I need to do some electrical work on a circuit in my home. One of the outlets on the circuit has a UPS battery backup plugged into it. The UPS is tucked away behind a lot of other equipment, so I'd rather not have to unplug it if its not necessary. Is there a risk of the UPS "leaking" (or whatever the term would be) back onto the circuit when the breaker is tripped? That is, for safety, should the UPS be unplugged before I work on the circuit?
Specifics in case they matter:
- I am replacing some switches for lights on the same circuit as the UPS
- the switches do not control the outlet the UPS is plugged into
- the UPS is a bXterra BM1500AVRLCD (1500VA)
