C/U Change Submain Problem

[Paul Chick]

Hi All

Im upgrading the mains of my local pub. The board I am changing itself has 6 submains coming out of it in 16mm T&E, where does this leave me in regards to those cables and 30mA protection?

Cheers

they are previous installs and as long as they are safe to connect to your new board, don't require RCD protection under 522.6.101.

Thank you mate. Its a pain because it stumps you a little with regards to the old C/U's being fed from the board im changing. No of them have RCD 30mA protecting their circuits, i.e kitchen C/U, skittle Alley C/U, Toilets. And those boards are ancient!

Does my nut, all want it done cheap & quickly aswell! So basically from the submain is not my concern apart from the readings I take from the isolator to check dis times.
