Hello to all. Going to start a rewire on a large old house. It will form one part of my Part P assessment. It has three floors, two bed top floor plus a cellar (2 X freezers down here needs unprotected), electric showers X 2, smoke detectors, a one room studio type garden building, etc, etc. One loft space will eventually be converted to possible self-contained bedroom / study so ideally provision for own light and ring circuit, in all 6 bedrooms. Large kitchen needs own ring as extends out at back of the house so if included in just single downstairs ring it would inbalance the load, I know recommended anyway. Runs are long, front to back and to the top floor and need to divide ciruits as per 7671 so quite a few circuits estimated and also need to include spare capacity.
My question is, I want to split the circuits using dual RCCB consumer unit which includes non-protected as appropriate but to date the CUs with most ways to accommodate the above that I've located have max 20 / 21 ways, ie; the Hager VC876U which can provide main switch / 1 unprotected way / 80A RCCB & 7 / 80A RCCB & 6, but as indicated the switch, RCCBs use 6 ways leaving only 14 ways, only one being available for unprotected. Quick response having asked their tech dept if anything bigger, gave suggestion of two row metal enclosure giving 2 / 10 / 14 after switch etc fitted but enclosure rarther large at 390mm X 468mm. So any suggestions as to any other CU able to take the VC876U configuration but with more ways, or perhaps you've not found Hager's suggestion too out of the ordinary especially as the customer wants the CU at the top of the cellar steps not anywhere else in the house?
Further points on other matters will follow.
