Rated 5 out of 5 by from Proper industrial std. gear Decent industrial standard British branded. equipment from Electrium, same standard as Wylex. For the record, all consumer unit main switches come as 100A, however it is not so likely that a 4-way DB would be loaded up that much; most sparkies just hole-saw out what we need if large tails. Industrial utilitarian finish might not suit a living room wall! Main RCDs (RCCBs to BS-EN.61008) readily available from elec. wholesalers if needed, or else buy a main-RCD DB. Not designed for split load as so small there'd only be 2-ways left, however RCBOs are appropriate. Will out perform inferior brands by many years.

Rated 2 out of 5 by from Wrong Answer Crabtree gave Pete3's the wrong answer to his question. He asked (and I wanted) to replace the isolator completely using an RCD. This would have resulted in a CU with x1 RCD (used for isolation as well as RCD protection) plus x4 spare ways for MCB's. Crabtree say you can, but gave the wrong part number, and I see no sign of the correct part anywhere; I don't think they make one. The part they list was for a split board. The CU doesn't even have a split-load bus bar. This needed an RCD with an input for a Live cable as per the isolator's design. It has 2 spade's to jumper across x2 busbars. The only solution is to use RCBO's - which cost more. Not only that, I wasted a day traveling to site with a part that didn't fit.

Can the 100A switch be replaced with an RCD?

Asked by: Pete3
Yes, for example a 63A 30mA RCCB would be SKU: 29042 (Crabtree Starbreaker 63A) or SKU: 9544P (Crabtree Starbreaker 80A). As always do not use other manufactures brands in our Crabtree units as this will invalidate any warranty. Thank you for your interest in Crabtree.
