    am I certified to Sign off fuse board?

    Am I certified to sign off/do certs for a fuse board if I've completed my Level 2 and level 3 city and guilds (2365) electrical installation? (have not done the regs yet or testing & inspection or the NVQ)

    Type A rcd in series or change at the board

    I am to install a car charger that states a type A RVD is to be installed. Can this be put in the garage from the non rcd side of the board or is it better to change the RCD on the board and use that side. I assume it makes no difference

    Bringing single phase off three phase board

    Hi all, new to this thread and just looking for some views. I have today attended a industrial unit which is being converted into small individual offices. An electrician has previously been here and has taken 3 individual sub mains from the existing three phase consumer unit to single consumer...

    Smallest Sub-Main board with selectivity

    I need to fit a small sub-main board by my service head, to feed a garage unit in an outbuilding. I am thinking of using a Chint shower unit (Screwfix), but replacing the internals with a S Type Time Delayed RCD. Is this a valid approach for a sub-main, as opposed to using a switch/fuse unit...

    Fused fuse board no rcd or breakers eicr rating

    Hello I live in a rental in scotland and have recently had an EICR carried out. I have an old fuse wire fuse board on a wooden plate with no rcd or breakers, I had assumed this would be a C1 or C2 but this came back as a C3. Surely this is incorrect if the plastic fuse boards are C3s surely no...

    Removal of potential asbestos fuse board - who and estimated cost?

    [EDIT 2056] Sorry, I think I’ve got my wires crossed and OhMe haven’t been very helpful in detailing what I need to do/say to N-Power except for ‘not our problem’. It is indeed the big, green, metal box at the bottom that is the problem. Good evening, Today, I had someone out to install the...

    3 phase board with 250A incomer

    Hi guys, if a 3 phase board is to be installed, with 250A mains. With 8 32A 3 phase sockets, 8 single phase 16A sockets, 2 light circuits and 3 phase 63A socket on it, that exceeds the 250A. I understand you would have to consider diversity factor etc into it but is that still too much or would...

    DB board keeps tripping mysteriously at night

    Is it possible that a DB board can be controlled from outside the unit/house itself? We suspect that someone has been playing around with our electricity and we're wondering if that is possible. I know next to nothing about electricity other than the basics so please excuse me if this question...

    Certifying remedial including dist board swap.

    Hi, An easy question if you know the answer. My house recently failed an eicr done by me. I've had a couple of jobs I'm fixing (split ring separating into 2 circuits), and some I'm not (no cpc on plastic light switches Upstairs, presumably compliant at time of install. The lights have a...

    Wiring under skirting board

    Hi, I had what I thought was a licensed electrician extend electrics from an outlet to the opposite wall for lights in a wardrobe I'm having installed. The wardrobe builder requested a fixed spur on the wall and the cable to to be run under the floor boards. However, the electrician ran the...

    EICR certs with IR testing on an obviously live board

    How do you experienced testers do it. I’ve seen live to neutral LIM’d but Neutral to Earth and Live to earth showing >999 @ 500V. Surely pushing any voltage down a commoned neutral with live components on other circuits is asking for trouble, even at say 250V? I am 99% certain they don’t pull...

    Bad solder joint on circuit board.

    Hello all, I would greatly appreciate anyone's opinion this matter. Can this be repaired by simply resoldering? I'm concerned about the blackened area around the joint which looks to be burnt and also the wider discoloured area around the joint. Many thanks.

    Can I remove the Economy 7 Board?

    Hi all, I got Economy 7 and 2 consumer boards, but only want 1 consumer board as it'll look a lot tidier and save me replacing the E7 board as its very old and needs replacing. The E7 board only runs the immersion tank, used to run heaters too but I moved those circuits to the main consumer...

    Tesla EV charger on new distribution board

    Hi all, Will have to apologise for asking basic questions but would rather be sure. I have got an EV charger circuit to be fit in an upgrade consumer unit. The wall connector features built-in RCD Type A + DC 6mA so it is not required to install RCD type B. The board will be 100A main...

    Faulty RCD, electrical board or unknown

    Hi Hoping to get some insight from people, as I have had two electricians check the fault, to no avail. The most obvious fault is the RCD is tripping. It trips randomly. I have tried a process of elimination and it is not a faulty item. It will trip when cooker is turned on, when washing...

    Light circuit off at consumer board - but RCD / RCCB still tripped

    Hi I'm removing an extractor fan from our WC, as it's just a toilet and sink and we never use hot water in there anyway... The extractor is on the light circuit, but has it's own pull cord. I double checked by turning the fan and light on, then switching off the MCB. All good. I triple checked...
