The Client contacted our business asking for a new, clean consumer unit. Upon our initial visit we found that the incoming tails were two differnt sizes, installed within the blockwork cavity and not installed within the zones prescribed in regulation 522.6 BS7671. We also found that not all of the circuits were RCD protected.
A brand MK new metal consumer unit was installed whilst also removing the old redundant data cables. New 25mm supply tails were installed in fully accessable PVC trunking and the full installation was tested and labled accordingly. All circuits now have RCD protection, ensuring the safety of the property and family.
What is an RCD
RCDs do not detect whether a circuit is overloaded or not, rather it detects the integrity of the circuit. If there is damage to a cable, compromise as a result of water or a faulty appliance, an electrical current will flow where it shouldn’t and could cause an electric shock before the circuit is overloaded. Consequently an MCB does not always offer complete protection. By detecting even the smallest fault currents and having a split second disconnection time, RCDs protect from electric shocks, or at the very minimum, injury from electric shock.
New requirements set in the 17th edition regulations state that there should be RCD protection for sockets, the electrics in your bathroom or shower room, circuits intended to supply mobile equipment outdoors and for cables buried in walls. Since the wiring in most of the homes up and down the country runs underneath the plaster of the walls, it means every circuit in your home should be RCD protected.
