SpletIf you short the R wire to the C wire, you've effectively created a very low resistance closed circuit across the secondary of the 24V transformer in the HVAC system. This causes the current in the circuit to be high, which may quickly overheat the wires. In a typical household circuit, the circuit would be protected by a circuit breaker (or fuse) which is designed to …
