Rated 2 out of 5 by from disappointed chose this purely for its dimensions not being a frequent user of crabtree units, metal units for domestic use have been required for some years now so disappointed to find the following, 1. rated at 100amp but the knockouts not suitable for 25mm tails gland. 2. all the style of a biscuit tin,watch out for sharp corners. 3. knockouts have to be struck from the inside out,not so easy. 4. rcds not readily available for this unit rcbo,s only solution. screwfix list and stock rcds but these are for split load only ,not mentioned, and are no use. wasted much time returning and replacing. previous review i wrote dissapeared with no feed back as to why.

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.
