You see, the tandem breaker is a divided single-pole breaker, servicing two different circuits. Avoid using an incorrect gauge, for it can cause a precarious situation when an appliance tries to draw more current from the circuit than the wiring gauge can handle. Using this simple relationship principle, you can calculate the available wattage of any given circuit size: 15-amp 120-volt circuit: 15 amps x 120 volts = 1,800 watts. For a two-hundred-watt heater, a 15-amp circuit breaker will be sufficient. More Options Available $ 18 87 (781) Model# BR220. This breaker size is perfect for carrying loads in a single area in a typical household. To determine the size of the subpanel's feeder breaker, converting the total value of 8,000 watts to amps is needed. For aluminum wires on 50-amps, the wire gauge requirement is four. This may not provide a convenient branch-circuit total load, but it avoids the risk of trying to use a clamping ammeter on live wires inside a breaker panel. Using this simple relationship principle, you can calculate the available wattage of any given circuit size: The simple A x V = W formula can be restated in a number of ways, such as W V = A, or W A = V. Choosing the correct size for a dedicated appliance circuit involves fairly simple arithmetic to make sure that the appliance's electrical demand is well within the capacity of the circuit.
