    This fault has me confused!

    One break could well be a badly made joint where he has plastered the cables into the wall (assuming there must have been some attempt to join them to give the rn continuity). If the failed sockets had some significant loading between them, then another weaker joint may have since failed due to...

    UK Can I use a 3 pole isolation switch as a basic trigger switch?

    A neon across the switch terminals would probably not work in this setup, as the neon may well pass enough current to constantly trigger the fan.

    ELECTRIC TRIPPING

    The washing machine may not be a write off, if it does turn out to be where the fault lies. If it has been used and abused daily for 5 years, then perhaps its not worth paying someone to investigate. However, if you live alone and only use it a couple of times a week, and it is in good...

    Workshop Q light gauge 220v can a 3 phase 415v connection be made up?

    Is the farm workshop closer to where your new house will be built (than the 300m to the existing supply)? If so, you could get the new supply to your new house installed (perhaps into a small shed or something for a temporary site supply) and then take a feed from there. As you increase the...

    UK Lights going off when others switched on

    It sounds like someone has replaced all the fitting/switches, perhaps to make it look better for the sale, and just guessed at what wires go where. It shouldnt take too long for a decent electrician to trace everything out and put it all back to how it should be. If you suspect the previous...

    EICR when not in a scheme.

    Unless you are 100 percent confindent you are never going to make a mistake, and no fault is ever going to arise on an instalation you have tested, you will need to be able to prove that you were competent to carry out the tests. Also, insurers would be unlikely to cover you for professional...

    UK Switch

    The connections on the back of that switch would need to be fully enclosed. Such an enclosure would probably have to be larger than a cable mounted switch, to fit eveeything in. Something like this should be small enough? https://www.toolstation.com/axiom-inline-switch/p76089

    Main switch to RCD cable

    Whilst I understand the need to replace heat damaged components (or components which have corroded due to arcing etc), I cant see how there could be any hidden damage to a copper busbar. Copper melts at 1085 degrees, and I cant see that happening to metal that thick, without leaving more serious...

    Electric Shower Problem

    If it's an Electric shower then the temperature is usually regulated by slowing the flow rate of the water so it spends longer on the element to make it hotter. There are normally 2 power settings and then a dial to regulate the flow. If the flow rate doesnt increase gradually as you turn down...

    UK Temp extension cable for welder

    Any set up which leaves 2 plugs connected together will mean the pins remain live on the first one to be unplugged if the second one is still plugged in and so should never be done. If you happen to know anyone with a 6mm 32A cable (with cee form connectors) you could step up and run that and...

    UK Does this wiring look ok?

    Who carried out the work? Do you know how the joints have been made under the tape? Is this all going to be plastered in? From whats is visible... If the cable joints are crimps, then they could be ok if enclosed in heatshrink, better if they are in one of the socket boxes. They definitely...

    UK RAK Resort LED Mirror with Demister Pad and Shaver Socket

    An isolator will most likely be outside the bathroom, could be above the door, or low down next to a socket in the hallway or something. Or could even be in a cupboard somewhere. It will most likely look like this if there is one...

    COAX cable removal ?

    Are there other points that need to stay working? If so (or if you think its a powered amp that you can't turn off) it would probably be a good idea to seperate the centre core and screen to make sure they arent shorting out, as this could stop the rest from working. Chopping through them with a...

    Alarm Panel Fault

    Sorry missed that bit.

    Alarm Panel Fault

    I might be too late here, but before paying for a whole new pannel, it would be worth checking the cabling between the main panel and the keypad. It could be that one or two of the cores carrying data have become disconnected, but the power is still coming through.

    2 Consumer Units or 1?

    As others have said, a circuit per room might be a bit overkill. It would probably be a better use of the budget to get quality materials and a good electrician that isnt going to rush things. It would then be very unlikely that a fault would occur on the instalation. It is deffinitely worth...

    Upgraded supply needed?

    At this scale you may almost be requirng the services of an electrical design engineer, rather than just a local electrician. I would imadgine there are many electricans out there that are capable of designing this instalation, but there are also many out there that aren't, and some that think...

    UK Do I need to change to an 18th edition board when rewiring a house?

    As others have said, having RCBOs would bring added benefit over a dual RCD board. With regards to the price, £600 would be a reasonable price for the job of replacing a consuner unit if no other work was to be carried out. But all of the testing work will have to be done anyway if all the...

    Smart meter install failed

    There isnt one specific line that states that you must have a fuse. Your method of fault protection for the sub main cable is ADS or automatic disconection of supply. To facilitate this, you need a fuse or MCB upstream of the cable to disconnect ir in the event of a fault. You also need this to...

    Rcd failure

    I found a BG RCD in my brothers house that wouldnt trip under test. Switched it on and off a few times and it tripped at a much higher current. After a lot of turning on and off to free it up I got it down to about 50mA on ramp and about 60mS on 5x current I think. So I guess it had siezed somehow.
