Is an electrical receptacle allowed inside a kitchen cupboard by the California Electrical Code? (i.e. installed so that the receptacle face plate is on the inside back panel of the the cupboard, so that an electrical device inside the cupboard may be powered). Please cite applicable section of code.
In the case the cupboard is made of wood, it seem the box face would have to be flush with the inside of the cupboard face:
In walls and ceilings constructed of wood or other combustible surface material, boxes, plaster rings, extension rings, or listed extenders shall be flush with the finished surface or project therefrom.
2010 Electrical Code, see section 314.20
