Garage Supply Question

[jaypp]

after checking bonding etc complies, you could split tails to new board, leaving existing unaltered. I personally don't favour this as it's a 'work around' and means possible safety issues on existing are ignored/missed.


edit; i assumed (perhaps incorrectly) existing board was in garage

But if the exciting install tests out fine.....why would you need to change it at all???
Only the new install, depending on the erection method may need RCD protection.
But you could mention the benefits of a new cu to the customer without putting pressure on them to change it.

I would rather change the exciting cu also but that's not always necessary. If the new install cable to the new cu was clipped direct, then it may not need rcd protection!!
But as you say, need to check for main bonding.
