I have a 4 pole 32A Rotary Isolator switch which I am planning to use to Isolate the supply to a Hot Tub. The supply is fed from a 3 Core 6mm2 SWA cable.
The Isolator switch is obviously designed to switch 3 phase and Neutral and has two other earth connection points.
My question are -
Why is the Neutral connection point smaller than the other 3 connection points (It does not indicate neutral on it but it seems a safe bet) - allowing only a smaller cable to be connected to it?
Can I use one of the phase connection points to switch the neutral instead since I am only single phase anyway?
I assume I connect the 3rd core (used as Earth) along with the Armour to the earth connection points and this remains unswitched?
The switch is CED Rotary switch supplied by Screwfix.
Advice appreciated.
After I have finished the complete installation will be inspected, tested and certificated by a Part P qualified electrician - but I'm trying to get it right from the start and don't want to look a complete idiot.
Thanks...
Maurice
