Electrical/UPS question

[M A V I C]

I've got one of these:

http://www.apc.com/resource/include/tech...2200R3X167&tab=models

It's rated at 1600W at 120V. That's about 13.3A.

I didn't know it before I got it, but it has a 20A plug (now I know that's what "NEMA 5-20P" means.) Only having a 15A circuit where it was going, I figured I could swap the receptacle and it would be fine as the max power was rated below 15A. Plus the outlet was connected to a GFCI so if there was any big issue that would trip.

Well, the GFCI is tripping.

I have no extra slots in the panel. The wiring is also probably 14 gauge, so not enough to swap the existing breaker for a 20A breaker. The GFCI is about 15 years old. Is it worth putting a new one in just in case that's the problem, or do the stats on that thing pretty much require a 20A service?

Thanks much.

You could get one of these type breakers: http://www.hardwareandtools.com/invt/6943021

Combine two 15 amp circuits then run a new 20 amp on the free slot.

My breakers are pretty much those already. I was at home depot and I see they have dual 20A for $8. And wouldn't I still have to worry about the wiring?

Yeah, you don't want to run 20 amp over 14g. You seemed to imply that if you could get more spaces that you were able to run a new circuit.

tsk tsk tsk, always consider your power needs before building a data center!

I think code requires 12 gauge wire feeding a 20 amp outlet, but I could be wrong, and codes are different in different areas.

WARNING !!
A "full Panel" is often a sign that you're pushing to the 'ampacity' capacity of your house. The problem here is that circuit breaker panels, main power feeds, and so forth are all sized based on a lower level of power utilization , based on, say, a 1970's household. Look around and see the number of electrical appliances that you've got running, and THEN decide whether or not you can use one of those dual breakers.

Fortunately with CFl lightbulbs and such, power usage is dropping, so you are probably going to be okay. Just because your outlets aren't full of 'CHristmas Vacation" style daisy chained extension cords doesn't mean the same basic effect is taking place within your main circuit panel.

MAVIC'S house is roughly 2000 vintage I believe.

1993.

Things like the garbage disposal, microwave... are on 20A breakers but only have 15A outlets. Plus my house is wired for an electric dryer but we have a gas one. So I don't think going from one breaker that's 15A to one that's 20A is going to be a problem as far as overall load goes.

Hey, do you have a 100, 125 or 200 amp service?
