RELATED APPLICATION 
   The present Application for Patent is a continuation of U.S. patent application Ser. No. 11/128,887 entitled “Method and Apparatus for Electrical Box Repair Cover” filed May 13, 2005, pending, by the same inventor and is hereby incorporated herein by reference. 

   FIELD OF THE INVENTION 
   The present invention pertains to electrical boxes also know as junction boxes. More particularly, the present invention relates to a method and apparatus for an electrical box repair cover. 
   BACKGROUND OF THE INVENTION 
   Electrical boxes, also known as junction boxes or boxes, are the predominant method for making and terminating electrical connections to other devices, such as, but not limited to switches, outlets, etc. 
   Often when connecting an electrical device to electrical wiring a cover of some type is used to protect the wiring and/or the device from environmental elements, such as, but not limited to rain, nesting insects, etc. 
   Sometimes the fastening means for securing the covers to the electrical boxes become inoperative. For example, screws used to fasten a cover to an electrical box may be over tightened resulting in stripped threads or stripping the “boss” into which the screw is treaded. Replacing an electrical box because of stripping is problem. 
   Weather and age may also corrode these boxes and covers over time. When screws become corroded and rusted, the heads may break off and as a result there is no way to reattach a cover to a box. If you have multiple conduits and electrical wire running through these boxes, it makes replacing the electrical boxes a very hard and time consuming job. These boxes may still be safe, however, there is no way to attach a cover to them and as a result the box may need to be replaced. This presents a problem.

   One of skill in the art will appreciate that the present invention has many variations only a small sample of which are illustrated in the Figures. For example, referring to  FIG. 1 , a variation on clamp  100  may be a rectangular clamp requiring only a single screw for closing, for example, in this variation, legs  104  and  124  may be one contiguous leg and screw  117  and tabs  112  and  132  may be the means of tightening variation on clamp  100  to an, electrical box. 
   Other variations may include, but are not limited to, a rectangular frame that may be slid over an electrical box and secured with a cam-like screw mechanism. Another variation is a push-over frame with one-way gripping prongs which when a face plate is secured to it will “dig” into the electrical box. Other variations may include crisscrossing straps around the electrical box, raised bumps for gripping on the straps and/or clamps, straps that go over the top and/or bottom of an electrical box, etc. 
   While the Figures have illustrated a “free standing” electrical box, the invention is not so limited and my be used on other electrical boxes as well, for example, back mounted, side stud mounted, etc. 
   Thus a method and apparatus for an electrical box repair cover have been described.
