Assuming that the figures you supply in your question are line values, and not phase values, and each line current is identical, then you can find the total apparent power (in kV.A ) by applying the following equation:

apparent power = 1.732 VL IL

If, then, by 'per leg', you mean 'per phase', then all you need to do is to divide your answer by 3.

Incidentally, the correct symbols are 'kV.A', not 'kva', 'V' not 'v', and 'A' not 'amp'. lin

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.

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.

Will a 20A 240V breaker be sufficient for a 240V 22A input welder or do you need to go to a 30A?

It would have to be a 30 amp breaker to use the full power of the welder. I'd say go with the 30A. The general rule is that your planned load should only be 80% of the circuit capacity. That means a 30A circuit should have a maximum load of of (30*0.8) = 24A. With the 30 amp breaker you must have at least #10 wires feeding the circuit.


How many amps equal 1 circuit?

80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.

Absoluteyl not.


What is Op-Amp non inverting amplifier?

When the feedback of the output terminal of an Op-Amp is given to the non-inverting terminal [pin 3 for IC-741] of that Op-Amp , then , that circuit is called non-inverting amplifier using Op-Amp. This circuit is called non-inverting because the output signal of this circuit is in phase with the input signal.


Would there be any problems powering on a 16 amp single phase device from a 32 amp three phase circuit?

if it is connected correctly it will run. However, you may want to modify the circuit to confirm to the NEC so you may protect the device from overloading and burring up!for example you may use the 32Amp circuit as a sub-panel!


How many 5 amp TVs can be plugged into a open circuit?

You can plug in as many as you want but none of them will work. An "open" circuit is an electrical circuit which is not a complete circuit and therefore electricity will not flow through it. If you mean an unused circuit,which has no load on it, then the answer is 2 ea. 5 amp devices on a 15 amp circuit and 3 ea. 5 amp devices on a 20 amp circuit. The reason for this is that any circuit is not to be "loaded" more than 80% of the OCPD (circuit breaker amperage rating.

Can a 240v 50amp circuit be changed to a 120v 30amp circuit?

Answer for USA, Canada and countries running a 60 Hertz supply service.Yes, a 240v 50amp circuit can be changed to a 120v 30amp circuit. The wire for the 50 amp circuit should be a #6. This is more than ample for a 30 amp circuit. Remove the two pole 60 amp breaker and replace it with a single pole 30 and a single pole 15 amp breaker. One of the two #6 wires will be terminated on the neutral bus (if there is a white use it) and the other #6 will be terminated on the new 30 amp breaker. This will give you the required 120 volt 30 amp circuit. The new 15 amp breaker that was installed just to fill the hole from the two pole 60 amp breaker will give you a spare 15 amp circuit. I have no idea what you are trying to do, but there is no way you can change 220v 50 amp to 120v 30 amp. You can take 220 volt input in the top of your circuit breaker box. Then half of one side will be 120v and half of the other side will be 120v. You can install a 30 amp fuse. You should hire an electrician.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
