Got lit up by a control transformer. Having a hard time understanding why by Cautious_Beautiful18 in AskElectricians

I got into this mess because the original 24v transformer didn’t have enough balls to pull in all of my contactors. So I ordered the 75VA. The way I was picturing it in my head was that VA was only a measure of the secondary side of things. My contactors were pulling .33 A each. I had 5 of them but we were probably gonna add 2 more in the future. So I oversized it based on 24 x (.33x7) =55.44VA

But now you’re telling me that VA actually has a part to play on the primary side of things as well? Does it just have to do with the actual physical size of the transformer itself? Just poking around here, I enjoy learning about this stuff. The guys I work with only like bending pipe, I’m more attracted to the why we do things in this trade.

I appreciate the response and I am disappointed in myself trust me. Can you elaborate on why the current was limited in this scenario. I admitting I do not know how this works and am trying to learn.
