    Whats the best way of making good this lighting problem? In a dist. board, there are 3 x separate fuses feeding 3 x separate lighting circuits. However, the 3 circuits share the same neutral back to the distribution board. A notice has been given to put this right. It's impracticable to run out...

    4 pole rotary isolator... Switch the neutral or not?

    Hi there, Just a quick question. I am rectifying many problems on some 3 phase immersion heater circuits in a plant room. There are 4 pole rotary isolators just before the immersion elements and the earthing arrangement is TN-S. I noticed that the neutrals are connected into a dedicated...

    How to track down a bad neutral in a home electrical circuit

    Ok, please be aware that I am a 'do-it-yourself-er,' so if this isn't the right place to be posting this thread, let me know where I should be posting it. The other day, my wife plugged in the vacuum cleaner and the whole living room circuit went dead. I figured that it was just either a...

    Floating Neutral

    I am a long time retired electrician, I have worked on many different systems, I was High Voltage trained among other things. I understand what floating means, but I don't understand a floating neutral. To amuse myself in my retirement, I decided to build a Solar System, something that I knew...

    Neutral Pole

    Good day. This has always got me confounded. Witha 4-pole 63A breaker, can someone please confirm/advise what the current carrying capacity of the component is? Does the 63A current stamped on the product mean 1. 63A per pole? 2. A total of 63A but limited to 63A in any one pole? If #1 is...

    AC vs DC, live vs neutral

    Hi. I've read much about ac vs dc but can't find a 'simple' answer. If current alternates 50 times per second in a uk mains circuit, why do live and neutral not swap 50 time per second? On these forums, I've read that it does, so that copper does not migrate as it would in a dc circuit. I've...

    Floating or Bonded neutral

    I just bought a Westinghouse generator (When 12000) and my neighbor is telling me no to use it until I know for sure if it is "Floating Neutral" or "Bonded Neutral" I don't really know what is he talking about. Why does it matter?

    Induced voltage on neutral wire

    Hi everyone, When checking my consumer unit voltages with the full board off, I stumbled across something head scratching. Measuring the feed from the DNO, L-N I read 242.3 V. Measuring L-E I measured 242.3 V and N-E I measured a steady 30 mV. When measuring the live side of the main of the...

    Current flow in neutral but no voltage ?

    Having a challenge understanding the concept behind why when you measure across line and neutral (live circuit) using voltage indicators we have voltage reading of 230V single phase. If there is current flow in the neutral why is it termed as 0V ? On that basis, second question - If I tested...

    most sockets show live neutral reverse

    just had a new meter fitted,tells me most sockets are faulty and not to use,all sockets apart from two show live neutral reverse. going to egypt for 2 weeks tomorrow,so can't get an electrician right now,must have been like this for years so assume it is still safe to use? any thoughts on the...

    Lost Neutral on 3 Phase system - how do you calculate the effect on line voltage

    I know the effect of a lost neutral (floating neutral) on a 3 phase system, and the theory of why the line voltages can vary. However, I have been attempting to show this by calculating the line voltages of a phase system at given loads on each phase. Lets say:- Red 296 Amps, Yellow 279 Amps...

    Unusual Neutral Tail into Consumer Unit

    Hi, Ignoring the appauling conductor terminations which I found, in the background of the photo you can see a really odd neutral tail terminated into the main switch. I've never seen this before, has anyone else, and if so what is it ? Oh I should add this is at a flat, so the tails are...

    RCD without neutral 2 phase supply

    Hi everyone, Quick question can you fit an RCD without any neutral connections? If I have a 3 pole circuit breaker which has all 3 poles terminated with a 3 phase supply (L,L,L excluding neutral or earth) on the primary side and I am using only 2 phases on the secondary side (L,L) to create a...

    Where to put unused neutral wire for light switch

    Howdy DIY soldiers, first post here. My question comes down to whether it would be particularly unsafe for me to temporarily wire nut and tape a neutral wire connected to an active knob and tube circuit and leave it in a wall behind a plastic box. I know that the "correct" answer per the NEC...
