    An old Lighting Board.

    Thought this might be of interest to some of you. Still in operation controlling the house lights. Located in a 1900s hall. Was interested what they did regards the asbestos when a fuse wire needed replacing but there wasn't anybody around that knew. And the other end.

    Double whammy

    Switch and shower. I only usually get one or the other. Found on todays EICR, tenant still happily showering away with it (not while I was there  :^O ). Both had been very hot.

    Cable CSA

    Had an EICR today. All T+E cable, all stranded apart from the lighting. Socket circuits (ring finals) looked too small to be 4mm by my eyes but larger than 2.5, CPC was a 1.5mm solid. Red and black Strange thing was it was new in 2004, both the building and install so too new for imperial...

    Certsure tightens it's grip further?

    It's been mentioned on here the other day that certsure are ending the elecsa brand and moving members over to the NICEIC brand. I saw on another group that the electrical competent person scheme has removed NAPIT members from the listing pages, the post about it in the group was quickly...

    Fire sealing a consumer unit.

    Don't do many consumer units and since amendment 3 the ones I have done I've done top entry with trunking and the fireproof stuffing glands so the consumer unit would contain the fire. Curious to know what others do on rear entry CUs. Seems pointless to fit a metal clad if it's got holes in the...

    What the B stands for in IPXXB...

    Bubble wrap. New Build, say no more. The armouring was connected at the other end. CPC via the 3rd core.

    CPC sizing in a conduit

    I was at the wholesalers today purchasing some 2.5mm singles to be installed in steel conduit and got to thinking. You can use the conduit as the CPC I know,  but the way I was taught and the way I've always done it is to install a CPC with a CSA matching that of the size of the Line...

    Big lamps

    The "small" one is 12kw. The large 20kw. Out of some Fresnel lamps.  The 20kw boasts 5.7M lumens, a life span of 350hours and a price tag of around a grand.  Both of these are busted.

    Cast conduit box lids.

    Are the cast lids still available for steel conduit boxes? Can't seem to find them anywhere. Im not talking about the very thin flimsy lids made from steel sheet that wholesalers seem to sell nowadays, I mean the old thick solid cast lids that would tighten and clamp down nicely onto the rubber...

    Got to love tenants.

    Extractor fans turned off (that's the oldest one in the book). Family home. Smoke alarms removed from their bases and nowhere to be seen, leaving the property without smoke detection, the landlord had the radio base interlinked smokes fitted before tenant moved in, the following makes this...

    testing before starting the job.

    Interested to know if most of you carry out any testing before you start the job you're there to do or just crack on and deal with any issues once they're found? Simple job today, convert a couple of existing 1 gang sockets to 2 gangs. Open circuit on cpc, spurs off spurs, grommets missing, a...

    Butchered

    Found these in some old photos, thought some of you on here might appreciate. Must be bout 10 years ago. This was a new consumer unit that had been done by an NIC approved domestic installer. We were called by the customer to check it out as the customer was a bit suspect on the guys work. We...

    Revision Question

    Thought I'd ask on here.  It's difficult (for me at least) to determine what they're actually asking.  If they're asking max volt drop for a distribution circuit it would be 5%, 11.5V so answer a) 11.5V But are they asking what the acceptable volt drop would be if you included the 5V they...

    Inverter supply to a motorhome

    I have been helping my partner's Dad wire up his motorhome.  He has been supplying kit and I've been fitting it.  The van is wired for electric hook up so the site feed comes into a 3 way board protected by an RCD then MCBs to the sockets around the van. There is a cable connecting the van...

    Plug top horror show

    Some of the delights I've come across recently, I'm sure most of you have seen similar. All of the below were in service on various pieces of kit. Some obviously not on RCD protected circuits.

    More of a Re-introduction

    Not been on here for around 6 years. I moved out of electrical installation work into temporary stuff, events, TV lighting etc. and lost touch with the forum. Stumbled upon the forum once again when having a look at current qualifications and what would be required to get me back up to date, a...

    3Phase To Single Phase

    Hi all. My understanding of 3phase with a neutral was that the neutral conductor carried any imbalance in load between the 3 phases. So would I be correct in thinking that with a device like this (32a 3phase input and 3x 32a single phase outputs) with a 32a 3 phase input you can safely pull...

    Transformer Telegraph Poles

    Just asking here on the off chance there are some over head linesmen members. There's an old redundant transformer stand mounted on twin telegraph poles that has a light attached over looking a car park that I've been up today to bolt the light up as it was only tied on previously with rope...

    Roller Shutter Door Safety Cutouts?

    Been to a job today, a commercial kitchen that has a roller shutter door between the kitchen and dining room serving hatch. The roller shutter door had stopped working altogether, they'd had a play with it and basically messed it up (going down with the up button and vice-versa, wouldn't...

    Interesting Setup

    A mate that lives a fair distance from me was asking some questions about his electrical installation, not being able to look at it in person I asked him to take some pictures, this is what I received... the supply... The other end of that cable... and coming out of the side of the CU...
