A mate of mine bought a house and asked me to check things over. It ended up with replacement CU , among other things. A couple of months later, this is work done by a 'heating engineer', who installed a new boiler to a property. He broke into the downstairs RFC with a 20 amp 4 p joint box, under the floor.
Wow, 20amp on a RFC... I guess he just had one in the back of the van and figured waste not want not?
Just out of interest is it the case now that all boilers have to be on a dedicated radial? Or for certain sizes is it still ok to spur off the RFC to a FCU, or incorporate the FCU into the ring directly? I only ask as I noticed mine is on a ring, and I thought a few years ago there was a reg change about that. It might just be a CORGI internal standard, not a formal regulation as such.
