What size breaker feeds a 45 kVA transformer?
70-ampere
A three-phase, 480-volt, delta-connected 45kVA transformer protected by a 70-ampere circuit breaker supplies two feeders not more than 25 feet in length.
How many amps can a 100va transformer handle?
one ampere
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.

How many amps can a 40 VA transformer handle?
1.66 Amps
Knowing that a 40VA transformer will produce 24 volts, Ohms law can be used to determine what amperage the transformer can operate at before burning up. 40 Watts / 24 Volts = 1.66 Amps.
