Equipotential bonding in bathroom

[Mogweed]

What size conductor should be used to bond everything that's metal to everything else that's metal in the bathroom (but not run back to the CU)?

Cheers,

Mogweed.

Correct.

or 6mm2 bare.

Wrong. Bare protective conductors, whether circuit protective conductors or equipotential bonding conductors, are not permitted for sizes of less than 10 mm^2. [See regulation 543-03-02]
