    Unusual lighting wiring?

    Hi. Today I was at a friend's house having a look at a couple of lights that weren't working (turned out that quite simply one of the neutrals had worked its way free in the first rose). It was all too tight to see for definite, but I think the wiring was basically as per the drawing I have...

    Unusual light switch

    Hello, I wonder if anyone could help me with this unusual one-way light switch. I have changed light switches before as a DIYer but have never seen one with these markings. As you can see in the photos, there is no L1, COM etc, just 1, 2 & 4. Each number has two places for a wire. So, what goes...

    THWN vs UF-B in my unusual conduit installation

    Hello, I have 50 ft of corrugated pipe buried between my house and a pool shed. I placed it where I knew future landscaping would make it very difficult to do any trenching. It's four inches in diameter and about two feet down. So far I have pulled two direct burial cables through it, one for a...

    Unusual singles from Batt Cables

    I was working with some odd singles today from Batt Cables, they seemed to have a plastic like braid between the insulation and the copper, almost as if it's some kind of fire rated cable, I don't believe it was LS either, it was a bit of a pita to get rid of the braid and my prysmian rolls...

    Unusual Neutral Tail into Consumer Unit

    Hi, Ignoring the appauling conductor terminations which I found, in the background of the photo you can see a really odd neutral tail terminated into the main switch. I've never seen this before, has anyone else, and if so what is it ? Oh I should add this is at a flat, so the tails are...

    Unusual combined light switch/dimmer

    The house I've just moved into is fitted with the light switches shown in the pics. They are fitted to each bedroom and the landing. The landing light is also switched from a second standard switch on the landing as well as a standard switch in the hall. So essentially 3 way switching. I can't...

    I have 2 kitchen lights, each on its own switch. I would like to re-wire them to where the first switch turns on both lights, but where if the first switch is in the off position, the first light goes off but then the second switch can nevertheless turn on and off the second light. I have a...

    Unusual Ring Final Tests

    After fixing a few CPC related issues on a ring final I got the following results L-L = 0.47 N-N = 0.47 CPC-CPC = 0.69 R1+R2 Tested at 0.31 R1+Rn Tested at 0.25 All looks good, until that is I realised that the CPC-CPC is actually not quite right. It should be 0.78 (0.47 x 1.67 for a 2.5/1.5...

    Hi, I have a customer with a Storad SR140-3 storage heater (in the bathroom), which does not work. The resistance of the elements is ok. There does not appear to be any onboard controls but situated outside the bathroom door is the charge controller (I think). I have never seen one like this...

    Unusual 2 way switching.

    Hi, Hopefully a quick and easy question. I have just installed lights in my loft and everything is work without problem. However, I am a little paranoid about leaving the lights on up there and when closed up you can not see that they are on and it could be months before this is discovered...

    T5 8W tubes - unusual failure rate - is it the tubes?

    The lighting on my boat includes about thirty T5 8W 12" tubes in conventional 12V fittings of good make (mainly Labcraft) with HF inverters, taking one, two or three tubes as required. For over 25 years these have worked more or less flawlessly; the only outright failure was when water got into...
