Thanks for your electrical wiring question William.

How to Add Circuits to an Electrical Panel

electric panel circuits

Skill Level: Intermediate to Advanced – Best installed by a Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools, electric drill,  auger bits and extension cord.
Estimated Time: Depends on personal level experience, ability to work with tools and install electrical circuit wiring.
Precaution: Identify the panel circuit, turn it OFF and Tag it with a Note before working with the wiring. Working in electrical panels is dangerous and not recommended for unqualified individuals.
Notice: Installing additional circuit wiring should be done according to electrical codes,  with a permit, and all work should be inspected by the local building authority.

    Tom,
    It all depends on what the circuit will be used for, the location, and the loads placed on the circuit. For example, you may install 10 receptacles in your garage on one 20 amp gfci circuit as long as the circuit will not become overloaded, ideally being loaded to 80% of the circuit capacity. The NEC Code specifies circuit requirements for specific rooms and equipment such as a dedicated gfci circuit which is required for bathroom receptacles. The kitchen has several codes related to circuit requirements as well. So circuit sizing always begins with the application and what the electrical code specifies for the circuit.

    What is a proper way to decide how many receptacles can be wired to a 20 amp circuit.
    Thanks Tom
