Yes, the Samsung Galaxy S9 has a headphone jack | 220v Contactor Relay

WIRE CONTACTOR: A wire and contactor displaying the 90°C rating on the wire and 75°C rating on the contactor (when properly torqued).

Not always, you have to think on a global scope here before saying generalizations! In the UK a lot of houses are on what they call PME or protected multiple earths, where the earth bond goes back to the substation as a extra conductor. If you are in one of these properties and are not aware of it, and have your own ground system or leakage you can end up being lower impedance than the substation ground and grounding out faults in your neighbors properties which are also on the same bond. Where I am in europe, all the houses are individually bonded to their own low impedance earth, and the inspector comes out with a megga tester and tests its impedance before they will sign you off to connect to the public supply. It has to be below 50ohms total from any gnd pin on any socket in the property I remember from my inspection. I laid a load of mesh subfloor before pouring the floor so I had no problems with meeting spec. A nice low impedance earth will make your rcd and protection devices even more sensitive also.

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

The QD terminals I buy are not the crappy ones you get at Home Depot. I buy 10 gauge Molex AviKrimp ones from DigiKey. They’re ~33 cents each at Q:250. They are no joke. I use them in the high current path of OpenEVSEs that I build for up to 24A, and they perform perfectly.

Before we dig in, know that the Amazon Smart Plug is designed for use with a 100-120 volt three prong system so it’s a North American product only.

The Model 3 is showing 118V @ 12A which is 1.4kW. The same screen shows 1kW/hour being added, but it is rounding down. I need to take a 8 or 10 hour session and total up the numbers.

Ladies and Gentlemen, I hereby nominate [cyberteque] as the replacement for our recently departed “most interesting man in the world”. Assuming he was, in fact, nearly eaten alive by a feral pig, or trapped under a hang glider under water. Double votes if he was nearly eaten alive by a feral pig who was flying a hang glider upside-down under the water.

During service calls, being able to identify undersized conductors can help resolve compressor start issues or intermittent trips of breakers or fuses. Knowing appropriate and inappropriate breaker and conductor sizes will save you and your customers time and money.

Note: Not all certifying agents offer online lookup, and some have a lag time for posting new certificates. If you are unable to find a certificate online, contact the certification agency or supplier for further verification.

In the second week, I’m not even sure why I did it, I was working on a pinball machine and measured 240V between the chrome plates on the front of the 2 pinball machines to either side of the one I was working on. The electrician had “forgotten” to hook any of the earths for the whole building.

Well yeah, that’s what I’ve seen, they fail on and stay on until either they or the piece of kit they are running catch fire.

Senate Majority Leader Mitch McConnell has been clear that, aside from any spending bills, Republicans’ priority for the end of the year is to keep pushing judges through — and if Flake holds on this issue, it could throw a wrench into that plan.
