Things Your Electrician Wishes You Knew | 25 Amp Circuit Breaker

I’d love to see a follow piece on how to work with High Voltage as well. Lots of interesting projects to do with microwave and neon transformers…

idk, anytime I’ve been shocked on the job I tend to immediately pull back – usually any screwdriver I have in my hands goes flying, and hopefully its not towards me or anyone else’s face. Which is why I use all 1000v insulated screwdrivers now. Better sorry than safe, kill two stones with one bird. You can definitely “feel” the alternating current.

Buying from people you’ve never heard of, to get stuff cheaper, which is the only reason you’d use Ebay or Amazon, bypasses this whole chain of trust. And, fuck me! it turns out buying stuff from anonymous suppliers, in a market where Chinese scammers are an utter epidemic, sometimes means people don’t get what they expected to.

My son replaced a C-Max with the regular hybrid version of a Niro recently. I would not use “reliable” and C-Max in the same sentence as it needed a new transmission at 77K miles (fortunately covered under a hybrid warranty), had a leaking engine (not covered under warranty), a Sync system that failed twice (covered under a special warranty extension that was about to expire), and numerous other problems mostly electrical in nature. We’ll see about the long-term reliability of the Kia but fuel economy has been in the high 40s (versus 35 for the C-Max) and all-around the Niro just feels like a much nicer car for less money. Personally I will definitely take a look at the plug-in version when I am next looking for a new car and it would be in the color of the one reviewed here so I hope it doesn’t get discontinued as Kia seems to like to do fairly often.

Larger motors used in rural settings and light industry may aswell use 400 voltage between phases by triangle connection. 3 phase 16A sockets are almost never seen in apartments, but are usually found from houses that have garage or other workspace with larger machinery. Larger 3 phase sockets are very common in farm setting and light industrial buildings. E.g. our hackerspace has air compressor that is fed by 3x 400V 25A line. It doesn’t even have neutral line, motor is connected to triangle and 24V for control logic is stepped down from 400V with transformer.

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.

The contacts open because of the electromagnetic force (magnetism) generated in an iron core around which the relay’s coil is wrapped (Figure 3).

This Kia Niro’s cargo area, in contrast, looks very nice! Interesting. Kia’s brand equity isn’t strongly convincing as a sound long-term value-driven purchase. I haven’t driven one, but it sounds like it isn’t great to drive.

Of course in this case, there’s less heat per length of track, but the tracks are longer. So it cancels itself out in the end.

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.

Nissan has said that most people who get their LEAF charging stations installed by AeroVironment will pay around $2,200 to $2,500 in hardware, permits and labor—$750 of which is for the actual charge station hardware. While the pictures are interesting in-and-of-themselves for those of us that care about what happens under the hood of all of our equipment, the bigger question the pictures bring up is what, exactly, you’re paying for when you plunk down your $750 for the hardware.
