Tell me which transformer very specifically, and in great detail.
Send me photo's close ups and shots from 5 feet away so i can put it all in context.
Use the 'attach files' link at the bottom left of your reply box.
We can go from there.

It's the transformer located on the furnace

Thanks for the pictures, can you post pictures of the burnt wires you mentioned earlier?...and a clear well focused picture of the unit wiring diagram with a tiny red mark on the wire that burned,
Next you will need a clamp around amp meter to check the amperage draw on the wire that was burnt.

I clipped that wire earlier in the day. But it was the white wire that hooks on to the bottom of the contactor. It's also dark right now in Ga.

I'm sorry it's the 240v wire
Expert:  Phil replied 1 year ago.
I need a wiring diagram, the burnt wire could be caused by a loose wire connection, but the breaker tripping can only be caused by a dead short somewhere.
I need a photo of the wiring diagram to coach you on that.
we can continue tomorrow. you will need a clamp around amp meter as well,
