Here are some FAQs regarding your kVA:

Q) What's the difference between KVA and VA rating?
A) 1 KVA = 1000 Volt Amps. Therefore a 2500 VA transformer would be listed as 2.5 KVA.

Q) I don't see my specific KVA listed?
A) We have listed the most common KVA requirements. It is commonly acceptable to oversize your transformer to the next largest size listed. For example, if you require a 2.5 KVA transformer you should select a 3 KVA transformer, or if you require a 40 KVA transformer you should select 45 KVA. Make sure to size the associated circuit breaker appropriately.
