Turn a wall outlet into a wireless charger with the Legrand Radiant | Circuit Breaker Parts

The most useful thing I found in this article is that you can rotate those screw connectors at a 45 and they drop in 0.1 inch breadboard holes.

Dumb question but in wiring up a bench setup as described – in what order should the isolation transformer, RCD and isolator switch be connected up. RCD on mains side of transformer along with isolator? Double pole isolator for live and neutral? Maybe add a suggested circuit diagram to the excellent article and improve readership safety even more.

I have pulled this hack in a pinch with specific pieces of test equipment, etc. (usually large power supplies) in non-residential settings but instead of having a snazzy box I would use one extension cord and my trusty Fluke and sort it out. In that application, the circuits were almost always dedicated (or near-dedicated), but in a residential setting, there are still many circuits that are rarely loaded much if at all, and I see this as working perfectly fine for those times.

Washing machines etc. have their own 10-16A fuses. 3 phase 16A power is used for larger equipment, most commonly for semi-permanent installation like oven&stove combo and electric sauna stove. Those are usually connected to star, so single element in equipment will still see 230V.

It’s the other way around. Muscles and nerves respond to di/dt and not constant current. You can let go of DC but not AC because the continuous pulsing is how the nerves signal the muscle to contract.

One of the best demonstrations I’ve ever seen, was at the Dayton hamvention. DP&L (Dayton Power & Light) set up several short poles with standard 7200 to 220 center tap transformers. By back feeding the secondaries with 220 from the breaker box, they could energize the 7200 lines and began demonstration what happens when you encounter these wires with numerous items. Antenna masts, kite strings, and even a hot dog were used to show the immense power available, and the audience was always suitably impressed.

I’m renovating my basement, and putting in a 240V line to my garage. Just for something to do, as I don’t have an EV.

I’ve spent four to eight years in apprentice school learning how to plan, install, inspect, and repair electrical products. Don’t insult my intelligence by implying otherwise.

That’s how you may get some serious, even life-threatening, internal RF burns without noticing anything.

The more you think about this the more you realise that there is actually no truly bomb proof way to organise it but the methods now being implemented are probably about the safest way for most situations.

The importance of inspection isn’t so much the wires popping off as heating up. Any signs of discoloration of the crimp terminals or wires, or any fog or smoke and you should disconnect *everything* immediately and stop using it until or unless it is repaired and ALL heat damaged components replaced and THROWN AWAY.

​So if I am looking to make the magnet more powerful, other than supplying more current, could I wire the primary and secondary coils of the microwave transformer together in series to get more turns (being mindful to keep the direction the current flows the same in both coils)? My thoughts are that it would increase the resistance a bit from the added wire but that the magnet would have a lot more turns. Am I missing something or am I onto something? Thanks in advance!
