Why Electrical Outlets Do Not Have Full Power
Why do my Outlets not have Full Electrical Power? How to Troubleshoot Electrical Power Problems.
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, who is a Handyman in 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.

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 an Electric Power Problem
Application: Electrical Troubleshooting a Outlet Circuit Power Problem.
Skill Level: Advanced – This electrical testing process is best performed by a Certified Electrician or a Licensed Electrical Contractor, or the electrical utility company.
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 Electric 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 voltage back through one leg of a 220volt circuit that is turned on.
- The Cause of Lost Power or Dim Lights
The electrical panel may have a faulty connection either with one of the main power lines, or a problem with the neutral, however this is typically a fault with one of the main power lines.
- Possible Fault with the Electric Panel Main Breaker
It may be that the main breaker for the panel is partially tripped, or the breaker may be faulty.
- Possible Problem with the Main Electrical Utility Wires
Another possibility is that one of the main power lines from the electrical utility provider may be faulty. If this is the case, then the electrical utility company should be notified about the problem. If the problem is with their side of the electrical service they would need to inspect their electrical wires and make any necessary repairs.
- Inspecting the Electrical 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.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
