3 Phase Pool Pump Wiring

If there is a neutral wire in the conduit or cable supplying the motor it is unused for the motor s three phase wiring.

3 phase pool pump wiring.

The figure we would plug into the calculator would be. Items you must consider are. Wire sizing selection tables. You should have three distinct terminals or wires coming out of the system which allows you to make a connection.

Century swimming pool spa pump motors 56j threaded shaft 208 230 460 volts three phase voltage not common to residences industrial power. The fourth wire is a neutral and the fifth wire is an earth ground wire. Run a phase to each terminal and you should have power within the system. Motor face has 4 threaded bolt holes 3 8 to attach pump to motor.

Three phase submersible pump wiring diagram in the above diagram i showed the l1 l2 l3 and n wire incoming supply with red yellow blue and black. Three phase power is usually found in commercial and industrial facilities where large equipment is operated. It has a longer life span than single phase water pump. There are several factors that must be considered before determining the proper size wire to select for an application.

Cap it with a wire nut. For example use a red wire nut to connect two 12 gauge wires. It vibrates less. Three phase is usually distributed in the wye configuration with five wires.

The incoming supply goes to mccb circuit breaker. Hold the bare ends of the conductors together and twist on a wire nut. Single phase 230 volts 230 1 60 three phase 208 volts 208 3 60 three phase 230 volts 230 3 60 three phase 460 volts 460 3 60 warning. It is more compact and less costly than single phase pump.

In which the red yellow and blue for 3 phases and black color wire for neutral. Wiring any other three phase system will be done exactly the same way. From table 430 150 they draw 40 amps 14 amps and 3 amps respectively. Shaft is 5 8 diameter with threads on end.

Hp 5 hp 75 hp 1 hp 1 5 hp 2 hp 3 hp 5 hp pump wire configuration 2 wire 3 wire phase 1 3 site voltage 115v 230v clear filter cross reference the distance from your pump to the electrical service entrance to determine the correct gauge. Three phase water pump a three phase motor water pump needs three phase power supply it has a simple design with small body size it can be highly efficient with high starting torque. The holes measure 5 7 8 on center measured diagonally across shaft. Three of the wires carry current.
