  in place (e.g., in a selected position) on the front surface  112  of the template body  110 . The protrusions  132  may be configured to hold the second template card  130  in place (e.g., in a selected position) on the front surface  112  of the template body  110 . When the first and second template cards  120 ,  130  are moved, the protrusions  122 ,  132  may exit the respective openings  123 ,  133 , and the template cards may flex slightly to allow the template cards to move over the protrusions until the protrusions are received in another pair of the openings. 
     The template body  110  may also include a plurality of triangular wedges  124 ,  134  that extend from the front surface  112  of the template body  110 . The first template card  120  may include a plurality of notches  125  on each side of the first template card, and the second template card  130  may include a plurality of notches  135  on each side of the second template card.

The bore  141 E may be a distance D 5  from the vertical centerline  156 . The bore  141 F may be a distance D 6  from the vertical centerline  156 . The bore  141 G may be a distance D 7  from the vertical centerline  156 . The bore  141 H may be a distance D 8  form the vertical centerline  156 . 
     The first template card  120  may be retained by a plurality of clips  118  that extend from the front surface  112  of the template body  110 . The clips  118  may be L-shaped and may extend over the first template card  120 . The clips  118  may be configured such that the first template card  120  can be slid along the front surface  112  between the top edge  102  and the bottom edge  104 . Each of the openings  123  may be configured to engage one of the protrusions  122 . 
     The first template card  120  may include a plurality of holes  150 ,  152 ,  154 . The openings  123  that receive the protrusions  122  may be aligned with one or more of the plurality of holes  150 ,  152 ,  154 . In addition, the notches  125  on each side of the first template card  120  may be aligned such that a pair of the notches  125  correspond to one or more of the plurality of holes  150 ,  152 ,  154  when the notches  125  are engaging the triangular wedges  124 . For example, the first template card  120  may be moved (e.g., slid) from a bottom position  172  when a top pair of the openings  123  engage the respective protrusions  122  to a top position  178  when a bottom pair of the openings  123  engage the respective protrusions  122 . The first template card  120  may include one or more intermediate positions  174 ,  176  between the top position  178  and the bottom position  172 . 
     As shown in  FIG.  1 A , the clips  118 ,  128  are configured to constrain the first template card  120  and the second template card  130  to moving from the top edge  102  to the bottom edge  104  (e.g., vertically). Alternatively, the template body  110  may be configured to allow the first template card  120  and the second template card  130  to be slid along the front surface  112  in a direction parallel with the top edge  102  and bottom edge  104  (e.g., horizontally). 
     Each position of the first template card  120  may be associated with an electrical device configuration. For example, the bottom position  172  may be associated with a first configuration  182 . The first configuration  182  may be a four-gang control device configuration (e.g., a four-gang keypad configuration). A first intermediate position  174  may be associated with a second configuration  184 . The second configuration  184  may be a single-gang receptacle configuration.

In addition, the notches  135  on each side of the second template card  130  may be aligned such that a pair of the notches  135  correspond to one or more of the plurality of holes  160 ,  162 ,  164 ,  166  when the notches  135  are engaging the triangular wedges  134 . For example, the second template card  130  may be moved (e.g., slid) from a bottom position  173  when a top pair of the openings  133  engage the respective protrusions  132 , as shown in  FIG.  1 F , to a top position  179  when a bottom pair of the openings  133  engage the respective protrusions  132 . The second template card  130  may include one or more intermediate positions  175 ,  177  between the top position  179  and the bottom position  173 . 
     Each position of the second template card  130  may be associated with an electrical device configuration. For example, the bottom position  173  may be associated with a first configuration  183 . The first configuration  183  may be a single switch gang and/or a double switch gang configuration. A first intermediate position  175  may be associated with a second configuration  185 . The second configuration  185  may be a triple switch gang configuration. A second intermediate position  177  may be associated with a third configuration  187 . The third configuration  187  may be a quadruple switch gang configuration. The top position  179  may be associated with a fourth configuration  189 . The fourth configuration  189  may be a double receptacle gang configuration. 
     When the second template card  130  is in the bottom position  173 , bore  141 E may be accessible via hole  166  of the second template card  130 . When the second template card  130  is in the first intermediate position  175 , bore  141 D and bore  141 F may be accessible via holes  164  of the second template card  130 . When the second template card  130  is in the second intermediate position  177 , bore  141 E and bore  141 H may be accessible via holes  162  of the second template card  130 . When the second template card  130  is in the top position  179 , bore  141 E and bore  141 G may be accessible via holes  160  of the second template card  130 . 
     A first hole (e.g., a 67 mm or 68 mm diameter hole) may be drilled in a wall (e.g., by an electrical wall box installer) at a desired location for one or more wall boxes. The wall box installation tool  100  may be used to drill one or more pilot holes for the installation of one or more wall boxes in which electrical devices are to be installed. The wall box installation tool  100  may be installed in the wall. For example, the guide ring  117  of the wall box installation tool  100  may be inserted in the first hole drilled in the wall. The rim  114  of the wall box installation tool  100  may be flush with the wall when the wall box installation tool  100  is installed in the wall. The level  170  may be used to level the wall box installation tool  100 . The wall box installation tool  100  may be adjusted to select a wall box configuration (e.g., as shown in  FIG.  1 G ). For example, the first template card  120  and the second template card  130  may be moved into position based on the selected wall box configuration and/or electrical device configuration. When the wall box installation tool  100  has been adjusted, one or more of the bores  141  may be accessible via the front surface  112  of the wall box installation tool  100 . For example, the bottom position  172  of the first template card  120  may be used to mark and/or drill a pilot hole through bore  141 B. The wall box installation tool  100  may be removed from the wall and a second hole (e.g., a 67 mm or 68 mm diameter hole) may be drilled at the location of the pilot hole. Remaining wall material between the first hole and the second hole may be removed to create a wall opening. A wall box may be installed in the wall opening. 
     As shown in  FIG.  1 G , the position of the first template card  120  and the second template card  130  may correspond to various electrical device and/or electrical wall box configurations.
