230v 15 amp on 14/2

[Motown 454]

Hi I have an A/C unit in my bed room it is 110/15 amp. Can I run a 230v/15 amp on the 14/2 that's already there if I change to a double pole breaker ? The receptacle is about 40 feet from the breaker.
Thanks.

As long as you don't need a neutral, and the outlet is on a dedicated circuit.

It says it a three prong plug counting the ground for a regular receptacle. It is a dedicated circuit.

If the unit itself calls for 15A, and you don't run a 20A two pole breaker, and

12-2 w/grd romex to it, I feel you will be making lots of trips to the panel to

reset the new 2 pole 15A breaker. But you will discover that soon enough.

It is possible that the unit calls for a 15 amp circuit, and doesn't draw 15 amps. However since that is not clear in this thread it is impossible to really advise on whether to go 20 or 15 amp circuits.

Without sufficient information advice is useless!

Also he's saying currently there is an A/C unit on the circuit, not that he's going to put one there. We don't even know what he plans to use that circuit for--maybe a welder? Or a small milling machine? Me, I've always wanted a small milling machine in my bedroom in case I get the urge to mill something in the middle of the night .

^^^^ THIS!

I generally prefer to size the wiring on things like that at 125% of name plate rating,so if it pulls 10amps for example youre looking at 12.5A which is still under the rating of that wire and breaker.
If you do use the existing 14/2 make sure to wrap the the white neutral wire with black tape at both ends so theres doubt about whats there in the future if somebody has to work on it,if somebody were to install a 120v plug on that 240v circuit it could smoke a whole lot of expensive stuff.

Thanks I'll try to see how many amps it actually uses.

It has rated cooling amps AHAM 5.8/6.3 then cooling watts 1235/1215.
Does this give you enough information? Again thanks for the help.

Different question. Are you allowed to use a white insulated conductor as a "hot" conductor ?

 

[zmaxmotorsports]

That's why you wrap the white wire with black tape on both ends to identify it as carrying current.

 

[Motown 454]

I thought you could.

Multiply the 5.8amps x 125% and your only pulling just over 7amps at worst case scenario,Your 14g wire is plenty.

Thank you all for your help.

Am I missing something here? Why do you want to run 220/240 to an air conditioner that requires 110?

The 110 v A/C in my bedroom crapped out. I can get two, 220 v A/C's for sale at almost 2/3 the regular price to fit in the same sleeve in the wall. So it would save me $400 if I can use the one for my room. The other is for the garage. The walls are open in there so I can run any wire I need to.
