There's no such thing as a 2013 NEC.
The next edition after the 2011 is 2014.
Also there's no such thing as 220 in the US. It's been 240 since the 1930s.
Sharing a Neutral between 4 circuits with mixed voltage.

Well, I guess I successfully communicated what I intended. Tis true that in US it's nominal 120 volts and 240 volts today, even if appliances are labeled 220. And the stores that advertise both 220 and 240 appliances - neat trick.
I find in googling the issue, you've made correcting people on it a personal speciality. Well done.

We can always count on a useful voltage nomenclature correction here. Thankfully it really changes things for people to know 220v is 90 years old. Think of what they could have done based on tbe wrong info

which appliances are labeled 220v? I have yet to see one.... which stores advertise 220?

I'm a retired EC with 45+years in the trade.
The focus on this (and every other) board is the correct info.

I might be being a little pedantic here, but derating to #10 could begin at 7 conductors if the ambient temps are over 96 degrees F, or as few as 4 conductors if ambient temps are over 114 degrees F. (310.15(B)(1)) Granted, this is probably not an issue if the conduits are just running through the garage, but it's definitely something to keep in mind if they run through an attic space.

Well then soldier on.
Good to know we are still passionate about this... Good to know I won't be able to run this equipment that was designed and built right here in the United States

I was speaking about the incoming power supply, not individual appliances.
Do you know of any 220 supplies in the US?
How do you know this particular piece of equipment was made in the US? Is it marked someplace?

It's built in Assumption Illinois.
If I corrected every person I talked to that said "220" I would be doing it all the time. But I know what they are talking about and it's not productive to tell them they are wrong.

Just looking it up and didn't become 240 until 1967. I was a teenager by then and certainly knew everything worth knowing.
Confounding it changed from 110 (Edison's choice) to 112 to 115 (REA act 1936) to 117 and finally to 120 - starting in 1920s (?) and finishing in 1967. What's next?

Not sure what the next step will be, but I am sure that if there is a change, we'll be paying for the privilege. And our grandkids can spend all day telling people on forums that it hasn't been 120v in ages

The source for my claim is a thread at Mike Holt's website.

I take exception to the info in the thread you quoted on Mike Holt. His Michael Keaton quote is attributed to “The Money Pit”. The movie was”Mr. Mom.”

You guys ever realize how irritating the pedantic bickering about voltage is to the average person?
I get it, but at the same time it's like correcting someone for saying Kleenex when they actually mean facial tissue. 90% of the time we all understand the coloquialism.

Here's one: https://electronics360.globalspec.c...gradually increased over the,at 60 Hz in 1967.
where it says:
"Voltages gradually increased over the years from 110V to 112V, 115V, 117V and finally to the current standard of 120/240V at 60 Hz in 1967."
but in googling the question I found basically the same info in many places.
It may be the Distribution Voltage vs Utilization Voltage. Don't know.
Loved further down in Holt thread they state REA installed "A 60 amp, 230 volt fuse panel" as the standard. Also, in the post you cite: "People however are not swift on the change though, so LOTS of people still refer to residential as being 110/220, or 115/230 or 120/240 (inset joke from the movie "The Money Pit" where Michel Keaton says "220/221.whatever it takes..."). But OFFICIALLY, it is supposed to be 120/240V."
Appreciate you wanting to correct the record. (Like the way I feel about movies and such that suggest one fire sprinkler opening causes all of them in the building to open - grrr.) I'll try to get it right next time.

This same nonsense, perpetrated by the same 3 people over and over, ruins every single thread about someone asking to install a 240v circuit.
There's historical precedent for that nomenclature, and evidence/proof of it has been posted multiple times. It causes no confusion at all. We all know exactly what someone is talking about when they say "110/220". Saying "tHerE's nO SuCH tHiNg aS 220 iN tHe uS" is not helpful and may actually cause even more confusion. You're just being a pedant and you KNOW the entire thread is going derail the moment you post that sentence. So just freaking stop because it's beyond irritating seeing every single newbie's thread being completely driven off the rails, every single week.
If you just really, truly have no self control and HAVE to correct someone, use something like this, which is far less inflammatory and far less likely to derail the thread: "P.S: I know 110/220 is commonly used to describe voltages in the U.S., but it is now actually 120/240. Just an FYI to hopefully avoid any confusion."
I'm just going to start reporting posts where someone says "tHerE's nO SuCH tHiNg aS 220 iN tHe uS". It's purposely inflammatory and unhelpful. At this point, it's clear the same 2 or 3 people are doing it over and over to create arguments and get people riled up.
