Why Electrical Outlets Do Not Have Full Power

Electrical Problems That Cause Abnormal Power
Electrical Question: Why do my outlets not have full power?
Electrical Problem #1: My outlets are not making full electrical power.
- I had my kitchen microwave plugged in and a few days ago it just would sort of bog down when I turned it on. I thought it was broken so I bought a new one. Well, the new microwave is doing the same thing. So I thought I would plug it into other outlets, but the same thing is happening. When the refrigerator turns on the lights in the house fluctuate. Also worth noting, a few days ago there was a funny “shorted out” smell coming from the room with the breaker box. I removed the breaker box cover and all the wires are exposed and I don’t see anything that looks burned or out of sort. Any advice?
Background: Sam, a Handyman from Midland, Texas.
Example #2: My power equipment only runs at 1/4 speed or less and if I turn the lights off I lose all the power.
- My shed has 2 circuits, one for lights and one for receptacles. The circuits are 15 and 20 amps.
- I recently have lost power unless both circuits are on.
- When I do have power I am unable to operate any power equipment because they run at 1/4 speed or less.
- If I turn lights off I have no power to the receptacles.
- I have 110 volts to the circuit breakers and the same to the receptacles only when lights are on.
- This a small workshop. I began having problems when my air compressor had problems which I have discarded.
Any help much needed! Thanks.
This electrical wiring question came from Paul, in St.Michaels, Maryland.
Example #3: Some of my outlets lost full power, there is only a little power.
- I have 4 outlets that lost power all of a sudden, no fuses blew.
- The outlets have a little power but not enough to run anything.
- I rewired one outlet with new wire and outlet, its the only one running to 1 fuse right now and it still has only a little power.
- I disconnected other outlets that aren’t working from fuse box still not working, rest of the house is fine

Thanks for your electrical wiring questions Sam, Paul and Carl.
How to Troubleshoot Electrical Power Problems
Application: Electrical Troubleshooting a Outlet Circuit Power Problem.
Skill Level: Advanced – Best performed by a Licensed Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools, Voltage Tester or Volt Ohm Meter.
Estimated Time: Depends on the type and age of the electrical wiring and the access to the circuits and wiring to be evaluated.
Precaution: This is a project that should be performed by a Licensed Electrical Contractor and typically requires specific tests of the electrical circuits.
Notice: Repairs to Home Electrical Wiring should be done according to local and national electrical codes and installing new or replacement electrical parts or equipment may require a permit and inspections.
Common Causes of Partial Power
The electrical questions above describe the symptoms of a problem within the circuit wiring. Listed below are the most common causes of lost power or partial power.
Examples of the Typical Causes of Lost Electrical Power
- Voltage Feedback Causes Partial Power
The electrical system most likely lost one leg of power so the circuits are feeding back.
- Inspecting the Circuit
The lost portion of electrical power will need to be identified by inspecting various circuits and components of the home electrical system.
- Repairing Burnt Wires
When burnt wiring connections have been located at either a terminal connection or within an electrical splice the repairs will need to be made according to code and using the appropriate parts, including a replacement receptacle outlet, new wire, and wire connectors.
