I'm looking to remove a redundant electric fireplace heater - it's wired into a switched fused spur on the wall, which won't be used again after the heater's removed.

    Clicking/popping sound coming from wall when tv switched on

    Hi, looking for some advice.. the wall behind my tv makes clicking/popping noises when my tv is switched on and again when it’s switched off. It’s similar to the noise TVs make when they’re heating up/cooling. Don’t want the electrician to have a wasted visit if it’s nothing?

    Dimmed pir and switched line to single bathroom light

    I design bathrooms and I'm wondering if it's possible to use the same ceiling lights supplied by both a manual switch and a flush ceiling pir going through a concealed dimmer as a night light.

    Why does RCD trip when fused spur switched on

    I was called out last night to an RCD trip issue. I found that switching on the fused spur to the washing machine would cause the trip & I could only reset the RCD after switching it off. Straightforward up to that point, but after unplugging the washing machine, then disconnecting the spur...

    Switched mode power supply vs led driver.

    This might be a silly question and after 20 years doing this I probably should know the answer, but can a switched mode power supply and an led driver be the same thing? Example: I had a job the other day and I got a ‘while you’re here request’. Customer has a couple of 12v deadbolts to lock...
