    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...

    Neutral Conductor Size - Main Switch to Neutral Bar

    Don't come across this very often - but I've had a CU delivered for a caravan job (not static btw), and it's been supplied with a neutral conductor from the main switch to the neutral bar! Definitely an oversight, but I've got plenty of singles cable in stock, so rather than send it back, I...

    3-blade 240VAC Dryer Socket, Where is the Ground or Where is the Neutral?

    My California dryer wall socket has 3 blades shown in picture. I measured across bottom 2 blades = 240VAC. I measured top L-blade with one of the bottom blade = 120V. Is the L-blade a neutral? If yes, why no Ground blade? If the L-blade is Ground instead, then why no Neutral blade? I tried...

    Is this a fused neutral cutout?

    I’ve not seen one of these before and i have a memory of them needing to be upgraded by the DNO. Just wondering as well what the BSEN is for it. Is it 1361 or 88-3

    Can I tighten neutral circuit breaker wires without turning off power?

    I have some lights flickering in the house. I was told tightening the circuit breaker wires in the electrical boxes might help eliminate the flickering. Is it possible to tighten the wires without having to turn off power to the house. Thanks

    Neutral and ground separated in Main panel

    Why would neutrals and grounds be separated in a main panel? This is a new build with GFCI breakers for the range and dryer; does that have something To do with it?

    Electricity flow and the role of Neutral

    A numpty question.... In domestic electrics, can one be electrocuted by the neutral wire when there is no short circuit fault? All the online videos suggest that current flows through live and back through the neutral. If the current going out through live is not the same as the current...

    Hi My house apparently is wired in an old fashioned way with what I believe is called a shared neutral ??? Dont really know. But my breakers are special they turn two circuits off at a time and instead of a black wire only, one breaker has a black and the other a red. So, I need to hookup a...

    20amp RCBO neutral fly wire only 1.5mm

    Why does a 20amp RCBO come with only a 1.5mm neutral flywire when you are driving a 2.5mm power circuit. Aren't you creating a choke, & potential voltage drop. I appreciate it can carry 20amps but it doesn't make sense to me
