My office is running from one breaker (14 amp/120v) with 4 outlets and 1 light. I've had a laptop die while plugged into the wall and recently my UPS all audibly cycled on-off within 5 minutes of each other.
The light is using a 78mm Type-J (after moving in I replaced the 100W with a 5W LED)
I assume that three of the outlets were installed as part of the original construction but one of the outlet has mild drywall repair surrounding it, I assume it was added after the fact.
I purchased and tested all outlets with a GFI Receptacle Tester and didn't see any issues.
I've noticed some issues with the room's power:
- Laptop dying shortly after moving in to condo
- 3 separate UPSs activating within 5-10 minutes of each other for a few seconds. The UPSs were not active at the same time (UPSs were purchased after the condo board said I'd have to provide them with a detailed renovation plan before I could have an electrician look at the wiring).
- Prior to installing UPSs, whenever paper was fed into my shredder the LED USB keyboard on one of the computers would visibly turn off for <1 second after the shredder turned off.
There has also been at least one flicker causing the whole unit to lose power since moving in.
- How likely is this related to my office's wiring?
- What are the least destructive mechanisms to diagnose these issues?
- How many hours should I budget for a certified electrician to diagnose and fix the issue?
- If I add an 8A air conditioner to this circuit how likely am I to cause this issue to escalate?
