What Most Techs Get Wrong About Wire Sizing | 2017-09-18 | 25 Amp Circuit Breaker

Experts suggest buying an EVSE that can produce at least 30 amps of power. Generally speaking this type of unit would be able to add around 30 miles of operating range to a given battery pack per hour. Some EVs can get along with fewer amps, but buying more capability than you may need today makes the installation “future proof” should you eventually trade in the vehicle for a model that can handle the added capacity. However, if you’re planning on using a 30-amp unit you may need to upgrade the line’s circuit breaker to one that’s rated for at least 40 amps.

I disagree, I think L1 EVSE represent a real safety concern. People use corroded outdoor outlets, poorly wired outlets, extension cords (without proper checking for damage or heat build up), etc.

Pioneer has announced it is offering three in-dash receiver models for your car that support CarPlay and Android Auto. Pioneer says that the units — the AVIC-W8400NEX, -W6400NEX, and -W4400NEX — are the first in-dash receivers to support FLAC files without the need to convert, and they’re the first that can connect wirelessly or over USB to both Android Auto and Apple CarPlay, as reported by Engadget.

The thing about the picture that worries me is the receptacles seem to be mounted below 18 inches from the floor. That is a BIG NO-NO. IF there are any gasoline cans in the garage for an old lawn-mower, etc then he has just created an explosion hazard.

At least you thought about fuse and earth ground wire. Hopefully you also kept the thermal fuse of the iron – normally they have one to prevent fire in case of a welded thermostat contact (or short circuit in the solid state relay). And hopefully you kept or built a good case for all this (the open part of the iron).

The spark-gap Tesla coil itself was

For this application I would have used a contactor from a reputable supplier that breaks the connection on both legs of the 220V circuit vs a cheap ebay SSR.https://en.wikipedia.org/wiki/Contactor

I play around w/ HV/low amperage PSUs all the time, that stuff will make you lose control of your muscles…

After a long, bitter, loud argument with the plant “electrician” I finally got him to check the distribution board, when we opened up the “big grey box” first thing I saw was all the earths, bundled together with tape and just hanging there. From where I was standing I saw a fuel tanker driver hooking the earth lead to his truck, which came into the same box.

I have never seem a ‘cooked’ TRIAC or a TRIAC that is not working properly unless it has exploded.

People that build or use 3D printers aren’t necessarily qualified electricians or know how to handle high voltage safely. That’s what I mean for ” Can’t let Darwin wipe them out when they happens to the target market… ”

You can also see the top of the mechanism for the tilt / swivel LCD panel, peeking out on either side of the electronic viewfinder. The viewfinder itself projects quite a bit from the rear of the camera, a decision that was apparently necessitated by the tight packaging of components in front, including the AF module, popup flash, hot shoe, and microphones.
