Just out on site it's very cold, wet haven't got regs with me. Just looking for some help. That's all.
What voltage are you operating at????
He stated 230v
It was motorway spec cable. 150Ohms/L is the minimum.
Good evening gents.
Thanks for the helpful advice where given. Warm and dry now. Sorry for the lack of info. It was motorway spec cable. 150Ohms/L is the minimum. Was not thinking straight due to the frost bite setting in but knew it was there abouts.
Think sometimes to often when a question is asked on here the answer is look at the regs. Sometimes you need a little help in a shtt situation.
Cheers
The original question asked what the minimum IR value for a 230v cable is as a regs book wasn't to hand, that implies the OP required the minimum value stated in bs 7671...which is 1 megohm!
I'm confused. What exactly does this '150Ohms/L' mean?
