I have been to look at a friends flat that he lets out. As result of EICR he had to have the old Wylex fuse board changed for a Fuseboard consumer unit. all RCBO.
This want done by me.
After the electrician left, the tenant complained that the electric underfloor heating was tripping the two 20A RCBOs on the two UFH circuits. He returned and swooped the B20 RCBOs for C20 MCBs. But the problem persists.
as background, each UFH zone is 24v and there are huge toroidal isolating trannys converting 230 to 24v. One is 1.25Kk snd one 2.2KW.
I’ve checked everything, and it all worked fine with the old Wylex, I plan to swop out the C20 MCBs for 20A fuse carriers with 20A BS1361 Fuses as I think the in surge is doing the dirty.
I cannot see a fuse carrier for the Fusebox CU. Does anybody know if they exist and/or if another (I’m thinking Hager) fits the Fusebox Busbar alignment. ???
note: I don’t like mixing makes in a CU, but sometimes.,,,
