Does Tesla Make The Best Value EVSE For Non-Tesla Owners? | 220v Contactor Relay

In the US, sharing neutrals between circuits is generally prohibited in the National Electrical Code, 200.4, which says, essentially, “Don’t share neutrals, unless we say somewhere else in the code that you can.” That bit was added in 2011, though other parts of the code cast a penumbra that seemed to say that sharing neutrals was verboten before 2011. In 2011, it became clearly prohibited.

Yes, I get that there are societal differences between Eastern ideals and Western ideals. Please understand that Americans also build cheap crap, too- but being across an ocean makes buying and selling a little different, especially with a language barrier and different societal norms. I’ve been bitten by a couple of misrepresented products before on AliExpress, (RGB mechanical switches that were actually just RGB LED’s), but that was my fault- I didn’t look very carefully, and didn’t do my due diligence.

But yes, 1A is the absolute maximum, peak value for the MOC3041M for a brief amount of time. Even the MOC3041’s 8A maximum, temporary rating is unsuitable as a peak for a typical 15A US mains.

Yeah really though. It’s kind of embarrassing. I’m an engineer and work in big industry (usually minerals, bulk material handling, oil and gas, doing a big robotics project right now for a wood products plant, etc.) and this would be an afterthought. No one would even question it. I mean really a no brainer. People use electric blankets on their bed. I really don’t get it. It really shows how amateur hour most of the people who comment on this site are.

Generally, most LED power supplies are a constant-current type, and are often referred to as LED drivers. These can be purchased as off-the-shelf assemblies containing MOVs to meet lower-level surge requirements.

We recently watched [MakeItExtreme] turn a couple of microwave oven transformers into a somewhat ill-advised wall-climbing rig. It looks like that may have been the inspiration for this build, and the finished product appears to be a tad more useful this time. The frames of three MOTs are cut open to remove the secondary coils and leave the cores exposed as poles for the future magnets. A shallow dish is fabricated out of steel and the magnets are welded in place.

Overall, there’s little question that the Sony A33 has the best video AF of any interchangeable-lens camera currently on the market, but if you plan on doing much video recording, I’d suggest you also plan on buying an accessory external microphone to record the audio.

It’s *mostly* read-only. They usually have a LED for power-on indication. You could stick something to the front to detect that, if you needed a response. Tho for things like lights, usually the user will press the button again if they don’t come on the first time.

1. A hot-neutral reversal will supply the 208/240V relay with 120V. It will make an angry buzzing noise but won’t close. Two hot-neutral reversals will supply it with 0 volts.

When finished “fixing” things, you want to make sure, your device is still safe to the user. For this you need these testers.

Considering the existence of deep subzero freezers, it would still perform better than a resistive element. Or have it draw the heat from the indoors and run some crypto miners to make up for it.
