    Need for isolating switch

    Should a small 500W electric rad on a fused spur also have an isolating switch? Some of these small rads have fancy timers that might get confused if switched off at the wall rather than their controls.

    Isolating neutrals, working live?

    Hi, where only single pole isolation is achievable and a shutdown is problematic, what is the best practice with neutrals when connecting and disconnecting circuits? I understand that all live conductors should be isolated and we shouldn't work live, but out of the class room it is not always...

    isolating fridge

    Something is causing 1 bank or RCD (80A 30mA WRS80/2) to trip on consumer unit, intermittently. I think it may be the fridge freezer, but can't be sure. Is there a plug in unit (lower fuse rating) that I can insert between the fridge and the plug point that will trip before the consumer unit...

    Isolating grounds in Solar installation

    I have 400 Amp service split into two 200 Amp panels. I’m converting one to a protected loads panel as part of a PV solar system with battery backup.

    Faulty MCB. Problem isolating ring final circuit at CU with MCB

    I am planning to move a socket outlet. The CU is largely unlabelled so don't know which 32 MCB to switch off. There are 2 x 32a MCB. All other mcbs are for lights (6a) and a dedicated immersion (16a). To isolate the circuit, I tried switching off the first of the two 32a mcb which isolated some...

    Shaver sockets and isolating them

    With the ease of EICR's and the like, and for customers to isolate those "buzzing" shaver sockets, isn't it time we started fitting them on isolator switches, either existing fan isolators or fused Spurs? Can't believe some electricians still hang them on the live lighting circuit without any...

    Cooker isolating switch above cooker

    Hey all i know you have to install a cooker switch to either side of the cooker in a new install. However in an existing install where it is positioned above the cooker does it say anywhere that it's illegal to have it there and does it have to be moved. I know it's dangerous as if there's a...
