I'm in the middle of a 'discussion' over an EICR in which the contractor is claiming that two distribution boards (in different parts of the building) but fed from the same sub-main (well, split on the outgoing terminals of the supplying switch fuse) is a C2 and needs to be changed.
He is unwilling to supply a regulation which he feels this contravenes and I'm struggling to find such a reg.
What is the opinion of the learned community?
I think this is perhaps not best practice but I'm struggling with his assertion of a C2.
Comments please......
