- Central Air Conditioner – 3500 Watts. Central A/C Fan Only – Compressor Off – 750 Watts. Largest Window Units – 1440 Watts. Medium Window Unit – 900 Watts.
- Homeowners can often power most household appliances using between 3000 and 6500 watts. If your home has a smaller furnace and city water, you can generally expect that 3000-5000 watts will cover your needs. If you have a larger furnace and/or a well pump, you will likely need a 5000 to 6500 watt generator.
- Depending on the tonnage of the AC and heat load in a room, an AC would consume about 1 to 2 units of electricity in an hour. A 1 kW Solar PV Panel would produce about 5-7 units in a day, which can get consumed in 4-5 hours of continuous running of an air conditioner.
A 1500 Watt heater will cost the same to run whether it is 120 or 240 Volt. 240 Volt heating circuits are more common because, as the chart shows, you can place more heaters on a 20 Amp 240 Volt circuit (maximum of 3840 Watts) versus a 120 Volt circuit (maximum of 1920 Watts). 6.
- For 20 AMP you have 20A*120V or 2400 watts and 15 AMP you have 15A*120V or 1800 watts. Good Electricians will only plan for 80% load so you have 1920 and 1440 watts respectively at your disposal per circuit. Next, find out what's on the circuit. To do this, leave the lights on that you want to connect to.
- Given values: Watts=1500; volts=120; Problem: Amps=? Answer: Amps = Watts/Volts. => 1500/120 => 12.5 Amps Answer is:12.5 Related Calculator : Horsepower to Amps Unit Calculator.
- Quick calculation to find watts: Volts * Amps = Watts, so 5V * 2.4 amps = 12 watts.
Wire Gauge and Ampacity
|Wire Use||Rated Ampacity||Wire Gauge|
|Electric Clothes Dryers, 220-volt Window Air Conditioners, Built-in Ovens, Electric Water Heaters||30 Amps||10 Gauge|
|Cook Tops||45 Amps||8 Gauge|
|Electric Furnaces, Large Electric Heaters||60 Amps||6 Gauge|
|Electric Furnaces, Large Electric Water Heaters, Sub Panels||80 Amps||4 Gauge|
- The 30-amp service for an RV is 120-volt with a 3 prong receptacle and a single 30-amp dedicated breaker. The 30 AMP is a standard ANSI C73.13, TT-30P (plug) / TT-30R (receptacle).
- It is a misconception that this 50-amp RV service is something special. This service is a STANDARD 120/240 50-amp 3 pole with 4 prongs used for numerous applications. Each leg is 50 amps @ 120 volts. 50-amp X 120-volt = 6000 watts.
