AMD 2. SPDs Shall Be Provided

whjohnson

So, again, where is the evidence that these things are actually guaranteed to 'save' your equipment? After all, if we are now required to 'sell' the concept to the customer, and then rely upon the outcome of their decision we need hard evidence that the things are actually capable of saving that "£4000 television"?

    So does adding a new circuit to an existing plastic consumer unit a non-compliance?

    Not to my mind - the addition didn't require the selection or installation of the consumer unit, so the new regulations wouldn't apply to that. The new work doesn't need to be fed from a metal clad CU in order to be safe of itself.

    The old CU might be missing some features that your new circuit might need - be it 30mA RCD protection or SPDs or AFDDs - in which case you'd have to consider how to meet that need - it might be a new CU or is might be something extra in a separate enclosure.
