1) I have a 2.5mm 4 core cable running out to an isolator, 3 phase and earth.
The SWA has a CSA of 20mm but is only equivalent to a 6.43mm copper conductor. Can I use this SWA as my Main protective bonding conductor.
The regs says the minimum size of the protective conductor should not be less than 10mm square.

I also have 3 other SWA cables going to the same isolator can I not combine these armours to form the main bonding conductor

New here?
