Troubleshooting No Power to an Electric Outlet Circuit
Electrical Question: I have a single family home with two floors. Everything electrical works on the first floor but on the second floor, only one side of the house is working for electricity.

Thanks

This electrical repair question came from: David, a Homeowner from Lawrence, Massachusetts.

Additional Comments: It’s a great website and I hope to learn from it.

Dave’s Reply:
Thanks for your electrical repair question David.

Preparations
Application: Troubleshooting and Repairing Outlet Problems.
Skill Level: Intermediate to Advanced – Best performed by a Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools, Voltage Tester or Volt Ohm Meter or plug-in circuit analyzer.
Estimated Time: Depends on the age of the home and the condition of the electrical wiring and access to the circuit wiring to be inspected, evaluated and repaired.
Precaution: Identify the outlet circuit at the electric panel, turn it OFF and then Tag it with a Note before performing any wiring inspections or electrical repairs. If an outlet or the electrical wiring is found to be damaged then repairs and replacement parts should be obtained with the same voltage and amperage rating.
Notice: Burnt or damaged electrical wiring and circuit components should be replaced with new electrical materials of the same voltage and amperage rating.

How To Locate and Repair the Cause of Circuit Power Loss

Procedure to Find the Cause of  Lost Power to a Circuit

  1. The circuit outlets and receptacles will need to be identified.
  2. The circuit should then be shut off.
  3. Each outlet should be removed and inspected for a burnt connection or a burnt splice.
  4. Begin by inspecting the outlet that the vacuum cleaner was plugged into, because vacuum cleaners require a high amount of electricity that may create stress on the outlet circuit wiring and components.
  5. The damaged wire will need to be repaired.
  6. New wire connectors installed as needed.
  7. New receptacle outlet installed as needed.

Electrical Tips to Help You Wire it Right

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.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

    Could you provide some info on split buss load centers. They stopped making them in 1968 but there are still plenty installed and they are in code as to the six handle rule. I have seen electricians tell homeowners that the panel is defective and needs to be replaced but not explaining how the panel works. I was able to provide a customer with a diagram of his panel, far more than two electricians were willing to do. The original problem for the homeowner was a defective breaker which costs twenty five dollars instead of several thousand that he was quoted.

    • Dave Rongey says:

      Hi Roger,
      I haven’t seen a split buss panel in a while, however they are still quite a few around as you have mentioned. I believe the original design was to have two sections, one section for the smaller circuits and one section for larger 240 volt equipment such as air conditioning and heating equipment. The design idea may go back to how some of the old fuse panels had two separate cartridge fuse disconnects supplying power to the same types of loads, however the amperage was much smaller with the earlier electrical systems. As long as replacement parts are available and the panel is in good shape there is no need to upgrade if the panel is still within the load specifications.
      I hope this helps,
      Dave
