Abstract: The present invention is directed to an electrical outlet box assembly comprising a mounting plate and a modular outlet box. The modular outlet box houses an electrical device and can be coupled to the mounting plate. The modular outlet box having a first contacts module that connects with a conduit from the main power source. The modular outlet box further comprises a second contacts module having contacts for electrically connecting to the electrical device. A conductor link electrically connects the first contacts module and the second contacts module. A circuit breaker housed in the modular outlet box interrupts the conductor link to regulate the flow of current from the first contacts module to the second contacts module.
