   Instead of 12 AWG copper and 20 amperes breakers, you'll need 10 AWG and 30 ampere breakers. So if you want to use the 12 AWG copper conductors and 20 ampere breakers, you'll have to install a 3840 Watt or smaller heater.

   How much current can a 20 amp breaker run?

   • Example: If you have a 20 amp breaker, you can only allow for a 16A current. 16A is 80% of the max. the specified ampacity of the circuit breaker. This is a safety measure; you better have a bit of overhead to prevent the circuit from frying. You can read the full Article 240.4 (B) in NEC 2014 on this here.

   How much wattage is a 20amp breaker?

   • In Canada and in the United States (If i am not mistaken) total wattage is (A x W) x 80%.This goes to say, a double pole bridged 20amp breaker would be consider 40AMP. So 40AMPS x 120 (Or corresponding voltage) x 80% = 4800 X .80 = 3840 would be the maximum voltage.

   How many amps does a 3000 watt breaker use?

   • Namely, if you run a 3,000W unit on a 220V circuit, the current is calculated like this: 3,000W / 220V = 13.63 amps. You can calculate the amp draw from wattage and voltage. If you know how to calculate the amps and account for the 80% breaker rule, you can calculate the size of the breaker yourself.

   What is a wattage breaker?

   • In all of the universe, Wattage (W) is Voltage (V) * Current (A or I). Nowhere in the universe does a 20 ampere breaker give you 40 amperes. In the US (and maybe Canada), branch-circuit conductors and overcurrent devices for fixed electric space-heating equipment must have an ampacity not less than 125% of the total heating load.

   The next breaker size is 20 amps; that means we need to use a 20A breaker for a 1,500W space heater running on 120V standard circuit. A standard 1,500W space heater on a 120V circuit requires a 20A breaker.
