Moving a Consumer Unit

[Piratepete]

Hi Guys
If I move a domestic CU to a new position on an adjacent wall, what testing am I required to do?

The tails will be 0.5 metres longer, and each circuit will need to be disconnnected and then reconnected without any change to cable lengths.

Cheers
Pete :winkiss:

as a minimum, i would measure Ze, PFC, and Zs for each circuit, and global IR . obviously check/test the main bonding as well.

As above. If you change main tails/ main earth conductor, you are theoretically potentially changing the values in the tests Tel mentions.

yeah , by about 0.002 ohms for 50cm of 25mm

Ok, that's what I thought, just needed confirmation
Thanks Guys
