    New garden room - certification needed?

    If the name or logo appears on any paperwork, van etc, showing the name of any scheme provider like NICEIC then it is down to the electrician to notify LABC, otherwise it is down to the homeowner, and I have also thought this is a silly rule, as most people are not looking for NICEIC logos, they...

    Does this immersion require an RCD?

    It seems there is a bridge rectifier in the iboost, and a large switching device, so it does seem the output is pulsed DC. Watching a video on one being repaired was what showed me output is pulsed DC. I have a problem with type A rather than type AC RCD's as other than EV charging units, there...

    Does this immersion require an RCD?

    I have wondered with my own immersion heater if the type AC RCBO should have been changed, but with little chance of anything touching a live part, not really worried, more worried as to if the thermostat is rated for the supply. I know the immersion heater uses DC, but assume a pulsed DC? But...

    RCD's

    It is after 2008, but I wonder how one would do it with TT, so wonder if there is something missing, I have when doing a word hunt, ending up with something out of context.

    RCD's

    Since BS 7671 is not law but can be used in a court of law, hard to say any regulation has to be legally followed, specially since it says in the intro to BS7671 that wiring complying to a previous edition is not necessary dangerous. The main problem with RCD's is the changes in 2008 allowing...

    Smart Switch 2 gang wiring help

    It seems unlikely there will be a problem linking to neutral in your case, however in general one has to be careful, the 4 gang light switch by my front door, has two independent supplies at 230 volts, and also an extra low voltage supply. Before buying the house, someone had got the neutrals...

    Storage heaters and Radio Teleswitch Service (RTS)

    There are loads of people who still have an old time clock, it does not need to be linked to some wireless system that turns it on and off. The press release explains and it says but there are other methods, if the smart meter does not work in the area you are in, they need to use a different...

    Boiler Tripped RCD

    There are some things with older boilers which could cause an RCD to trip with no fault. But in the main the modern boiler is designed to have an RCD, so will not have any spark igniters likely to cause it to trip. So we have to test, we can to an extent use trial and error, but if that fails...

    skills an electrical improver needs

    An electrician cover a massive range, and we tend to specialise. Even within a specialisation, we can go further. When I worked in manufacturing, the PLC was king, often the first tool out of the bag was the laptop. Where with installation often what it looked like was important, not marking a...

    Battery Solar/Inverter/Battery setup?

    As he said, once set up correctly, the customer should not need to touch it. He did say Octopus Go and with Octopus Go the payment for export during the day is more than charged for import overnight, so the unit to divert solar into domestic hot water is pointless, as he will save more money...

    Adverts making forum unusable. Half my screen is filled with adverts.

    This is simply not good enough, to try and work with such a small window, sorry, unless this changes, this forum is dead as far as I am conserned.

    Wireless Light Switches

    As far as I am aware, the TP-Link (Tapo) smart switch will still work with no 230 volt power, but not really tried it, but seems likely as battery powered. Not sure about relays, bulbs normally default on. So a short power cut and all the lights go on. So having a switch to turn them off when...
