How many amps can a 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 do you calculate the amperage of a transformer?
If for some reason you need a larger transformer to operate appliances, you still divide the wattage by the voltage to find the current. For a 120-volt primary, 2000-watt transformer, divide 2000 by 120 for the current (2000 Watts /120 volts =16.67 amps). For a 240-volt, 3000-watt transformer, the current is 12.5 amps.

What happens when transformer is overloaded?
As a transformer heats up, the high temperatures can gradually weaken the insulation system. The weakening of the system will happen faster if the transformer is frequently overloaded. Overloading causes overheating, and eventually thermal degradation that acts thrrough cracks in the insulation.
What is the capacity of a transformer?
Capacity: Transformers are rated to carry a load, which is indicated by their kilovolt-amperes nameplate ratings at the rated output voltage and frequency. These are standard within the industry and include: 15, 30, 45, 75, 112.5, 150, 225, 300, 500, 750, and 1,000 kVA.
