Interlocking floor box with extended locking conduit hubs
An interlocking floor box assembly including one or more electrical boxes which may be securely ganged together to form a multi-gang floor box for mounting one or more electrical components, such as duplex outlets, directly in a concrete pour area or in a floor above a concrete base. Opposing side walls include an internal hub and an external hub respectively for interlocking two or more electrical boxes together. Other embodiments may include a tab and a corresponding slot on opposing walls on the electrical boxes to enable interlocking two or more boxes. The interlocking floor box assembly enables secure side to side interlocking of two or more boxes to form a multi-gang floor box. A cover plate and a lid assembly enable plug in of electrical cords into the duplex outlets with the plug ends of the cords recessed below the floor level.
