Electrical Outlets with Power Problems
How to Repair Electrical Outlets – Locating a Loose or Burnt Wire or Splice Connection – A burnt or loose connection is typically found in an outlet junction box or receptacle box where two or more cables and wires are spliced, or where the wires of the circuit are attached to an outlet.
Causes of Power Problems with Outlets
Electrical Question: I have the old style fuse box which takes the screw in fuses. The problem I am having is I noticed certain plugs in the house are getting more power than others. For Instance when I plug a fan into one outlet it doesn’t turn as strong as another outlet. Our microwave oven does not have the same strength in one outlet but it operates OK, yet another outlet it cooks food fine.I have changed the cartridge style fuses and still have the problem.
Can you give any advice?
Everything has always worked fine, don’t know what happened.

How to Repair Electrical Outlets
Robbie, what you are describing is an indication that one of the wires within the outlet circuit has lost a connection.
Skill Level: Intermediate to Advanced.
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with hand tools and electrical troubleshooting skills.
Precaution: Identify the outlet circuit, turn it OFF and then Tag it with a Note before performing any wiring or inspections. Electrical troubleshooting is best performed by a qualified electrical contractor.
Locating a Loose or Burnt Wire or Splice Connection
A burnt or loose connection is typically found in an outlet junction box or receptacle box where two or more cables and wires are spliced, or where the wires of the circuit are attached to an outlet. Loose connections may develop which can lead to a burnt connection or splice which can cause the connection to be lost.
Causes of Low Voltage or Partial Power
- Partial power or abnormal low voltage is primarily due to a feedback of electricity within the circuit which can flow through an electrical device that is plugged into or connected to the affected circuit.
- For example, if an electric cooker is plugged in, then electrical power can pass through the heating elements of the cooker which acts as a resistor that will produce a lower level of electricity at another outlet location that is on the same circuit where there is a lost connection of one of the main wires of the circuit.
- This is especially true when one leg of 220 volt power has been lost and power feeds back through an 220 volt electric range or 220 volt electric dryer.
Wiring Electrical Outlets for the Home
- Home electrical wiring includes 110 volt outlets and 220 volt outlets and receptacles which are common place in every home.
