Swa sheath size too small

[chris day]

an outbuilding is supplied by a 50mm twin SWA cable from a PME supply

The assessor has told me to convert to a TT as the steel csa is too small, is there a way I can prove that surely a 50mm twin swa sheath is suitable to be a 16mm earth?

The options are to TT, change the cable so a core can be used as the earth, run a bonding conductor alongside the existing SWA or remove any extraneous conductive-parts that require bonding.

went on a training course yesterday. Risco Agility. it does everything bar making tea, but it's bloody complex to take in the programming side.

Fair play to you...I'm guessing you will be practising keeping your composure,whilst explaining the benefits of IPhoning the central heating up a degree...when you really think the lazy eejit should just put a jumper on,and save the planet

Those systems where you can turn on and off your heating, lighting, kettle, etc. are great when they work.
Not so great when your standing in the room in the dark and the bloody lights won’t switch on.
Good job smart phones have a torch.
