    What's the best way to ground a Jackery Explorer 2000 Pro power bank ?

    Hello. We have a Jackery Explorer 2000 Pro power bank. It has 2 x AC outlets. When it's switched on, it creates a lot of electrical interference with wireless devices, such as DAB radios ...etc, no matter where they are in the house. It knocks them out and they can't get a signal. There doesn't...

    Day 3 - So what's that bit for?

The generator output is usually around 21kV. National Grid distribute at either 275kV or 400kV. DNOs go up...

    What's happened to the 'polls' option?

    I was trying to start a new thread today, with a poll. I can't seem to find the option though. Has it been taken away? Polls are fun! Also, I notice on other threads that had polls, I can no longer see the poll... What is your hourly rate as a self employed electrician? (2023) | on Free...

    What's next to my board?

    Evening all, I'm relatively new to the trade and have just moved house. Looking to rewire and was looking at a few things, could someone tell me what on earth is next to my board? From what I can see is it looks like two contactors? But what are they likely to do?

    What's the problem?

    Hello, The CUR6330a keeps tripping, even when no sockets are turned on. The issue is the "sockets" switch though - it's the "sockets" switch that trips the CUR6330a switch. A few weeks ago, I had this problem but I thought I had found the faulty socket and the problem was somewhat resolved (by...

    What's wrong with my MR16 LED Light Bulbs, GU5.3?

    This is the second set which won't work to replace the current spots here in my kitchen. All they do is flash once quickly. I'm replacing standard older halogen and wanted to use LEDs but for some reason this is still happening. I've looked above the kitchen unit and can see a transformer? Is...

    What's the Banjo doing?

    As a trainee can I ask why the banjo is on the outside of the Wiska box. I understand that the earthing of the SWA must be maintained but would having the banjo outside mean you need to drill through the IP66 box to connect to earth and by doing that are you not compromising the IP rating? I...

    What's the point of DIN rail terminal blocks?

    I keep seeing these on pics of installations, mostly industrial, and just wonder what they're for? Are they fused? Why put one in when we can go straight to the breaker instead?

    If a type B MCB doesn't trip unless 5x nominal rating is hit, what's to stop the cable burning up?

    Just reading through my Student's Guide and wondering about nominal amperage. If guaranteed trip is 5x nominal amperage, what's to stop 2.5mm cable on a 20a radial circuit from running at 70a or something and completely destroying the cable/potentially your house?

    What's the best way to soften/darken harsh office LED lights?

    Not an electrical question, but hopefully someone can help... I work full-time in a small office, where the LED lighting is horrible. It's three overhead square fittings (each 21" x 21" or thereabouts). They can't be dimmed and the light is intensely cold/harsh/eye-strain-inducing. I'm looking...

    What's going on here?

    Hello - see attached photos of the downlight fitting in my bathroom. In short, the consumer unit recently started tripping, and on investigating I found a scorched cable, which seems to have been resting on the uncovered incandescent GU10 lamp, the heat from which eventually burnt through the...
