APC UPS XS-1500 Tripping a 20 amp breaker - What is the working load?

This was originally posted on APC forums on 1/3/2010


I have been using a UPS XS-1500 to protect an Apple Mac Pro Quad Core Desktop, that is acting as a workstation and data server for a home network. One year ago, the 20 amp dedicated circuit breaker for this system started to trip. I replaced the breaker. A year later after flawless operation, the replacement breaker is beginning to trip randomly at times when I am away from the Mac. Wiring is only 5 years old on the home. The only additional loads to the Mac Pro which draws 12 amps max on 120 volt service, comes from:
- Two Samsung 24" LCD monitors using about 55 to 80 watts each.
- Logitec remote Mouse
- Bose Companion 3 speaker system.
My question is this: With the above configuration, how much extra curent draw in amps does the XS-1500 draw? Does the XS-1500 have the capacity to absorb and protect the household (input) power source from any current draw down spikes that may occur from the equipment plugged into the APC? If not, does the XS -1500 add to the current draw down spike that occurs the the Mac Pro comes out of hibernation to survice a network or workstation need?
I could not get any input breaker capacity information on this unit. The newer APC UPS 1500VA LCD shows a max current input of 12A and a Input Breaker Capacity of 15A.
If this unit is similar to the UPS XS -1500 I am using, Would it make sense to assume that the 15A breaker limit covers what ever can be plugged into the APC. or do I need to add the Max Input Current load of the APC, 12A to the load of what is being plugged into the APC i.e. My Mac Pro and the other goodies?
Your thoughts and wisdom would be greatly appreciated on this series of questions.
Many Thanks,
Michael

Erasmus,
Thank you for your thoughts on this. Very helpful! I am going to have the connection lugs in the breaker panel and outlet checked to make sure they are tight.
Best regards in the New Year,
Michael
