    Adding a second consumer unit off the main switch

    Hi all, I need to add a second, 4 way, consumer unit at a customer's house. I have bought the unit and some 16mm tails. Would I be able to add those 16mm tails into the main switch of the primary CU or would I need to put a Henley block in the orginal tails? Thanks very much
