I will start with giving my level of understanding:
- good foundational knowledge of DC auto electrical troubleshooting.
- understand Ohm's law.
- understand safety precautions and procedures.
- have limited experience with AC current/circuits.
Here are the symptoms:
- A 20A breaker blew a few times and then failed. I replaced the breaker.
- One pair of receptacles on this circuit no longer works. Everything else powered by this circuit works fine.
- These receptacles are located on opposite sides of an interior wall and are supplied from the same junction box.
- The receptacle on one side of the wall is rarely used.
- The other receptacle powers only a desktop computer, monitor, inkjet printer, and two lamps with 60 watt bulbs.
- This configuration has been trouble free for years.
- All outlets show 110v with a circuit tester, but fail to power a known good drop light with a 100w bulb.
Here is what I have checked:
- visual inspection of wiring and connections for both receptacles
- visual inspection of all wiring for this circuit in the attic
- visual inspection of all wiring and connections in the junction bos for this circuit
- visual inspection of all wiring and connections in the breaker box.
I found no loose connections, evidence of heat, or evidence of corrosion. Logic tells me that I am getting voltage, but not amperage to carry a load. What else can I check before calling a professional?
Thanks for your helpful advice.
