• Idler Motor: 2/0 AWG COPPER
• Breaker/Fuse: 150 MIN / 400 MAX

Product Usage Instructions

Power Requirements

Before installation, call your electric company to verify the KVA size of the transformer. The KVA number should be larger than the HP of the idler motor.

Checking Connections

Check all connections to ensure they are secure, including factory connections to the power block. It is recommended to recheck connections after a few weeks of using the converter.

Speed Control

If you experience any issues with the speed of the phase converter, shut it down immediately. If you don’t understand how to troubleshoot the issue, contact us or a qualified electrician. Failure to turn off the unit may result in damage to the idler motor, which will not be covered under warranty.

Breaker and Fuse Sizes

For motors, double the amps size of the machine. For example, if the equipment pulls 20 amps, use a 40 amp breaker. When multiple machines will run at the same time, calculate the total amps by adding the amps of the largest machine and the other machines. Use the next standard size breaker for this total amperage.

Wire and Breaker Sizes

For single-phase wiring, use 300 MCM Copper for distances under 50 feet. The idler motor requires 2/0 AWG COPPER wiring. The breaker/fuse should be a minimum of 150 amps and a maximum of 400 amps.

Wiring Diagram

Refer to the wiring diagram located inside the connection cover or on the nameplate of the idler/generator motor. Follow the specific instructions for connecting the wires based on the motor’s lead numbers and the L1, L2, and L3 terminals.

Load Center and Breaker Panel

If using a load center or a 3-phase breaker panel, make sure to size the motor load breaker twice the full load amps of your equipment.

Enclosure Dimensions

The Nema 4 enclosure dimensions for GP50, GP60, GP75, and GP100 models are as follows:

• A: Dimension
• B: Dimension
• C: Dimension
• D: Dimension
• E: Dimension
• F: Dimension

READ FIRST – BEFORE INSTALLATION

A most important step to know.

• NEVER Start the phase converter with a load, this includes transformers.

• Make sure you have the incoming service to start the phase converter, call your electric company to verify the KVA size of the transformer, the KVA number should be larger than the HP of the idler motor.

• DO NOT use WIRE NUTS for any connection, use the bolt-down lugs. Check to make sure all connections even factory connections to the power block are secure, also recheck connections after a few weeks of using the converter.

• When powering up the unit, if the idler does NOT come up to FULL SPEED, then shut the phase converter down right away. If you don’t understand then call us or a qualified electrician. if you do not turn the unit off you have a chance
  to damage the idler motor that will not be covered under warranty.

• Must be installed by a licensed industrial electrician, our guidelines are not to supersede local and state laws.

Power requirements

• You will need to use a motor load-type breaker. NOT a quick blow or trip breaker.
• Sizing a breaker for a single machine with an inductive load (motors) doubles the amps size of the machine. For example, if the equipment pulls 20 amps use a 40 amp breaker.
• Sizing the equipment for multiple machines double the amp of the largest machine and add the the other machine that will run at the same time. Example; 20 AMP Lathe. 9 amp saw, 6 amp milling machine. 20 X 2 = 40 +9 + 6 = 45 amps, use the next standard size breaker which would be 50 Amps two pole breaker.
• Use the chart to make sure you don’t go over or under the Minimum and maximum size allowed. For rural areas increase the minimum size breaker by 20% Click on the next picture to see this chart.

Mounting the Phase Converter Panel

Mount the enclosure first, to a non-vibrating surface, there are two options provided for mounting, next install the back plate with the four nuts provided. Mounting the phase converter panel near the breaker panel is recommended the larger wire is your single phase line, so that is best to keep as short as possible.

Every 50 feet you will need to increase the size of the single-phase wire.

FAQ

Q: What is the power requirement for this phase converter?

A: The power requirement for this phase converter is 230 Volts – 300 AMP SERVICE.

Q: What wire and breaker sizes should I use?

A: For single-phase wiring, use 300 MCM Copper for distances under 50 feet. The idler motor requires 2/0 AWG COPPER wiring. The breaker/fuse should be a minimum of 150 amps and a maximum of 400 amps.

Q: How should I connect the wires to the motor?

A: Refer to the wiring diagram located inside the connection cover or on the nameplate of the idler/generator motor. Follow the specific instructions for connecting the wires based on the motor’s lead numbers and the L1, L2, and L3 terminals.
