Powermatic PJ-882HH Extension cords, Volt, Single Phase Operation, Three Phase Operation

Extension cords

The use of an extension cord is not recommended for the PJ882 Jointer. But if one is necessary, make sure the cord rating is suitable for the amperage listed on the machine’s motor plate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Use the chart in Figure 8 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

230 Volt, Single Phase Operation

As received from the factory, the single-phasemodel of the PJ-882 Jointer is designed to run on 230 volt power only.

The jointer has a grounding plug that looks like the plug illustrated in Figure 9; or you may choose to “hard-wire” the machine directly to a control panel. If hard-wired to a panel, make sure a disconnect is available for the operator. The Jointer must comply with all local and national codes after being wired.

If the Jointer is to be hard-wired, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the Jointer will be connected. Place a warning placard on the fuse holder/circuit breaker to prevent it being turned on while the machine is being wired.

The Jointer with a 230 volt plug should only be connected to an outlet having the same configuration. No adapter is available or should be used with the 230 volt plug.

It is recommended that the single phase jointer be connected to a dedicated, minimum 20 amp circuit with a 20 amp circuit breaker or time delay fuse. Local codes take precedence over recommendations.

Three Phase Operation

The three-phasemodel is factory wired for 230 volt, but can be converted to 460 volt if so desired (see “Converting From 230 Volt to 460 Volt”).

“Hard-wire” the machine directly to a control panel and make sure a disconnect is available for the operator.

If you are hard-wiring the Jointer, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the Jointer will be connected, and place a warning placard on the fuse holder or circuit breaker to prevent it being turned on until wiring is complete.

Figure 9

It is recommended that the three phase jointer, when operated at 230 volts, be connected to a dedicated, minimum 20 amp circuit with a 20 amp circuit breaker or time delay fuse. When operated at 460 volts, connect the jointer to a dedicated, minimum 15 amp circuit with 15 amp circuit breaker or time delay fuse. Local codes take precedence over recommendations.

Converting from 230 Volt to 460 Volt (Three Phase Only)

Consult the wiring diagram inside the starter box cover. A diagram is also included on page 46 of this manual. The Jointer must comply with all local and national codes after being wired.

1.Replace the current contactor with the 460V magnetic contactor (part no. PJ882-526C; purchased separately).

2.Re-connect the incoming leads to the motor for 460 volt operation, as shown in the wiring diagram.

3.If using a plug, install a proper UL/CSA listed plug suitable for 460 volt operation.
