How to wire open frame relay

30 amp, 2-pole, open frame power relay with enclosure

SPDT relay.... different from DPST contactor.
Both perform same job. Both have 2 sets contacts. Open frame relay SPDT has extra set contacts so a second load can be turned on-off exactly opposite from off-on other load.

Toggle between car charger and water heater or pump, or any 240 volt load.

Use any 15 amp timer, home automation module ... or ordinary 15 amp household toggle switch.

Switch or timer or automation turns the relay on or off. When relay is on, then the NO terminal sends power to car charger. When relay is off, the NC contact sends power to pump, motor, water heater etc.
