Basement Electrical Circuit Wiring Considerations
Considerations to help determine Circuit Requirements:
Important Factor:
Find out if the Main Service or the Panel that will supply the circuits to the basement. Do they have adequate Load Capacity and space for the needed circuit breakers.
How big is your Basement? (Square Feet)
This will be used to help you lay out the basement with general purpose electrical outlets and any special equipment that will be needed.
Special Considerations:
Home Theater - Complete with Surround Sound and HDTV Wiring.
Additional Living Space or Studio Apartment
which may include Kitchen Appliances.

Questions about Wiring a Basement
What would cause some Basement Outlets to Not Work?
Sue, a Handy Woman from Davenport, Iowa asks:
We just moved into a house and we have a finished room in the basement that has about 4-5 outlets. The outlets do not work on one side of the room all the way around. The other side of the room they do work fine. The lights on the wall have to be turned on by the switch on the light and they work. The light switches all work. I have checked the breakers and they are all okay. What could cause the other outlets not to work?
Dave’s Reply: How to Fix Basement Outlets that do Not Work
Sue here are a few items that may help you get your outlets working:
Look for GFCI outlets and check to make sure they are not tripped, and reset as needed.
Turn off the circuit breaker that provides power to this area, then open the last outlet closest to the outlets that do not work and inspect for burnt wiring connections or any burnt portions of the outlet. Replace the outlet if it shows any signs of damage. Burnt or damaged wiring should be repaired by a licensed electrician.

Planning for Basement Electrical Wiring
Question:
I am trying to wire a basement bathroom. Power comes from panel to a light then another light then a switch.
Can I take power from that switch which is the laundry room and bring it over and use it to power a switched light, a separate switched fan and a GFI receptacle. If so, can you please explain and/or diagram.
Thanks
Answer:
Basement electrical circuit wiring should be planned out just as any other room of the home. The lighting may be continued as a branch of an existing light or general purpose circuit as long as there is enough circuit capacity to support the additional added load.
Bathroom GFCI outlets however, must be wired as a dedicated 120 volt, 20 amp circuit or be added to an existing 120 volt, 20 amp bathroom outlet circuit.

Electrical Project Skill Level:
Intermediate to Advanced - Best performed by a Licensed Electrical Contractor.
Electrical Tools Required:
Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time:
Depends on personal level experience, ability to work with tools, install electrical circuit wiring, and the available access to the project area. Electrical Safety:
Identify the panel circuits found in the project area, turn them OFF and Tag them with a Note before working with the electrical wiring.
Electrical Wiring Parts and Materials:
Electrical parts and materials for home wiring projects should be approved for the specific project and compliant with local and national electrical codes.
Electrical Codes and Inspections:
Installing additional home electrical wiring should be done according to local and national electrical codes with a permit and be inspected.
This is a testing tool that 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.
This is great to troubleshoot a problem with outlet circuit wiring, 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.
A wire stripping tool used 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.
