    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 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...

    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...

    An unusual electrical fault to find.

    I work in a large public services building near my home town and it consists of wiring that was done back in the 1950's (perhaps 12/13th Edition?) when the first buildings were erected using V.I.R. cables right up to the latest 18th Edition wiring that includes "phase matched UPS/IPS" systems...

    Unusual Two-Way Wiring

    I'm in need of some help in moving a ceiling light. I'm not a qualified house electrician, but I am a retired electronics engineer, so I understand the precautions. I thought it would be a simple enough job to disconnect the old fitting and extend the wiring to the new position. However on...
