Abstract: A wall cavity electrical cupboard system is provided for allowing flush mounting with ready electrical access wiring that is received through holes of the cavity container and can feed along the circumferential channel and into holes of the template openings and can be connected to control means in the electrical mounting module mounted on the support brackets such as fuses, surge protectors, short circuit protection cutoffs etc. Only the front switches or indicators appear through cut outs. The channel and the template openings provide a benefit that the wiring therefore can be selectively moved around and readily connected without needing to line up the holes of the cavity container and the electrical container and with adjustability and safety of placing wiring connection behind the sealing protector plate covering the opening except for what is allowable to show through the cutouts and be mounted on the support brackets.
