I have a HVAC which is having a 24V 40VAC transformer. I might have shorted the output of the transformer while working on the wires.
I noticed that the fuses on the input side of transformer blew off and I replaced them with time delay 2A fuses. I unloaded the output of transformer (open circuit) to test if transformer is providing the right volts. Here the fuses blew off again.
Is it because the transformer is bad or I am using wrong fuses here ?
Transformer: Input: 240V Output: 24V 40VAC
