Hi,
I've only touched SWA a couple of times and I just wanted to know how the SWA gets terminated at the consumer unit. I know you use glands but how does it get terminated to the plastic consumer unit using the metal sheath as the earth. Are there any special requirements?

If it's a cheapo dis board you will have problems, the crappy plastic bends when you breathe on it. 6mm brass bolt thru banjo, earth crimped to lug on brass bolt then carry onto earth bar. Even if it was an m/c dis board you should still do the same.

hey have started to wire a hot tub, and the rotary isolator i have used has to have a plastic adapter ring to allow the swa to exit and enter it, meaning i can't earth the armour with a banjo, anyone else have this prob and know ways around it???

I take it the piranha nuts are the way forward. Never used them before, will it be able to clamp a 2.5mm swa into a 25mm knock out in the isolator box, and still keep the IP rating of the isolator tho?? cheers.

Where do the other ends of the SWA go? If you're not using the armour as the CPC you only need to earth one end of the armour.

Assuming that the hot tub is single phase and you are using either 2 core or 3 core 2.5mm2 SWA the correct gland should be a 20S (either BW or CW depending whether indoor or outdoor) so realistically you will need to fit a reducer to attach the gland anyway. What make isolator is it?

If it is a three phase hot tub please ignore the above ramblings.
