3 phase air compressor pressure switch wiring diagram. The wiring procedure may or may not call for a neutral wire. It has a dayton motor with the following specs. It shows the elements of the circuit as simplified shapes as well as the power and signal links in between the devices. The red wire from the 3 phase is only connected to the motor. Youll typically need three short strands of wire of the recommended gauge one black one white and one green or bare for the ground. This method will work for any pump that runs directly off of a pressure switch including jet pumps well.
If the switch isnt connected to the motor consult the manual for the wiring diagram for the air compressor motor. In this video we show you the best way to a pressure switch for 115v and 230v pumps. We are using a 3 phase 240 volt system and hooking up to an air compressor. A wiring diagram is a simplified traditional photographic depiction of an electric circuit. Variety of air compressor wiring diagram 230v 1 phase. The switch may be wired correctly yet if a full path the motor allows the compressor to cut in when the pressure is low cut out when the pressure is at the stopping point the compressor stops and thats repeatable without the switch in the circuit and then when you add the switch there doesnt appear to be enough power to drive the.
The black and blue wires from the 3 phase are connected to the pressure switch and then connected to the motor. All 230v appliances must be connected to a dedicated circuit powered by a double pole circuit breaker with the proper amperage rating. Before you wire a 230v air compressor you should always check the manual for the proper wire gauge. I recently got for free a speedaire model 3z582 single stage ccw 3hp 3 phase air compressor. We used a pressure switch by square d part number 9013 fhg12mix. According to the spec plate it pulls 82 amps at 230 volts.
Model 3n085 3 hp 3 phase 3495 rpm motor.
