If a 240v circuit hsa 30 amps per phase what is the amperage 30 or 60?

Still 30 amps, but at 240 V you'll have twice the watts that you would on a 120 V, 30 amp circuit, and after all, watts are what actually does the work.

What amperage will a range with a rating of 12.9 kw draw?
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?
10 Amps. Amps=Watts/Volts
How many Amps for 3 horsepower at 208 volts?
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
If you have an electrical circuit of 15 amps how many amp's are on the neutral?
15 amps out and 15 amps back... unless there is a ground fault, but if that's the case you should shut down the device anyway.The answer above applies to the U.S. and Canada for 120 volt load or for a European 240V load.Note that in North America 240V it is different: For a US or Canada 240 volt load or a balanced three-phase load, there is no current flowing in the neutral.
What is the amperage rating of the mission essential power MEP circuit breaker of the secondary distribution center?
200 amps
What is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
What do amps measure in a circuit?
Amperage or Amps is a measure of is the flow rate of electrical current that is available.
What is the amperage for a circuit with 2 60amps lights and 120volts?
60 amps
What is the rating of circuit breaker needed for a 500kva load?
To answer this question a voltage needs to be stated and whether the load is three phase or single phase. Without the voltage the amperage can not be calculated. For single phase, Amps = kva x 1000/voltage, for three phase, Amps = kva x 1000/1.73 x voltage.
Does a 10amp 240v appliance draw 5 amps per phase?
Answer for USA, Canada and countries running a 60 Hz supply service.No. Even though 240 volts uses two breakers it is still classed as a single phase service. Kirchhoff's law states that current entering a circuit is equal to current leaving the circuit. Since the appliance draws 10 amps, the whole circuit has 10 amps flowing through it.
What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?
10 Amps. Amps=Watts/Volts
What amperage will a range with a rating of 12.9 kw draw?
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
What is the amperage for a 20000 volt-amp heating unit on a 240 volt single phase circuit?
Volt amps is the same way of saying watts. This is seen in the formula Watts = Volts x Amps. Using the formula I = W/E we transpose I = 20000/240 = 83.33 amps.
How do you measure amps on a 208V single phase circuit with a clamp on amp meter?
Clamp the meter around the energized conductor that is connected to the load to be measured and read the amperage off of the dial face of the meter.
Wh would someone divide16.4kva by 480v?
Answer: To determine the amperage in a circuit. Notes: Power (in watts) = Volts * Amps 16.4 KVA = 480V * Amps 16400 / 480 = Amps ~34.2 = Amps
How many Amps for 3 horsepower at 208 volts?

This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
What size wire for 55kw?
Wire is sized by the amperage that it will carry. 5 kW is 5000 watts. The equation to find watts is W = Amps x Volts. The equation to find amps is Amps = Watts/Volts. As you can see a voltage is needed to calculate the amperage. Once the amperage is stated, the wire size can be given for that particular amperage.
