How to add Another Electric Outlet
Application: Adding a 120 Volt Receptacle Outlet.
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.
Check to Make Sure the Wiring will Support an Outlet
IMPORTANT: Before tapping into an existing circuit to add power for an outlet the line must be verified that it is in fact an outlet circuit and not a line use for switching a light fixture or similar application.
- It should be understood where the cable comes from and where it is leading to.
- Once the line is verified it should be checked for available amperage capacity.
- If the new outlet is going to be used as a convenience outlet then the added load may be allowed, however if the new outlet will be powering a microwave oven then the added load will most likely overload the circuit and cause it to trip off.
- Most all microwave ovens require a dedicated circuit.
