Two Distribution boards supplied by one sub-main

AdrianWint

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......

    An inspection on Friday saw a 200A switch fuse protecting a distribution circuit that supplies a busbar chamber that in turn supplies several more distribution circuits. Very common design approach. In terms of the concept, absolutely nothing wrong so unless there is something else in your situation that is causing concern, then it should not require a code. 
    mind you, I do regularly see chaps giving code 2 for some reason where a protective device has more than one wire connected!
