WebJan 13, 2024 · In a single-phase, 240V HVAC system, the surge protector is connected to the two “hot” voltage legs, L1 and L2, and to the ground terminal. Under normal conditions, the surge protector allows only the tiniest amount of current to trickle to ground. But when a spike in voltage occurs, resistance drops almost instantaneously.
WebMany different supply voltages are used in the HVAC/R industry, ranging from 575-V, three-phase power supplies to 24-V control circuit voltages. Power supplies may be indicated by solid lines or by dashed or dotted lines. Fig.7 B- Wiring: Most schematics use straight lines to represent the wires that connect components to each other.
