Here’s What You Need To Charge Your Electric Car At Home | Lrd12 Overload Relay

The third apartment I ever rented had ungrounded two-prong outlets in the kitchen, and rather than do the old 3-prong-adapter route for the microwave (the good ones with a green wire to the center screw), I said, “let’s replace the outlet,” I switched the breaker, verified that there was no power with a lamp, and started disassembly…. and the screwdriver arced, Most likely the breaker was on the neutral instead of the hot or something stupid like that. I did one of those “cat with octopus on his face” nope nope nopes, and *carefully* reassembled everything and fetched the darn 3-prong adapter.

I’ve paid 18’000.- CHF in Switzerland back in 2017 for a 9.3kW roof top installation and I’ve gotten 5’580.- CHF back from the Swiss government in cash. That’s like 13 cents per watt installed

Even though they are more expensive(dropped under 20 thought), you can already find the wifi version of this. Just search for wifi smart socket and you will find some.

I’ve been bit in a big way only three times. Two of the three were “Trust but don’t verify” issues, and I learned from them – always verify, no matter what anyone says.

Also, worth noting is that many cheap supplies out of China are designed for 110V/220V, +/- 10%. Consequently they’re designed to 121V/242V. For those of us in 240V areas, so in perfect conditions, they’re operating at the very top end of their specifications.

Using SO for internal wiring is something that I have often done — it is resilent, flexible, and high temperature. Also a joy to strip.

GFCI breakers aren’t usually used because they aren’t accessible to normal operators like a outlet mounted one would be.

It’s good to see a snubber on the design (that’s often omitted on DIY designs I’ve seen). There are a few TRIACs that are designed to commute highly-inductive loads (“snubberless” is the marketing term I’ve seen) — may worth looking into them to reduce the BOM.

2. At the 1.8V voltage drop Mattias Wandel mentioned in the video, his SSR was dissipating about 40 Watts of energy and the metal bast plate he mounted the SSR to was not sufficient for dissipating 40 Watts of heat energy.

Because a failure of the sort I have described will not be current limited. You’ll likely start a fire.

Dunning-Kruger effect. It’s impossible to correctly estimate your own stupidity. This is the cause behind half of everything wrong in the world. The other half is psychopaths in positions of power.
