Electrical countertop box with trapdoor cover
An electrical box assembly for mounting an electrical component in a countertop. The assembly includes an electrical box with an enclosure adapted to receive electrical wiring. A sidewall on the electrical box includes one or more channels each including a channel bottom, a ramp, and a channel cover with a slot. A mounting bracket includes a base and two arm members and is loosely assembled to the electrical box with the mounting fasteners. A cover bracket is secured in each of the slots. A cover provides access to the electrical component and includes a cover plate, a cavity for housing an electrical component, and a snap-engagement latch for selectively latching the electrical component outward of the cover plate or inward within the electrical box enclosure. Installation time and effort are minimized as site preparation requires only a single hole that may be made with a standard size hole-saw.
