    EICR. Cu "armoured" 3Ph supply cable. Is this a thing?

    I've come across a DNO installed (SSEN) 3 Ph 3 core PNE supply cable from a private substation to a large Lucy domestic head. Cable 3 Ph is copper "armoured" (or is there a better name for it?). Entirely underground, entirely within a domestic single owner property. No obvious practical or...

    Please suggest a reasonable quality white euro-module brand

    I don't do much data cabling. I fitted recently CAT6 using TLC budget "Kauden" brand euro modules and plates. No problems with the module connectivity, but they were sloppy in the default frames and the frames were really flimsy and nasty sharp cornered thin plastic. I needed a lot of care just...

    slim 6mm SWA Y joint for bollards?

    Terminating 2 x 6mm swa into 1.5mm H07 flex inside lighting pillars. Many of them.. Max probably 85mm dia. Wiska 308 too big, Wago capsule too big, Galv trouser boxes too small. Nothing seems to be suitable. Am thinking of making my own with 82 dia solvent weld tube. - Know of any commercial...

    High CRI GLS bulbs. Not costing a fortune?

    Does anyone source reliable and good value high CRI led bulbs in standard GLS format (ES & BC)? - Ones which don't cost a fortune and give out good ~2700..3000K light? I have found that the fairly easily available and not too pricey Philips CRI97 "ExpertColour" GU10's make a really noticeable...

    Hager part KRN190 neutral connecting block

    Who's familiar with Hager KRN190? It's called a "neutral connecting block" by Hager with no further info. This seems a maybe misnomer, but I have never seen one in the flesh.. I'm assuming it would have a lower terminal spaced to fit a standard Hager busbar prong if it were fitted like an MCB...

    Recommend a IP65 consumer unit please.

    Could someone recommend me a 7 unit wide (minimum) IP65 consumer unit? Plastic is OK, - it's for a horticultural site in a polytunnel. I find Garo, Protek, any others? (Looks like I'll have to populate it anyway with A.N. Other breakers and parts). I want want robust enough to take several...

    Best value fused switch plus 2 module type 2 SPD?

    Has anyone done this yet on a budget? I'm pricing a job to run a submain off a TN-S. I'll need a fused switch incorporating SPD alongside in the same enclosure. Price sensitive. Thinking of a budget Lewden off the shelf fused switch (in 4 module enclosure), ditching the enclosure and buying 6...

    Black PVC/conduit back boxes. - Source?

    I need black surface back boxes. PVC or ABS conduit boxes would be fine, as would metalclad, but not the crunchy ones. - There will be some conduits involved. I can find only Wickes (who sell a single outlet black box only, no doubles), same at CPC. Occasional Ebay sellers do have some with...

    Use of FP200. Will it get messed up by too much flexing?

    I have electrics to add in a listed barn. It's a unlined shell of a building, grubby cobwebby beams and timbers with external claddding. Customer must have all black wiring so as to hide it as much as possible. Everything will be clipped with metal accessories. Trunking/conduits are too big and...

    Quinetic wireless switches sold by TLC. Any experience of them?

    Who's used these, and got any practical experience of range performance when there's a wall/window in the way? (FYI the transmitters don't use a battery, but get their energy by giving a big thwack to a lump of piezo). Having many years in radio electronics, I'm well enough aware that...

    No service head fuse?

    So I was at a 2 bed flat today, ground floor on 4 storey block. 3 years old flats. The supply head holds a red fuse holder reading " solid link, do not fuse". TN-S and the CU is just off the bottom of this shot below the 100A isolator. ~75 cm tails. "Fuse" is all crimp sealed, I didn't pull...

    A bakelite half-moon box :)

    Funny little half-moon bakelite box hidden behind this wall. Quaint, wonder what the thinking was for those. Have not come across them before.

    PV non MCS wow.

    I am undertaking EICR at a sprawling domestic over a house and several barns/guest suites, which is knee deep in C2 and C1 observations. I have here a ground-mounted PV install without any documentation, not an MCS install, and (I just spoke to DNO), they have no record of it on G59 or G83 and...

    MFT1700 series wandering zero problems fixed.

    Here's a tip for anyone still using an old MFT1700 series tester. Mine dates from 2012. I found about three years in - by 2015 in this case, that the zeroing of the leads on my MFT1720 was becoming increasingly random and the zero would wander about by a fraction of an ohm which became...

    Green OK light in emergency bulkhead lamps.

    To speed me along with a quote since this is all taking too long and I haven't taken a penny yet. Q) Would a modern LED bulkhead emergency light have a green indicator LED for any reason other than proving that it's a "self test" type in working condition? (In other words do non-self-test EM...

    Passive TV splitter inside back box?

    OK, this should be easy for someone. Firstly, let's assume a strong enough signal to take passive TV splitter at the bottom end of the cable from conventional aerial. Is it reasonable then, to take an existing single TV outlet in a standard inset wall metal back box with front TV socket plate...

    Does 1mm SWA exist?

    I was on a domestic site the other day in the pitch dark, surveying for a customer who has a skinny 4 core SWA laid to their shed already and now wants a 13A socket. It was not possible to make out the cable embossed markings since they were underground, but my vernier caliper on a single strand...
