    Parts for Switched fused isolator

    As per normal I was in a rush and didn't get enough information. I was working in an apartment that didn't have any power and when I went to restore it I found the fuse/carrier was missing from the isolator in the switch room, I'm guessing the extra cautious handyman has removed it to prevent...

    Do they make 2 pole isolator light switches and modules?

    My kitchen had an extension at some point and the 2 lights are switched from a 2 gang light switch. It's separate circuits so I can't join them together, ideally I need one module to switch both circuits switch lines, so the lights come on together. Then use the other gang for something else...

    Electrician to connect tails after isolator fitted (EDF)

    If there isn't a 2-pole isolator there already, I usually get the client to arrange to get one fitted before I do a board change, either through their energy supplier, or (if they also need a PME earth, or their energy supplier is faffing around) through National Grid (formerly WPD). Every time...

    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.

    Can a wireless switch be used to control flow to an isolator switch?

    Hi there, (noob DIYer here!) Recently moved in and I have an inline extractor fan in my bathroom, which goes up into a crawl space in the loft then out the back of the house. For some reason, whoever installed the isolator thought it would be a good idea to have the isolator switch up in the...

    Hello, I’m about to take on a mains room for a block of flats and the DNO are giving us a supply of 259kva. Now, would I need a 200amp TP-N isolator or a 400amp TP-N isolator from the main head to the ryefield board? I am also assuming I will require a CT chamber. This is my first project of...

    Having a discussion the other day with a kitchen fitter who “also does electrics” and he is adamant that a NIC contractor told him that a meter isolation switch has to have the supply go in the bottom and the load out the top, same as a MCB. This convo came about as he said the property we were...
