What happens if you wire a double pole thermostat wrong?

With a double pole (4-wire) thermostat, you’ll have either 4 wires or 4 terminal screws. If it’s terminal screws, two of them will be marked L1 and L2 or Line 1 and Line 2. These normally go to the incoming 240 volt power. If you get it wrong, you’ll trip the breaker and/or destroy the thermostat.
