Yes, and don't tell them you have had the cut out apart, and don't do it again, the supply cable upstream is likely fused at circa 400A at the transformer fuseboard. So f***ing up or slipping would result in a very big bang indeed!

If its quite a sizeable gap between plasterboard and brickwork then a few loops of all round band screwed and plugged to the wall is another solution https://www.toolstation.com/all-purpose-fixing-band/p24536

You mean its a 3core cable with an approx 10mm overall diameter? You can find specification tables on manufacturer websites https://www.doncastercables.com/cables/6/26/SWA-and-Mains-Distribution/XLPE-Insulated--PVC-Bedded-and-Sheathed--Steel-Wire-Armoured-Cables/ But even 1.5mm² 3core is shown...

Can the readings obtained through the home mini be used for billing then? I was never sure, I did wonder if the mini was only to provide data to the app as an alternative to the IHD (when I had my smart meters done last august, I was offered IHD or mini), I didn't know if there was some...

1. If you envisage more than 63A feeds being needed, then best option is what the manufacturers often call a 'hybrid board' Hager and MEM do them, where you get a couple of TP ways at the bottom that are rated to 125A and taking physically larger breakers (each pole is 27mm rather than 18mm)...

As above, but you should also be aware that a lot of places use the term INSTALLATION TESTER as a synonym for multi-function tester see here for example: https://cpc.farnell.com/megger/mft1735/multifunction-tester-3-phase/dp/IN09209 , its not a term I particually like because it looks too much...

Nah, too busy thinking wondering about CFL lamps, vintage photography processes and the amount of relay logic that old jukeboxes and pinball machines had....:D

Thats why I shouldn't reply when I'm tired.... fixed

I think you'd best post a picture, Red and two blacks with no CPC would be a *very* unusual cable. A CPC has been required at every point since the 14th edition regulations came in in 1966, so a '73 house shouldn't have cable without one.

Theres also Julian date format. Nothing to do with Julian vs Geogorian Calenders, before someone brings up the orthadox church, or Russians missing the olympics..... CYYDDD Century being 0 for 1900s or 1 for 2000 YY being a two digit year and DDD being the day of the year. So today would be...

Looks like red FP used to supply the intruder alarm to me, very roughly installed, likely by the alarm guy! No - You're thinking of MCBS to fit in an old wylex standard unit, which provide overcurrent protection in a slightly more convienient way than re-wireable or cartridge fuses, they do...

Thats clearly a base from a zoned fire alarm system, not a domestic smoke detector, and it seems its been connected with break on the neg rather than pos. What fire panel is this on? (picture please) and what detector head have you removed and what are you replacing it with? I'm assuming this...

What supplier are you with? If octopus then see if you can get on tracker for gas, aside from a slight peak in the autumn mine has been hovering around 4p/kwh for gas over the last few months and I don't think the peak went as high as 7.5p. Obviously thats no guarentee of future performance, but...

You'll also need the correct connectors, generally the compression F connetcors are used, which require the correct tool, twist on F connectors will often work but generally arnt regarded as that good of a job

Yeah in a situation where no wheels have traction even with the brakes off them ABS is not able to do a thing, however I suppose there might be a a point where one or more of the wheels is able to regain traction if only the brakes were eased up a little

I seem to to remember that simply standing on the brakes without ABS operational will have you skid to a stop in a shorter distance than you'd stop with ABS preventing the skid. ABS gives you the ability to maintain directional control over slightly increased braking distances, which in most...

The point deducted only works if you are given a chance to justify ones that don't appear on the official list and have the examineer make a reasoned judgement. Because other than those boards having been poked and prodded to death, theres also likely things that fall through the gaps that are...

I'd not sure I'd agree, its quite a large circular base, so even if it is three plated there, a bit of time dressing the cables to lie flat against the ceiling while avoiding the threaded mounts from the spots should see it done without too much hassle. Depending on the nature of the new fitting...

Theres also the reality of finding (in commericial buildings) such dodgy equipment that has been through a round of PAT and now has a "Pass" sticker on it, presumbaly because the guy going it has been tought to plug it into the machine, press go and then look at what the screen says. Including...

Its not the best question in the world, an honest answer would be "defintaly *not* D" and you are on the right lines. With less than 10x In, you'll not hit the mag trip point on D curve (between 10-20x) so it will have to go out on the thermal trip which won't be as fast. Now you cannot...
