Things Your Electrician Wishes You Knew | 19mm Momentary Push Button
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. A big oversight is that outlets are frequently wired backwards with the live and neutral switched. The outlets could be tested first but that kind of defeats the purpose of this t...Read more -
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 ...Read more -
Charting the S&P 500’s range-bound, but bullish, (unofficial) summer start | 19mm Momentary Push Button
My original quote is based on the project you called me in for. If I find out there’s actually a larger issue at hand, I’ll need to increase my price to match the scope of the project. I’m not ripping you off, I’m just making sure I get compensated for the extra work. True, but I have never seen ...Read more -
Xiaomi Mi Mix 3 announced: specs, features, price | Lrd12 Overload Relay
But Mike I would gladly clean under your stove for around 3kW of free power… Ahh ok so his parent’s don’t have a 220/240 outlet, makes much more sense now.

It turns out that the live viewfinder image doesn’t cover the full screen in 3:2 aspect mode, but is normally confined to roughly the central 80% of the available display area. When you switch to the Fn menu display, though, you need to press your eye pretty close to the viewfinder eyepiece...Read more -
The Expanse is being turned into an RPG | Lrd12 Overload Relay
I think a lot of the negativity is par for the course on Hackaday when dealing with HV (or other areas with safety concerns) projects. I got my share of the same thing with my “Quick 220 clone” project. Such projects should garner a healthy dose of paranoia, but I think where it goes wrong is whe...Read more -
Looking Mains Voltage In The Eye And Surviving | 25 Amp Circuit Breaker
I suppose the other point of note is that compared to 220/230/240 Euro voltages, residential 240 is not 240 to ground. The only things that have such high voltages to ground are either corner-grounded 240 deltas (which are exceedingly rare) and 480/277Y systems (which admittedly I do a lot of wor...Read more -
Who’s really being silenced on Twitter? | 220v Contactor Relay
Back in the day the UK before EU harmonisation the nominal single phase domestic voltage was 240V ac and within a range of +10% and -6% ie 264V and 225.6 V Under EU harmonisation it is 230V +10% and -6% ie 256 V and 216.2 V. I can assure you that voltage control at Primary substations in the UK 3...Read more
