I.S Terminals
I.S Terminals
(OP)
Our site installation instructions require I.S terminals to have of 50mm clearence from the side of a metal enlosure (which itself is bonded to plant earth)
Is this required in European or IEC standards?
Thanks,
Alan

Thanks for your reply, I was tring to find this in BS EN 60079 but this standard only quotes the 50mm clearence distance between I.S & non I.S terminals as you have mentioned.

I've looked in an old version of BS EN 50020 & noticed the 3mm requirement. I allso noticed the minimum distance between I.S terminals of different loops is 6mm. I'm certain I heard recently that this has since been reduced in newer standards, would you know if this is the case?
Thanks,
Alan
