    ATEX Neutral connection

    I have a compressor to be hard wired into a zone 1 container. The container has a 3 phase + E supply but the compressor requires a 3 phase, N & E. This is not something I have experienced before within an ATEX installation and when researching there is a few discussions on TN-S, IT and TT...

    Live & Neutral swapped on sockets?

    Hi Recently my son complained that he was getting shocks from his laptop when plugged into the mains in his room. I checked the socket and the others in his room and the wiring looked fine - red to live, black to neutral and firmly connected. I then used a plug-in Ring Main tester which...

    Open neutral in cooker

    A client has a Kenwood CK405 dual fuel range cooker, for which the smaller of the 2 ovens doesn't work. The elements tested out fine, but live tests showed that both N and L sides of the elements were at 230V to E, so presumably an open neutral. I'm guessing it's a loose connection somewhere...

    Can I confirm how to test for and how to find a borrowed neutral?

    During some testing I found a N-E IR fault on the kitchen lights of 0.1Mohms. I also found a N-E IR fault on the ring sockets, again 0.1Mohms. This could have been a coincidence, but I disconnected both neutrals from the neutral bar (i.e the kitchen lights and sockets) and tested between them...

    Are these earth wires connected to neutral?

    I found a picture online of a standard UK connection in a block of flats. Where I have circled blue, would those earth clamps around the orange cable somehow cut into the neutral wire to connect within the orange sleeving? Or are they just clamped to the sleeve for some arbitrary reason?

    What happens to the voltage/current on the neutral wire?

    If we had 4 appliances to power, one in every room of a house, Once the current passes through them all, the remaining voltage & current is said to "pass back to the source via the neutral wire" Is this an accurate mental model? From what I see, most Neutral wires are somewhere down the line...

    UK Running Neutral Wire from consumer unit to Ground henley block

    In the UK, It is said that the neutral wire is connected to ground/earth wire along the way back to the substation.

    Shared/borrowed neutral?

    Hi, I have an ongoing issue with an RCD which keeps tripping when bathroom light (not on RCD) is turned off. The issue doesn’t happen every time the bathroom light is switched off but only ever trips when I turn it off. It happens mainly at night and there doesn’t seem to be much of a link...

    Shock from neutral when changing light fitting - why?

    Hi All, I was changing a light fitting (something I've done many times before). Since it was a switched live to the ceiling fitting I had left the circuit still live (I know but no comments about that please!). Touched the neutral and got a small shock. So used a test screwdriver to see if...

    Came across this, classic example of question no fused neutral

    What's wrong with this? It supplies an immersion heater, it's not the disconnected line & neutral.
