Hi,
I'm taking swa out of the shed and fitting it along a metal fence with metal fixing band. Swa goes into a wiska box then flex from the box to a light that's bolted to the metal fence. Circuit is protected by rcd.
Does the fence need to be bonded at all? I'm guessing it's an extraneous metal part, 2.5mm unprotected / 4mm protected.
Is it enough to go from the swa banjo to the fence with a bit of 6mm? Or from the 1.5mm of the lighting circuit to the fence with a piece of 4mm?
What would you do? Many thanks if you can help.
