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.

Wire Types and Capacities
Cables and common wire types.

Devices and Junction Boxes
Select the right box for your application.

120/240 Volt Sub-Panel Circuit Requirements

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.
