AFCI circuit breakers and the problem of ‘nuisance tripping’ | 220v Contactor Relay

You now have a Tesla 3 correct? What is the efficiency hit by using 120 volts? It used to be a 30% hit for the S,X, Roadster, and new Rav4Ev with the Tesla drivetrain, Meanwhile 12 amps at 115 for a VOLT is quite efficient.

The only people having trouble with L1 are those DOPES who haven’t read their owner’s manuals. There all EV manuals state that car charging is a heavy continuous load, and it requires high-quality receptacles that have been tested to make sure they are safe by someone competent.

It’s a 750W pump. Since it is running on 220V, steady current would be ~3.5A, so inrush current could be as high as 20A, according to some sites I’ve just found. Doesn’t sound awesome.

A residual current circuit breaker. Jimbob82 [Public domain], via Wikimedia CommonsA residual current circuit breaker compares the current flowing in the live mains conductor with that flowing in the neutral. In a normal situation these currents will be identical as current flowing out one must flow back in the other. If they differ, it is likely that the missing current is due to a hazard or fault, and the circuit breaker is activated. So if the power shorts to earth through your body rather than the normal return path, it is detected and cut off. It is important to understand that a residual current circuit breaker will not protect you from circuits on the other side of an isolation transformer, however this is to provide some protection for the other circuits on your bench. You may well find that the wiring codes in your country mean you already have a residual current circuit breaker in place.

The other advantage is, if your system needs to go into debugging, you can still use the included remote for a manual override. AKA your family won’t kick you out of the house and never let you bring an invention inside again.

Like many things, it’s the few psychopaths who spoil it for the rest. For most people, it’s quite possibly an emotional disability.

And for the record, If I’m able to, I will breastfeed my children, because nutritional value, probiotics, and antibodies.

I’m certainly pleased the US Air Force along with the wind turbine industry taught me just a few skill sets in getting that Level 2 service expeditiously installed.

Oversizing switching gear is good to some point but instead of relay withstanding surges I would prefer breaker that would protect everything.

There is no mention of what powers the module here, and I suspect it is a regular 5V, isolated SMPS. @RobHeffo suggests transformerless power supply, but that is not a good idea, for the current drawn by the ESP the capacitor will be too big. There are alternatives, like this guy, LNK306 : http://www.mouser.com/ds/2/328/lnk302_304-306-179954.pdf . It is not isolated, but the thing is probably the best cost option for such a device.

Image sensor and processor. Of course, the image sensor and processor are also an important part of the speed and image quality of the Sony A33. The Sony SLT-A33 has a newly developed Exmor APS HD CMOS sensor, which has a total resolution of 14.6 megapixels, and an effective resolution of 14.2 megapixels. That’s just slightly below the 16.7 megapixel total resolution of the A55, which yields its effective resolution of 16.2 megapixels.

In product safety standards all exposed metal parts are “Bonded” to earth grounded. This is so that if an internal line voltage wire was to contact exposed metal parts the circuit breaker would immediately trip and turn off the circuit. Without Earth ground YOU would be a fuse that completes the circuit.
