    Immersion heater wiring

    It's white round cable, I'm guessing 1.5mm2 and it looks the same as the heat-resistant cable I had on the heater in my last house. Cheers

    Immersion heater wiring

    I've recently moved into a house and would like to check please whether an immersion heater that looks recently fitted has been correctly wired. It's rated at 3Kw and is wired with 2.5mm2 cable from a 16a MCB. The isolator switch is embossed 'immersion heater' and matches the images of 20a...

    UK Live for one cable connected to the neutral of an adjacent cable?

    It appears a sparks has connected the live of one lighting circuit cable to the neutral of an adjacent cable using a cable connector in order to obtain a power supply? The circuit has worked fine for 2 or 3 years but has now failed. While the cable triggers the NCV there is no current or...

    It alre It already is! So looking at solar panels too.........(pricey!)

    Potential overload of ring mains

    Yes, take your point - I've lodged an enquiry with Power Networks as to feasibility. No I hadn't thought of LPG boiler - funnily enough there was an old one here when we moved in which wasn't in use and we had it removed. Issue here really is the space required for tanks/boiler, but it's worth...

    Potential overload of ring mains

    Understood - is a 3-ph an essential part of the solution? You can get 15Kw single phase pool heaters I'm told.

    Potential overload of ring mains

    Next issue - even in this weather, with electric heaters on a lot, no tripping at all. But - we are looking at heating the pool, which would take at least 15Kw elec heater (no gas/oil). There is a 60a supply (single phase) to pool house which drives pump and heat exchanger (which apparently only...

    Potential overload of ring mains

    Can't find a Flexiclamp 200 anywhere, even Ebay. I guess one might come up sometime, in the meantime I'll go for the cheapo Amazon one - thanks Taylortwocities for the advice re ohter influences

    Potential overload of ring mains

    Thanks again for the suggestions, I'll have a look at the Flexiclamp. Yes that's right about the 'efficiency' claims. I got the impression that Haverland were suggesting they could produce more heat per amp, but how you would measure that I'm not sure, without some sort of comparison. They...

    Potential overload of ring mains

    Thanks for the suggestions, some good ones there. CU might be the best bet, though space is a little limited. I also thought you needed to avoid close proximity to other conductors as that might affect the magnetic field. I'll go for the cheap clamp meter off Amazon and experiment - though as I...

    OK, thanks for your help.

    Potential overload of ring mains

    I hadn't thought about the sockets - presumably you'd need a plug-in module with split cables attached? Cheers

    Potential overload of ring mains

    Maybe the idea is a flexible adapter, a hoop you can unplug and pass behind the conductor and then re-plug, pushing the banana plugs at the other end of the adapter into your multimeter. Not cheap at £100+ though.
