What size main breaker feeding 480v 75 kva transformer?
An exact breaker size can not be given because the voltage, and hence the calculation for current, is not given. A transformer shall be protected by an over current device that is not rated at more that 150% of the primary current.
Size 134 kva cable?
It depends on the current, not the power. There is insufficient information in the question to answer it. Please restate the question.
Can you use a 30 amp disconnect switch for a 30 kva transformer?
im have a 30 kva transformer 3 phase 480v 80 amp panel 120v what size disconnect should I use
Convert 2KW to KVA in single phase?
P=1.73xVxIxCOSO KVA=KW/1.73xCOSO KVA=2000/1.4 KVA=1.42
What wire size is needed for 9.5 kva for amp load?
9.5 Kva is the is the same as 9500 watts. Formula for Amps = Watts/Voltage. As you now can see you didn't give me any voltage so that the amperage can be calculated. Without the amps the wire size can not be calculated. Reply in a discussion if you are interested in an answer.
If you have a circuit breaker box containing 650 amps of circuit breakers it is 3 phase 480 volts what size kva generator do you need?
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.

Would a 15 kva 380 volt generator be big enough to run a house with a 60 amp breaker 380 volts?
A 15 KVA - Generator operating at 380 Volts can cater to only 22.79 Amps. It cannot cater to a 60 Amps breaker
What is the size breaker per phase 200kva generator?
if you have 200 kva so it's 160 KW then ,you need 400 A MCCB and setting at 0.9 and use cable 4c.185 mm2 if the SMDB is nearby and all this will be change according to the ambient temperature and the electrical code used in your area

How do you calculate rated kva of a circuit breaker?
You don't calculate the rated kV.A of a circuit breaker; it's determined by the manufacturer. It's important that a circuit breaker's rated kV.A exceeds the fault level kV.A at the point where the circuit breaker is located, otherwise it may fail to interrupt a fault current and, possibly, self destruct.
What size breaker should be used for 132 KW submersible pump?
400amper Pumps are not rated in KW. I believe you mean kva, or, most likely in my mind, va. Please clarify what you have for a better answer. If you mean 132 kva, which to many people would mean the same thing as 132 KW, you are talking about a pump that is portable only because it is hauled around on a trailer. But that kind of pump wouldn't be submersible and would most likely not be electric. Motors are not often rated in va either, but if what you meant is 132 va, it will run on any common 15 or 20 amp circuit, assuming you connect it to the right voltage.
What is size of power cable of 1137 kva generator?
It depends totally on the voltage used.
10 kva ups 100ah battery how Tobe select cable size?
16mm2
What is the cable size for a 1500 kVA generator with cable length of 50 meters?
35 KVA generator using for load 100 meter length which cable need to used
What is the xlpe for a 34.5kv?
How to compute for the size of wire in the primary side of 2500 kVA transformer 34.5kV
What size of cable wire used for 500 kva transformer 240 volt 3 phase?
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
