How to size a step down transformer

WebIf a transformer needs to step-up 240 volts to 480 volts, and you need a maximum current capacity of 40 amps, you must first calculate the number of amps needed to comply with electrical codes. If the codes require a maximum usage of 70 percent of the transformer's capacity, multiply 40 times 1.43. WebJul 31, 2024 · If your transformer is rated at 1.5 kVA, and you want to operate it at 25 volts, multiply 1.5 by 1,000 to get 1,500 and then divide 1,500 by 25 to get 60. Your transformer will allow you to run it with up to 60 amperes of current.
