Hooked up to 220

I found it, cut it off and left them with out the piece of equipment for a couple of days as a lesson. Plug went into my training box of things not to do.

Every time you make something idiot proof a different idiot comes along and defeats it.

Ordinarily, a 20 amp socket has both the sideways and the "normal"... If they had a 20 amp drill attempting to use it on a 15 amp circuit, i get it... I would have done the same thing instead of standing around waiting for something to happen.

I have wired houses, installed sub panels, AC, HVAC, generator transfer switches, etc. But still for the life of me cannot grasp the concept of three phase! LOL

LOL... Simple if you are trained in it.

I've wired it, used to work in a factory as maintenance, but the concept of how it works eludes me. Then again, that was 35 years ago! LOL I haven't touched 3 Phase since.

Thanks for the vote of confidence Frank. Wasn't it you who straitened be out on this a few months ago?

All my house sockets measure about 120V. Haven't seen 110V in years, unless the circuit was overloaded. Strange how everyone still calls it 110V...

I was curious so did a bit of digging; 110 volt was the original set up by Edison, it delivered 100 volts nominal, by the 1930's it had increased to 115 volts, but was not codified until 1968. Around 1984 ANSI/NEC set the standard for residential to 120 volts +/- 5%. And that is where we are today.

We are just old. And not necessarily any wiser either :-)

Right and same with 220, it is actually 240v. So if you say 120/220, then it is incorrect, if you say 110/220, it matches but is still incorrect, so in actuality it is 120/240v. To get 240 it doubles the poles, and is fed off two separate busses from the main panel.



Going way way back to when I studied electronics for a career that thankfully never happened, TV and VCR repair, I recall something about how 120v came about from the frequency of the generation, 60hz. Since AC runs positive to negative to the neutral, doubling it gave 120. But then again that was like nearly 40 years ago, and I have not studied any of that since.

have you hit the ceiling on wise? it's good to be old but better to be older!

Strictly speaking, the voltages we have been talking about have belonged to the US and mostly North America. The rest of the world relies on 50Hz rather than 60 and the voltages are greater per outlet than the US. here's a map to 'splain

https://en.wikipedia.org/wiki/Electr...,_Detailed.svg

being in the electrical bizness, makes me learn this sort of stuff and being an RCDD incorporates low voltages internationally.

Well if I ever turn my RV into a Caravan, I will make sure to up it to 230v for the European standards! Japan is 50hz and 100 volts in some areas, so guess I wont be taking it there anytime soon.

120 volts is the maximum standard. 110 volts is the minimum standard. 115 is the nominal voltage.
My household voltage is usually 118 to 120 volts.


oops, someone else already answered this.

Need to move

Ours sits around 124 volts and we are at the end of the line. I seldom see anything below 120 volts even during peak season with all the A/Cs running.

We are on a EMC (co-op) and have outstanding service, even when a string of tornadoes wiped out several transformer yards we had power back within less than 48 hours.

Want a head scratcher? Try southern hemisphere 240, two wire electricity. One leg, load and return and the color code can be blue and brown or black and red. Sometimes a ground or earth and in the older load centers or switchboards replaceable wire fuses. Circuits breakers are being used now but the busses are different.
Wire sizes are set in actual wire size and not AWG sizes.

I have slept since I made that remark.



Interesting enough, the older I got the wiser my Father was.......hmmm
