Affected: IC 22-12; IC 22-13; IC 22-14; IC 22-15
Sec. 91.
(a) The
				branch-circuit equipment shall be permitted to be combined with the
				disconnecting means as a single assembly. Such a combination shall be permitted
				to be designed as a distribution panelboard. If a fused distribution panelboard
				is used, the maximum fuse size for the mains shall be plainly marked with
				lettering at least one-fourth inch (1/4") high and visible when fuses are
				changed.

				  concerning identification of each disconnecting means and service, feeder, or
				  branch circuit at the point where it originated and the type marking
				  needed.
(b) When using plug
				fuses and fuseholders they shall be tamper-resistant, Type "S", enclosed in
				deadfront fuse panelboards. Electric distribution panelboard containing circuit
				breakers shall also be deadfront type.
(c) A single disconnecting means shall be
				provided in each mobile structure consisting of a circuit breaker, or a switch
				and fuses and its accessories installed in a readily accessible location near
				the point of entrance of the supply cord or conductors into the mobile
				structure. The main circuit breakers or fuses shall be plainly marked "main".
				This equipment shall contain a solderless type of grounding connector or bar
				for the purposes of grounding with sufficient terminals for all grounding
				conductors. The neutral bar termination of the grounded circuit conductors
				shall be insulated.
(d) The
				disconnecting equipment shall have a rating suitable for the connected load.
				The distribution equipment, either circuit breaker of fused type, shall be
				located a minimum of twenty-four inches (24") from the bottom of such equipment
				to the floor level of the mobile structure. There shall be a label attached to
				the panelboard stating:
"THIS PANELBOARD SHALL BE CONNECTED BY A FEEDER ASSEMBLY
				  HAVING OVERCURRENT PROTECTION RATED AT NOT MORE THAN _____
				  AMPERES"
(e) A distribution
				panelboard main circuit breaker shall be rated fifty (50) amperes and employ a
				two (2) pole circuit breaker rated forty (40) amperes for a forty (40) ampere
				supply cord, or fifty (50) amperes for a fifty (50) ampere supply cord. A
				distribution panelboard employing a disconnect switch and fuses shall employ a
				single two (2) pole, sixty (60) ampere fuseholder with forty (40) of fifty (50)
				ampere supply cord, respectively. The outside of the distribution panelboard
				shall be plainly marked with the fuse size.
(f) The distribution panelboard shall be
				located in an accessible location. Shall not be located in a bathroom/restroom
				and shall be permitted to be located just inside a closet entry if the location
				is such that a clear space of six inches (6") to easily ignitable materials is
				maintained in front of the distribution panelboard, and the distribution
				panelboard door can be extended to its full open position (at least ninety (90)
				degrees). A clear working space at least thirty inches (30") wide and thirty
				inches (30") in front of the distribution panelboard shall be provided. This
				space shall extend from floor to the top of the distribution
				panelboard.
(g) Branch-circuit
				distribution equipment shall be installed in each mobile structure and shall
				include overcurrent protection for each branch circuit consisting of either
				circuit breakers or fuses.
(h) The
				branch circuit overcurrent devices shall be rated:
(1) not more than the circuit conductors; and
(2) not more than one hundred
				fifty percent (150%) of the rating of a single appliance rated thirteen and
				three-tenths (13.3) amperes or more which is supplied by an individual branch
				circuit; but
(3) not more than the
				fuse size marked on the air conditioner or other motor operated
				appliance.
