17th ed and consumer unit replacement - OT query
I have an old consumer unit (Wylex) with rewireable fuses.
If I decide to replace it, will I be required to use RCD/RCBOs on all circuits (either one 'whole house' RCD, or one per way)? Currently, there's a single ring serving the whole flat (approx 85 sqm) and a recently installed ring serving the white goods in the kitchen (replacing a spur bodged in by a previous occupant). Given a fair number of switch-mode power supplies on the main ring, I'm worried that it'll exceed the leakage budget. Would a better technical solution in that case be to replace all the sockets on the main ring with RCD protected sockets, is that allowed/necessary under 17th ed - or is all this unneccesary and the lack of RCD protection 'grandfathered' in? With my luck, I should probably have replaced the CU when I had the chance before the 17th ed came into force. Cheers (or maybe not) Sid (Oh, and sorry for being strictly off topic - I won't be replacing the CU personally - I don't have the appropriate test equipment available, and more to the point, even if I hired it, I don't have the knowledge to use it properly) |
