    Non contact pen picking up current on water pipe

    Non contact pen picking up current on my water pipes. I've turned off the boiler but it's not that. Found that it's the down stairs lighting. I'm starting out on electrics so medium to low experience. Is this a normal thing?

    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...

    Wago topjob current ratings

    Hello Can anyone confirm for me what the following spec for a Wago TopJob 2202-1201 din rail connector means? The connector can accept max 4mm solid core cable, so does this mean (see bottom row) the connector can cope with 32A? The row above says rated current is only 24A though? I’m easily...

    Current rating for tumble dryer?

    I have just bought a tumble dryer that has come supplied with A 13A fuse. The manual says it has come with a special plug, that must be plugged into a 16A rated socket. Surely if I plugged it into a 16A socket and it tried to draw more than 13A it would blow? Can I plug this into a normal 13A...

    Neutral current in a single phase installation confusion

    In a 3 phase system the neutral carries current that is unbalanced. Okay. So in a single phase domestic household the neutral carries the same current as the live otherwise the RCD will trip. So does that mean if we have a perfectly balanced 3 phase system then if I go to one of the phases and...
