I want to power the outlets from grid power without back-feed powering the...

    Switch fuse or rotary isolator?

    Hi we have been asked to run a 3 phase supply into a boiler house to feed a DB fed from next to the existing meter. Would we need to install Tails to a switch fuse or could we just install a rotary isolator? Just tight for space near the Meter and switch fuses are big. Thanks

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

    An isolator had heat damage and was replaced, not by me, but the new isolator is 125A instead of 40A. They found one and threw it on. 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.

    3 phase rotary inverter from single phase.

    My 3 phase cnc lathe is rated at 27 Amps on the manufacturers website. When I mentioned that I want to run from a single phase via a rotary inverter I was told that it will need 27 A per phase therefore 3x27=81 Amps from my single phase. Is this correct? I reckon the machine is about 5hp.

    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.
