Testing with 2 consumer units

[Ian1972]

Hi all, quick question, if I fit a new small consumer unit for a shower do I just test this board or do I need to test the existing house consumer unit as well ? Thanks Ian

Only the board you are fitting and any final circuits connected to it.

You must still check if the main bonding is in place.

Where is the supply coming from for your new CU?

Hi, thanks for the replys, there is a Henley block I was going to connect it to

You must still check if the main bonding is in place.

and main earthing, Ze, PSCC etc, but no need to test existing circuits from existing CU.
