Quick Answer: How many amps does a 45 kva transformer put out?

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 do I convert kVA to amps?

Calculation with line to line voltage

  1. S(kVA) = √3 × I(A) × VL-L(V) / 1000.
  2. So kilovolt-amps are equal to √3 times amps times volts divided by 1000.
  3. kilovolt-amps = √3 × amps × volts / 1000.
  4. kVA = √3 × A ⋅ V / 1000.
  5. S = √3 × 12A × 190V / 1000 = 3.949kVA.
