A 240V load drawing 7A placed on a transformer rated 1,500 VA with 240V output would cause the transformer to be ...

Explanation:
Transformers have a rating in VA that defines the maximum apparent power they can deliver at the rated voltage. At 240 V, the transformer’s limit is 1500 VA, which means it can supply about 6.25 A (1500 VA ÷ 240 V). If the load draws 7 A at 240 V, the apparent power required is 240 V × 7 A = 1680 VA, which is higher than the transformer's 1500 VA rating. Because the load needs more power than the transformer can safely provide, the transformer would be overloaded. Overloading often causes overheating and voltage sag, and it can trip protective devices.
