The formula to use is I = W/E, assuming that the single breaker is delivering 120 volts, the amperage to the circuit is 16.6 amps. A continuous load on a 20 amp breaker has to be reduced to 80% according to the electrical code. 20 x .8 = 16. So to answer the question, yes, a 20 amp breaker will support a 2000 watt load at 120 volts.

What is the wire size required for 1800 watts for lamps?
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp breaker.
How many watts can a double 30 amp breaker switch handle?
The maximum wattage that a 30 amp breaker can handle is 30 x 230 = 6900 watts. Other variables come into play and this number will decrease depending on the load, duty time, and difference in voltage fluctuation.
What amp breaker should you use with 3700 watt element?
To determine the appropriate amp breaker for a 3700-watt element, you can use the formula: Amps = Watts / Volts. Assuming a standard voltage of 240 volts, the calculation would be 3700 watts / 240 volts = approximately 15.4 amps. It is advisable to use a 20-amp breaker for safety and to accommodate any inrush current, ensuring the breaker can handle the load without tripping.
Can you use 14 wire for a light off a 20 amp circuit?
Yes, in home wiring as long as it is protected by a 15 amp breaker. Remember this circuit will only handle 1800 watts and cannot be loaded to any more than 1440 watts. So if each light is 75 watts then the maximum you can install is 19.
What size amp circuit breaker would protect a 12kW boiler?
The breaker protects the wiring not the boiler. 12,000 watts at 240 volts will require 50 amps. So, you will need a 60 amp breaker using AWG# 6 wire on a dedicated circuit.
