    Implications of replacing a 40A with a 125A rotary isolator.

I locked it off last night and today it is back on line, deemed okay to run until a replacement arrives. This is on a 20yo piece of packaging equipment. Anyone...

    Single pole rotary isolator

    Hi everyone, I have moved into a property with a 63a single pole rotary isolator controling a inline water heater. Is this safe? Surely it should be a 63a two pole isolator switching both the live and neutral? Any advice would be much appreciated. Thanks.

    32 amp rotary isolator

    Anyone know if there is a reg in regards to supply going in to the top of a rotary isolator. We are changing the isolators over for ac units, long story short they won't reach the top terminals now, so feed can only go in bottom. Just a 2.5mm 3 core swa. Cheers

    Rotary Isolator that takes 2x16mm?

    Does anyone know of a rotary islotaor, weatherproof, that'll take 2 x 16mm incomers? I've got long runs out to parking bollards so they've had to size up the cable for volt drop. I could do it with a street light cutout but it wouldn't allow them easily isolate it. Many thanks for any help.

    Rotary Isolator choice

    When its come to 4 pole rotary isolators, do most of you use one brand or whatever is in stock at the time of ordering. Fitted 2 Gewiss ones today and thought they'd be good to work with, how wrong was I? No space in em at all, the cheaper ones from Chint and Europa seem just as good but loads...
