Skill Level: Beginner to Intermediate – Best if wired by a Licensed Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools and the number of outlets that will be added and the access to the location for the new outlets.
Precaution: Identify the existing outlet circuit, turn it OFF and Tag it with a Note before working with the wiring.
Notice: Installing additional outlet wiring should be done through the local building authority, installed according to applicable local and national electrical codes, with a permit, and have the required inspections.

Wiring Lights and Outlets in a Barn

When adding new electrical wiring onto an existing power source you should first fully understand what the power source is, what it is used for and does it have available capacity to provide power for the items that you want to power.


Areas within a barn may require electrical circuits to have GFCI Ground Fault Circuit Interruption.
