How To Make A 20 Amp Circuit

By | July 28, 2022



When it comes to electrical work around the house, most homeowners know that safety is paramount. And that safety begins with following the correct steps to properly make and test a 20 amp circuit. Whether you are replacing an existing circuit or installing a brand new one, making a 20 amp circuit can seem intimidating at first. But with all of the proper tools and materials, you can create your own 20 amp circuit with confidence.

First, make sure you have the necessary tools and materials for a 20 amp circuit including a 20 amp circuit breaker, 12-gauge wire, and appropriate receptacle. Make sure your work area is clear of debris and hazards and always double check to ensure the power is off before you begin any work. With the power off, disconnect the wires from the old circuit, if applicable, and replace them with the 12 gauge wires. Secure the wires to the main panel, making sure that they don’t become loose or overheat.

Next, complete the wiring by attaching the black and white wires to the new 20 amp circuit breaker. Connect the proper receptacle to the wall outlet with the included screws. Then screw in the circuit breaker into the main panel. Make sure it’s securely in place. Carefully insert the two wires that were run earlier into the slots on the circuit breaker. Secure the screws to ensure the breaker is correctly seated.

Now, turn the power back on to your circuit. Check and see if anything looks out of place, then perform a continuity and voltage test using the proper multimeter. If everything passes, the circuit is ready for use.

Making a 20 amp circuit does require some knowledge of electricity, but following a few simple steps can make it a relatively easy job. It’s important to take all necessary safety precautions and be attentive to detail. Following the process outlined here will help ensure that your circuit is built correctly so you can rest assured that it is safe and reliable.
