How do you determine amperage service for a 240V single-phase three-wire system what formula do i follow?
You have to know the maximum amps you wish to deliver or draw of the device or devices you wish to power. There are charts on the internet for wire gauges and distance that you can follow. For example:
A 12 gauge wire will handle 20 amps safely for runs up to 100 feet. You go down 1 gauge for runs over 100 feet. So if you are running 175 feet at 20 amps you should use 10 gauge so voltage drops don't occur.
Voltage has no effect on rated current output other than selecting a wire or cable that is rated for the working voltages. 20 amps at 240 volts is the same as 20 amps at 120 volts. As long as the wire is rated at 240 volts, it will carry 20 amps at voltages less than 240 the same.

What is amperage input of transformer on 208 3 phase?
The amperage input of a transformer on a 208V three-phase system can be calculated using the formula: Amperage (A) = Power (Watts) / (Voltage (V) x √3). To determine the amperage, you need to know the power rating of the transformer in watts (or kilowatts). Once you have that, you can plug the values into the formula to find the input amperage.
How many amps is 24V 200AH?
To determine the amperage for a 24V 200AH battery, you use the formula: Amperage = Capacity (AH) / Voltage (V) So for a 24V 200AH battery: Amperage = 200AH / 24V = 8.33 amps
What is the amperage of a 20kw heater?
To determine the amperage of a 20 kW heater, you can use the formula: Amperage (A) = Power (W) / Voltage (V). For example, at a standard voltage of 240 volts, the amperage would be approximately 83.3 amps (20,000 W / 240 V). If the heater operates at a different voltage, simply adjust the calculation accordingly.
How many amps does an electric roaster use?
The amperage of an electric roaster can vary depending on its size and wattage. To calculate the amperage, you can use the formula: Amperage = Wattage / Voltage. For example, if a roaster has a wattage rating of 1200W and operates on a standard 120V outlet, the amperage would be 10A (1200W / 120V = 10A). It's important to check the specific wattage and voltage requirements of your electric roaster to determine the exact amperage it uses.
What is the formula to get the ampere using a 12 volts?
To obtain amperage from a formula you need at least two components. Formula for amperage are I = W/E, I = E/R and I = sq root of W/R.
How many amps in a 1500 mccullough generator?
To determine the amperage of a generator, you will need to know the output voltage as well. Once you have that information, you can use the formula: Amperage = Watts / Voltage. For example, if the 1500 watt McCullough generator outputs 120 volts, then the amperage would be 12.5 amps (1500 watts / 120 volts).
How many amps is a 2000KVA trans good for?
To determine the amperage capacity of a 2000KVA transformer, you would need additional information such as the voltage at which it operates. To calculate the amperage, you can use the formula: Amperes = KVA / (1.73 x kV), where 1.73 is the square root of 3.
If a heater takes 1200 watts at 120 VOLTS what would the amperage be?
I don’t know
How many amps is 1.5 kilowatts?
To convert kilowatts to amperes, you need to know the voltage of the circuit. Without the voltage, you cannot determine the amperage. Use the formula: Amperes = Kilowatts / Volts.
How many amp in 10000watt 240 volts?
To calculate the amperage, you can use the formula: Amperage = Watts / Volts. Thus, for 10,000 watts at 240 volts, the amperage would be 41.67 Amps.
How much amperage can a 60-VA transformer put out?
To determine the amperage output of a transformer, you need to know the voltage it operates at. Assuming a standard voltage of 120 volts for a household transformer, you can use the formula Amperage = VA / Voltage. In this case, a 60-VA transformer operating at 120 volts would output 0.5 amperes (A) of current.
If you have 500 ohms and 2000 watts how do you find amps?
The formula you are looking for is I = sq root of W/R.
