hi, can somebody tell me if i can wire a 3 pole relay as a single pole, i think thats what i want/need?, i needed a relay to turn on and off from - 24vac,on the coil side-, 240v 35a on the main load , and with out spending silly money i could only find a 3 pole one cheap, thats 35 amps , all i need it to do is when activated by the 24v ac , allow the current of my 240v ac to pass to make the circuit, and that can be just the live or the live and neutral, etc etc
if it can be done?, would wiring it so my live splits and goes in to all 3 poles and then out all 3 poles(when activated), to give more current, as its for my mig welder ,(24v trigger), so more amps the better, thank you

The three poles together would certainly be able to carry more current but there maybe one problem. It could be that all 3 poles would not operate together, they could be some milliseconds between each one operating and a chance for some arcing.
If you are going to give it a go I would switch the live and keep the neutrals permanently connected.
I'd be interested what others would say though.

That's what I was thinking with my very basic understanding, could do with any other input

Look at a single pole Solid State relay. Will do exactly what you want with higher currents and the coil voltage.

Don't forget to choose an AC and not DC relay
Unless you can rectify the AC into DC then maybe you could use a relay from a lorry.
Out of interest why do you need to do this, where is the 24V coming from?

im turning a always hot welder into one thats not from the relay, the 24v comes from the transformer that drives the wire feed also, basically i need 24v ac coil, and 240v drive switch

i need ac coil 20-24v ac, 240v ac on the main? cant see one with less than 80v on the ac coil
