What size breaker do I need for a 45 kVA transformer?
For a 45kVA transformer, 125A×1.25=156A, so use a 175A protection device.
How many amps can a 100va transformer handle?
A transformer with a 100 VA rating, for instance, can handle 100 volts at one ampere (amp) of current. The kVA unit represents kilovolt-amperes, or 1,000 volt-amperes. A transformer with a 1.0 kVA rating is the same as a transformer with a 1,000 VA rating and can handle 100 volts at 10 amps of current.
How many kVA is a 200 amp service?
With your load single phase of 200 amps at 240 volts (which is what you have coming into you home) gives you 48 KVA. This means that a 50 KVA should work.
How many amps is 50kva?
kVA to amperes, table for conversion, equivalence, transformation (3F, 220Volt) :
|How many kVA are:||Ampere Equivalence|
|2 kVA||5.25 Amp.|
|3 kVA||7.87 Amp.|
|4 kVA||10.50 Amp.|
|5 kVA||13.12 Amp.|
How many amps is 30kva?

How many amps is a 50 kva transformer good for?
Three Phase Transformer
How many kVA is 40 amps?
Amp. to kVA, table for conversion, equivalence, transformation (Voltage = 220, AC, 3F):
|How many Amps are:||Equivalence in kVA|
|10 Amps||Equivalent to 3.81 kVA|
|20 Amps||7.62 kVA|
|30 Amps||11.43 kVA|
|40 Amps||15.24 kVA|
How do I convert kVA to amps?
Calculation with line to line voltage
- S(kVA) = √3 × I(A) × VL-L(V) / 1000.
- So kilovolt-amps are equal to √3 times amps times volts divided by 1000.
- kilovolt-amps = √3 × amps × volts / 1000.
- kVA = √3 × A ⋅ V / 1000.
- S = √3 × 12A × 190V / 1000 = 3.949kVA.
