When do Neutrals need to be switched? Discussion ThreadWhen do Neutrals need to be switched? Electrical Advice
Sorry if this is a silly question but I can’t get an answer from colleagues as it’s a “I dunno”. So I thought I’d ask here!
Some of our TPN DB’s have a 3 pole main switch with a block for the neutral. Other TPN DB’s we have here have a 4 pole main switch which switches the neutral.
It’s the same for our machine isolators. Some have a 4 pole rotary switch and others have a 3 pole rotary switch with a connector block for the neutrals.
When do we need to switch neutrals & why?
Apologies again if it’s a silly question or something I should already know. I’d like to learn.
Thanks guys.
