I don’t use my infrared camera as a quantitative tool; I use it as a qualitative tool. Yeah, I know, more blowhard words. Put simply, I’m not too concerned with the exact temperatures that are displayed on my infrared camera. As a home inspector, what I’m concerned with and what I dig into are the meanings behind unexpected temperature differences, aka anomalies.

We recently had a chat among the Hackaday writers about how we could approach this subject. The easy way out is to be all Elf-and-Safety and join the radioactive anthrax crowd. But the conclusion we came to was that this site is a resource for hackers and makers. Some of you are going to lift the lid on boxes containing significant voltages no matter what, so we thought we’d help you do it safely rather than just listen for the distant screams.

Using SO for internal wiring is something that I have often done — it is resilent, flexible, and high temperature. Also a joy to strip.

The device uses two hot and one ground to supply the 240V output which is, in some business where there is three phase power this will be closer to 208V but should still work. Obviously you shouldn’t be doing this unless you know exactly how it works, and we applaud [Nick] for airing these hazards while at the same time supplying the knowledge behind the concerns.

If you’re commenting on my mention of clothes-dryers and stoves that was merely editorial. Plus, my house has one on the stove but I don’t particularly want to pull the stove out and unplug it so you can charge your car.

The main benefits of the RGC..32 include the fact it has the highest amperage rating of any 17.8 or 22.5mm wide solid state switching devices available on the market, DIN rail spacing over 22.5 mm platform, optional cage clamp power terminal for wires up to 3 AWG size, and energy savings due to lower power dissipation.

Didn’t have to purchase any EVSE. My 2016 Volt came with one, that was L2 capable. You only needed to make a pigtail. It’s actually a Clipper Creek. So, for about $60, I installed a NEMA L6-20 outlet, with 20amp double-pole breaker, and 8 ft of 10-4 wire that I had left over. $20 got me a permit.

I think Brian’s point was that if the bond between the earth ground and the neutral return of the incoming premises power isn’t good enough, then the short to earth might *not* trip the breaker. Of course, it would likely start a fire instead (the resistance may not be zero, but it will be low enough to sink a great deal of power in most cases and a 15A breaker will tolerate a couple THOUSAND watts), but I think that if you can’t trust that the building is to code, then all bets are off.

Video capture is an area where the Sony A33′s translucent mirror technology makes a huge difference relative to pretty any other SLR currently on the market, and relative to even fast-focusing SLDs. Every other interchangeable-lens camera currently on the market either doesn’t autofocus at all when recording videos, or has to resort to slower and/or more obtrusive contrast-detect focusing. Because the Sony A33′s phase-detect AF system is always looking at the subject, fast autofocus during video recording is no problem.

We, uh, we don’t have sauna heaters down here. We have air conditioners In semi-related news, it was forecast to be 40C today…

You could make a multimeter that had an internal switch for volts / amps. But I think electricians wouldn’t trust it. So it’d be a useless feature, as well as, probably, increasing the shunt’s resistance. And be another point of failure somewhere dangerous. Etc! Nobody wants a multimeter that killed their mate.
