    How to shut off 120v baseboard heater? Double pole wall mount thermostat? Single pole wall switch before heater with onboard single pole therm?

    I've planned a 20A circuit serving a tiny half-bath in a workshop. The circuit will contain a few LED ceiling lights, a receptacle (not for tools) and a 350 or 400W 120V baseboard heater. So it would not be convenient to shut off the heater via the main panel. When I'm not working during the...

    Came across some cable I haven't seen before

    I came across some cable today I haven't seen before. It has some sort of tough, inflexible pvc type sheathing (definitely not rubber). It's quite a light silvery grey and more oval shaped than modern flat T&E. Rubber insulation. No CPC. Probably tinned copper conductors, but maybe even...

    Isolator before the meter

    I wish to find out what’s people’s thoughts on isolators before the meter? Typically they are installed after the meter and before the CU, but does anyone know if there is any reason why it cannot be placed before the meter? Aside from what revenue protection like or not, is there any legal or...

    Commercial Sometimes you have to laugh before you cry

    Got a call from a beauty salon to ask if I repair electronic beds. I said no but the very camp voice begged me and told me no one would repair it apart from the German makers - and they wanted a fortune. He badgered me until I said I would come have a look. I've never been in such a place like...

    I have underfloor heating rated at 3kW. The circuit goes through a fused switch with a 13A fuse in it. That is supplied directly from the main fuse box with a B16 circuit breaker dedicated to that circuit alone. Every time we use the system, it warms up for a bit, then the circuit breaker goes...

    I've been doing quite a lot of work in a nice house for the last 3 days, bought by a retired lady and her son last Autumn and I was recommended after they'd had a N####C A/C in a few months ago.

    Something else to disconnect before testing...

    First came double sockets with integrated USB outlet, now BG has a double socket with USB and a built in wifi repeater. I think i'll just stop using 500v dc across L & N completely. I'm now waiting for double socket with integrated toilet roll holder.
