I have a conveyor belt circuit that has been modified and the demand on the transformer has been increased from 1.5amps to around 3amp. Although protected by a circuit breaker at 2 amps the old transformer got too hot and shorted. What a mess. Anyhow I'm not an electrical engineer, but is there any danger to oversizing a transformer? Going to a 750VA from a 350VA will give me an output amp increase from 1.4A to 3.1A. Does this sound right?? I've searched Google for a quick answer but either it was over my head or dead ends. Thanks guys, Chris.
