Occupy two slots on a breaker panel and protect two energized wires. Consist of two single-pole breakers with one handle and a shared trip mechanism. Supply 120V/240V or 240V to a circuit. Range in capacity from 15 to 200 amps. Are required for large appliances such as dryers and water heaters. Do not add together the amperage of the two breakers. Both circuits will be tripped simultaneously by the amperage displayed on one circuit breaker handle. For example, a two-pole breaker at 15 amps on each pole (breaker handle) would supply 240 volts to the appliance on that branch at up to 15 amps, not 30. If no wattage rating is displayed, the load can be calculated by multiplying the amps drawn (appliance amps) by the voltage of the circuit. If neither the amps nor the wattage ratings for a device is known, the chart below lists common household appliances and the average watts drawn for each to aid in calculating the load of a circuit. used when figuring electrical material needs and is already calculated in the chart.

Lighting circuits may be designed for only 15 amps; To calculate the load requirement for a circuit, first add up the wattage of all the electrical devices that will be on the circuit. Then, divide the total wattage by the voltage of the system, typically 120 or 240, and that will give you the required current or amps.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical The circuit breaker is labeled with the rated current in amperes, but excluding the unit symbol, A. Instead, the ampere figure is preceded by a letter Power is supplied to your home, from the utility, in the form of volts and amps. Circuit breakers (Figure 4) perform the same function although they work in a 120 Volt heaters require 1-Pole circuit breakers; 240 Volt heaters need 2-Pole as the chart shows, you can place more heaters on a 20 Amp 240 Volt circuit 12-gauge wire is the next size larger and is allowed to carry up to 20 amps. As a result, the amp rating of a circuit breaker has the following relation to the wire size The standard ampere ratings for fuses and inverse time circuit breakers shall be 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000, 5000, and 6000 amperes.

One clue to circuit sleuthing is the amperage (amp) rating of the circuit. This is the number printed on the circuit toggle lever or nearby. There are common amp ratings for various appliances and devices; if an appliance is rated for 20 amps, for example, you'll know it's not powered by a 15-amp circuit (or at least it shouldn't be). If no wattage rating is displayed, the load can be calculated by multiplying the amps drawn (appliance amps) by the voltage of the circuit. If neither the amps nor the wattage ratings for a device is known, the chart below lists common household appliances and the average watts drawn for each to aid in calculating the load of a circuit.
