What to Consider When Buying and Installing a Home Electric Vehicle Charging Station | 220v Contactor Relay

I suppose a more flexible grid, with more cheap gas plants, which can fire up quickly, made this possible, as well as making the grid itself smarter. There was a rush to build gas power plants a while ago, since of course gas isn’t going to run out any time soon or anything.

Whether you call it neutral or ground is (I suppose) not important, what is important is that there is no distinction between neutral and ground until you are at the customer’s meter.

I stuck a finger in a light socket when I was about 3 years old back in Brooklyn NY and got a momentary buzz sensation. Nothing more. I got a few more 110V shocks as a US Army Air Force student of electronics back in 1944. No problems but I was warned to keep my left hand in my pocket in uncertain situations to not form a circuit through my heart, Here in Helsinki where I now live I have taken 220 V a couple of times. Nothing I’d recommend but no harm done. Nevertheless, I’m careful and never fool around with wet hands.

Technically it depends on the amount of resistance, effectively proportional to the amount of the conductor the electricity is able to pass through. With AC that means the skin effect comes into play but that’s a whole other bundle of fun math. With DC it’s essentially amps times volts.

WASHOUGAL — To hear Shirley Scott tell it, this town’s recent drive toward proliferating public artworks was born out of…

Such an awful practice and terrible idea. I have an EV and would never do this (me being an EE). I decided to make this correctly and I installed dedicated #10 cable from the auxiliary power distribution box to the EV charger as a permanent connection, no plugs no unsafe contraptions, and following all the NEC codes. Those cables you used and the crimp terminals aren’t suited for the current rate. Check them if you don’t believe me. Crimp pressure plug in terminals are rated for around 6 amps of continuous AC current and I hope you used at least 600 A.C. volts insulation cable… Bad, bad idea.

HOWEVER: these are NOT 180 degrees out of phase. It is more like 120 degrees. I am taking it that America also has 3 phase supplies, rather than 2.

When the cycling control opens, line voltage is taken away from the motor. The motor’s rotor decreases in speed. Thus, the back-EMF generated across the start winding decreases in magnitude. The relay’s coil now sees a lower back-EMF and no longer can generate enough magnetism in its iron core to keep contacts 1 and 2 open.

To tout that you’re rigorous about tracking efficiency data, you completely missed a very important statistic.

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.
