The 2, 2.5 and 3 ton in that model line has a min amp device of 20. the 3.5 has a min amp of 25. The 4 ton is min 30, and the 5 ton is min 40.

Any location outside, even in raceway, requires the use of conductors rated for wet locations. Using THHN would be a violation if installed outside.

THHN is dual rated THHN/THWN.

Using THHN outside is a violation. It's rated for dry and damp locations only, as I'm sure you know. The comment I responded to had no reference to multi-rated wire, such as MTW/THWN-2/THHN, which is acceptable to use outdoors.

Not if it doesn't say THWN.

And how often do you see straight THHN? Almost never.

Oooops I forgot this is a forum and I should have been VERY clear we dont buy THHN that is not dual rated as a matter of fact I am not sure if it is available without a special order. Next time I will be sure and post DUAL rated THHN must be in conduit.

Not true. Not all outdoor raceways are wet locations.

All underground outdoor raceways are though.

I'll ask the same thing. When was the alst time you bought new THHN that was not dual rated with THWN??

It is so petty when folks just HAVE to point this out when it is a complete non-issue.

10/2 air conditioner wiring - clarification


I've only been on this forum for a few weeks. I came to get reasonable answers/ideas from reasonable people. However, this forum seems more of a school yard mentality (my dad's better than your dad).

Anyone know a forum where I don't have to filter though all this bs?

Might I suggest you get a thicker skin or possibly be less picky?
I don't know what thread you are reading but in this one all I see is adult discussions about technical issues.
Can you point out the "my dad's better than your dad" stuff you are talking about?

what question do you have that was not answered ??


but .. here ..


120 v is 1 hot to 1 neutral ....

240 is 2 hots .. no nuetral needed in its purest form ... ( so 10/2) would be fine ..

some things need the neutral wire to run the lower voltage (120v ) stuff so 10/3 is used ie your dryer and your stove, the cotrols, timers, clocks, etc are 120 v

Well, we'll just have to agree to disagree. I'm sure somewhere in the US, there are still spools of THHN that is not labeled as THWN. I agree that this is a non-issue for professionals for two reasons:

1) We mostly only use newly purchased materials and probably don't have a spool of wire that is more than a few years old.

2) We know better.

My post was directed at the DIY, who is more likely to try to re-use materials. How many times on this forum have we heard things like "Is there a way I can use this wire, it's what I already have?" I just wanted to be clear that people need to read the markings on their wires to know that can be used for.

If the raceway is exposed to weather, it's a wet location. I can't think of a raceway I've ever run outside that wasn't exposed to weather for at least some portion of the run.
