    Electrial Rf interference, theory and practice of using Ferrite Ring Cores 'choke'

    I appreciate that @mark641 asked how ferrite cores work here, answered by @Lucien Nunes , but TBH, it is at a deeper level than I need. My question is more so in regard to the practical use of them. I (unfortunately) bought a Road Angel Halo Pro dashcam ...I bet you can already guess the...

    Can you help me install a fixture using a screw terminal block?

    I have never installed a fixture that uses a screw terminal block before and could use some guidance. Since the earth wire is connected to I screw the grounding wire in the same terminal and then connect the blue wire to the white and the brown to the black?

    Backup Generator using RV power outlet

    I currently have a 100 amp sub panel for a 50 amp RV hookup (on a 60 amp breaker). This is about 100ft from the main with 2/4 wiring. Would a 12000w generator plugged into RV hookup power the house? I think the issue would be limited amps so I could only run one of the following at a time: 1)...

    Wire an auto switch using two feeds.

    I registered as a DIY because it looked like the best option for my situation but am not really a DIY because I always hire an electrician so I will not be doing the work, however my electrician did not know how this could be done. She is extremely busy so I said I would check on the internet...

    Electrifying my tractor Shed and using proper gauge wire

    I'm installing a towel warmer and I thought I would include an outlet on the same cable because the towel warmer needs a junction box anyway. Can I run a 12/3 with both black/red hot, black attached to the switch, to the outlet connected to red, and continue the black to the towel warmer with...

    Flickering lights (am I using the correct thickness of wire?)

    Using a tuturial from a college lecturer, I've installed 2 way lights in our hallway. The cable I've used is 1mm lighting flex (2 core). The process I've used is taking the power to the switch. So I've used the permanent line from a neighbouring switch (4 gang) and connecting this to L2 where it...

    Using solar panel DC output to feed immersion heater?

    Just an idle thought - has anyone any experience of using the DC output of solar panels to directly feed an immersion heater, to avoid the expense and losses associated with an inverter?
