[QUOTE="Sharpend, post: 490264, member: 17152"] This looks to be a 3ph supply for a HMO, hence the 3ph isolator then the Ryefield distribution board, the metering will be 1ph after the second switch fuse. the space between isolator and service head is too small to do any meaningful connections between the two. The top of isolator is too open (perhaps the installer was worried about Eddys) therefore non compliant. [/QUOTE]
