There are only two conductors run from the substation to a normal one phase installation. Those are live and neutral. Though the neutral is bonded to ground at the substation through the resistor and is also connected to earth at any and all points on the cable where any work is done it is still neutral. At the house the neutral and ground become separate conductors. The neutral is treated as a live wire when working on the system, as far as I know all utilities treat neutral as another phase for safety reasons.

It’s good to see a snubber on the design (that’s often omitted on DIY designs I’ve seen). There are a few TRIACs that are designed to commute highly-inductive loads (“snubberless” is the marketing term I’ve seen) — may worth looking into them to reduce the BOM.

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.

If you run a separate earth wire that is hard grounded at the sub and hard grounded at your house and nowhere in between. In this situation if you get a lightning strike at or near your house then the ground potential rises. This flows through the earth wire to the sub ground and can be a massive current, enough to make the network fail dramatically. This rise in ground potential can also be caused by other things such as a faulty insulator on an MV or HV tower (pylon) or pole. Even if insulators are good then you can still get this ground potential rise. You can easily measure it with a length of wire and two earth spikes, put one near a tower and the other a distance away and you can see a significant voltage. If you also have a separate wire called neutral running form the sub then the potential between that wire and the earth wire is unknown so you have a risk of lethal voltage between neutral and earth, a situation that is not expected and potentially extremely dangerous.

In some cases, contractors have stated that certain municipalities are requiring that conductors be sized based on the breaker size instead of the MCA. This is not uncommon, but it is usually a matter of a respectful conversation about the above NEC articles. The “authority having jurisdiction” or AHJ is responsible for interpreting the code, and they can make any standard they see fit. While certain local legislation may supersede the NEC with additional regulations, the NEC is a nationally recognized standard throughout the U.S. It is rare that a building department will ignore entire articles of the NEC when it is brought to their attention in a respectful manner.

Agreed. I work in electronics as a profession. High voltage electronics no less. Industrial size high voltage power supplies. Everything about them up to maintaining them down to component level. The comments here from people are scaring me shitless from the lack of knowledge to the over the top over complication of the problem.

Online reviews are useful when you’re on the hunt for a trustworthy electrician. If the person with the lowest quote also has the worst ratings, it’s worth shelling out a bit more. If that cheaper electrician messes up, you’ll just need to call me (and my higher price) and pay more overall.

Anyone know a good source of information for dummies on electromagnet math? I’d love to build one of those electro magnetic pan brakes, but blindly connecting 240VAC to a coil scares me.

These rules of thumb are referring to the amperage capacity or “ampacity” of the conductor (wire) and are often correct. Sometimes, these general rules lead technicians to believe that if an appliance is rated for 50-amp breaker/fuse maximum overcurrent circuit protector (MOCP), you must use 6-gauge wire and a 50-amp circuit breaker.

Once you have the outlet, a level two fast charger is as little as $150 for 16 Amp, which gives 3.5 kilowatts, or $300 for 30 Amps, 7 kilowatts.

In the waning days of Flake’s presence in the Senate, the Arizona lawmaker, who’s frequently clashed with Trump, now has dwindling opportunities to make his mark. Longtime observers of his tortured reluctance to back Republicans going in a direction he does not like will recall that such stands often end with Flake simply, well, flaking.
