    SELV garden spike lights

    Have a look online, but you can get GU10s and even E27 and B22 in low voltage, I have used them in the past for outside lights and on canal boats. Most are sold in 12v or 24v, if you go with 24v the current will be slightly less

    How good is underfloor heating in a large room

    I have electric underfloor heating in my consventory and bathroom, Both I installed using the heating element wire on a roll rather than matts, but i believe the matts are the same thing just the wire is already nicely spaced for you The underfloor heating in my bathroom works very well...

    Yes in his case mains pressure cylinder probably would be the best option

    RCDs, 100A vs 80A vs 63A

    I have often thought how stupid it is to have a split board with say 63a RCDs and a 100a main fuse In my opinion diversity is not a good solution as yes the likelihood of overload is low, but if one day the heating packs up and they plug in loads of electic heaters, switch immersion on, and...

    Shower replaced by plumber blows fuse

    I have fitted an electric shower in my house, no gas only electric, problem is hot water tank is only big enough for 1 bath or shower, and cannot get a bigger tank in due to space restrictions, so as soon as the other half has had a bath no more hot water ,and i heat the tank over night on...

    Open PEN solution

    And there is the risk of your electrodes being to close to other PME electrodes or buried services in the ground and then PEN fault appearing on your electrode, but i guess if it was done at the point the foundations where done and to every house on an estate its almost like making a very...

    Open PEN solution

    I like the idea as I still struggle as to why we live with this risk of open PEN conductors, yes we mitigate by doing PME and inside an equipotential zone you will probably be ok (although people who have received a shock standing on an "insulated wooded floorboard might disagree). Yes why...

    Aftermarket remote central locking on Corsa D

    Ahh I see, the is probably CANBUS, So as you say it would be a digital signal on the one wire, I would still contact hawk as they probably do a new model which works for that system The system you brought from eBay sound like the old/traditional method which is 12v + & - to drive door...

    Aftermarket remote central locking on Corsa D

    Iv fitted aftermarket central locking to a corsa B and to a corsa (combo) C The combo C already had solenoids in the doors and I brought a unit from hawk (hawkcaralarm.com) which was made to work with the exsisting wiring and solenoids and switches, Hawk were very good I emailed them and...

    Multifunctional Testers - Which one have you got and how long has it lasted?

    Fluke 1662, Does me very well, probably doesnt do as much testing as some on here do, but when I am working i does a bear minimum of high current and no trip loop impedance test every day Alot say they like the fluke case, the hindge broke in no time on mine and i dont rate it that much...

    Why is a too high zs reading on a circuit okay if it’s protected by an Rcd?

    Interesting, A while ago I had conduit CPC fail on 2 circuits with 50-150ohm Zs, I pulled through a new CPC for one of them, and for the cooker ran a new bit of T&E as was close to CU. Although I believe this is the best way to fix it as now has a nice low Zs and meets disconnection time...

    Get a shock when you touch sink and oven at same time??

    I would also isolate the power to the oven by switching the breaker off / removing the fuse in the consumer unit / fuse box, until an electrican has been to check out the fault

    Boiler for static caravan - no earth

    As mentioned above the generator probably doesn't have L-N linked , Iv owned a few small (under 15 KVA) generators and all of them have not had a L-N link. The earthing point on the chassis of the generator just connects to the cpc/earth pins of the outlets, The earth in this case is...

    UK synchronisation of storage heaters and Economy 7 supply timings.

    I wouldn't opt for a smart meter. I too use economy 7 and if I get a smart meter the economy 7 equivalent i will be given is terrible, 9p pew kwh off peak, 18p per kwh normal and 35p per kwh "Peak" (between 5pm - 7pm) currently i have 9p off peak and 18p peak So check with your electricity...

    Earthing a cast iron pipe man light

    Very nice I had the same conundrum as you with a wall lamp I made using a trombone I couldn't find a suitable place to attach and earth easily and without affecting the look So instead I used a SELV transform and a 12v light bulb, depending on your bulb fitting this could be an option for you

    Should we really be working in peoples homes in Tier 3

    By you wearing a face covering you are stopping you breathing out covid into someone's house, but there is no protection for you catching it while in someone's house which may have it, as they will not be living in there house with a mask on so the air would be contaminated so to speak (the...

    Off the gas grid ...

    I think heat pump are the way it will be going, air source or ground source. The price to buy them is already falling alot and with gas being phased out more manufacturers could pop up and prices fall. In a heat pump some electricity is used to run a compressor some valves and control gear...

    YouTube electricians

    You cannot test r1 r2 with a multimeter as the resolution of the meter is normally not high enough and nor is the test current used from the meter You can also not test Ze & Zs, insulation resistance or RCD disconnection times, these tests are quite basic for small electrical work and are...
