How many watts will a 20 amp two pole breaker handle?
Answer for USA, Canada and countries running a 60 Hz power supply service. Watts= voltage X amps At 120 volt total watts would be 2400 at 20 amps. The electrical code states that circuit conductors that are fed by this breaker on a continuous load can only be loaded to 80%. #12 wire rated at 20 amps, derated to 16 amps continuous = 16 x 120 = 1920 watts, #10 wire rated at 30 amps derated to 24 amps continuous = 24 x 120 = 2880 watts. On load calculations this derate should be taken into consideration. To maintain the required wattage needed for the load the wire size and/or the next size breaker may be needed.
How many loads can a 20 amp 12 ga wire carry?
A #12 wire can carry 20 amps. Assuming the connected voltage is 120 volts the wattage will be Watts = Amps x Volts. W = 20 x 120 = 2400 watts. The circuit can legally be loaded to 80%. 2400 x 80% = 1920 watts. The maximum amount of loads that can be connected to a 20 amp #12 wire have to be added up individually but stay under 1920 watts.
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.
A 208V water heater can te be replaced by a 240V water heater?
Yes but you will not get the full watt rating out of the tank. Watts = amps x volts. Say the tank draws 20 amps. 20A x 240V = 4800 watts. 20A x 208V = 4160 watts. It will take longer to heat your water with less wattage.
How many amperes does a 20 watt compact fluorescent lamp draw?
To answer this question the voltage has to be given. I = W/E. Amps = Watts/Voltage.
