sub main earth

[rapier]

Ill be installing a sub main on a new build next week using 16mm twin and earth with also takin a 10mm earth from the main board.

Is it possible tht i can take a 10mm from the sub main for main bonding the water.

Thanks in advance.

Personally i would TT the sub board. That way your main bonds can run to there and not all the way back to the main board.
