    Noise from fuse box

    Right I’ve woke this morning to notice the immersion isn’t working. It had tripped in the box when I put the trip switch back to the on position there is a noise coming from the box itself sounds like a buzzing noise wouldn’t say it’s a loud crackling noise though. It’s stressing me out.

    Blew The Fuse Connecting NEST to Mains

    Hello. Hopefully someone can help. My underfloor heating died recently (due to the heating mesh rather than the wiring) and I can't fix it without lifting the floor in the bathroom. So I have a useless control panel on the wall that I no longer can use and wanted to mount my Nest there...

    E39 530i touring - Nav fuse stray voltage on earth side - battery drain

    I have recently traced what I think is probably causing my battery drain to fuse 56 in the boot of my touring which is one of the navigation fuses. I thought could just pull the fuse to stop the drain as I never use the sat nav anyway but its had some other consequences. When I pull the fuse...

    Do I need an inline fuse between my alternator and battery isolator?

    I purchased a 95 amp battery isolator and my alternator pushes 95 amps but I'm assuming that it may spike above that occasionally. Should I put a fuse between the two? I am only aware of 100 amp maxi fuses would that save the isolator for damage or do I need to purchase a battery isolator rated...

    Wd40 and fuse boards.... Anybody tried it?

    Had the WD40 out earlier cleaning my fiancees bike up. Saw on the side they suggest it can be sprayed into mcbs on a fuse board. Can't say I have ever thought of that. I know it can be used on contacts but it somehow seems wrong to be spraying a liquid into a fuse board as shown on the can!

    Can I use this Time Delay Switch on a panel heater?

    Just a quick one! I believe this time delay switch should work for my old panel heater (1.25kwh) because it handles loads up to 16A. Can anyone confirm this for me? I had someone tell me I needed a fused spur switch but others tell me I don't. FYI: the aim is to ensure the panel heater turns...
