Abstract
Abstract A system utilizing modular hardware for residential and commercial buildings. The system includes pre-wired molded plastic hardware and a circuit breaker panel which can be attached to electrical circuits having wire modules, and can be expanded using a circuit breaker panel extension module. It further includes smaller electrical boxes having mounting dovetails including electrical contacts for electrically and supportedly connecting a first electrical box to a second and third. A cavity is centrally disposed in each electrical box for receiving a pre-wired modular function unit and a standard function module, or a single pre-wired standard function module unit. The standard function module can be a standard switch, dual receptacle, lighting fixture, circuit breaker, or junction box and the like.
