It’s important that you turn it off to minimize the risk of working with live wires. You will only need a better wire if you plan on running that said wire over long distances. It’s also normally the largest one, rated for the highest amps. The best wire to use for a 30 amp breaker is a 10-gauge wire. The main breaker is normally separate from the rest, either at the very bottom, top, or to one side. Remove the main panel’s cover and turn the main power switch to the panel off. Lay the rubber mat, wear rubber slippers, and only work with dry hands and tools. Here are the steps to wire a regular (non-GFCI/AFCI) 30-amp single-pole circuit breaker: Step 1: Lay the Mat In some locations, the local authorities expect consumers to use wires ranging from 8AWG to 10AWG for 30A breakers. Wiring a 30-Amp Single-Pole Circuit Breaker If you install a new 30-amp circuit breaker, ensure the wiring and all outlets on its circuit can handle up to 30 amps of current. If you’re replacing an existing one, you will remove it in Step 3 before replacing it with the new one. If you live in an average home with ordinary appliances like TVs, heaters, and. 20-amp circuits are the norm, along with 15 amps circuits. That includes 15,000 BTU AC units, which use an average of 2,000 watts, space heaters (1,200 watts), microwave ovens (1,200 watts), and cookers (1,500 watts). The procedure described below assumes that your panel has enough capacity and space for a 30-amp circuit breaker. 20A is the equivalent of 2,400 watts (120V). For safety: safety gloves and rubber slippers or mat.Tools: Electrical tester or screwdriver, pliers, and a wire stripper.Main item: A 30-amp single-pole circuit breaker.You will need the following to wire a 30-amp single pole circuit breaker: Don’t attempt to use it on circuits with thinner wire or to replace a circuit breaker with fewer amps. It is normally used for a heavy appliance that requires 110-120 volts to operate, not 220-240 volts, for which you will need a double-pole breaker instead.Īlso, it should only be fitted on a circuit with at least 10 gauge (10/2) wiring (8 gauge for long distances). However, it is designed to cope with a larger load, which means a higher current, up to a maximum of 24-30 amps (or 2,880 watts of power). A 30-amp single-pole circuit breaker looks similar to a regular circuit breaker with fewer amps.
