All HOLTEC systems that have an electrical motor require a FUSED DISCONNECT which provides a supply of 460 VOLTS (+/- 5%), 3-PHASE with the proper AMPERAGE as provided specifically in your quotation or order confirmation.

Your voltage cannot exceed +/- 5% of the 460 VOLT REQUIREMENT, which means a variance of no less than 440 Volts and no greater than 480 Volts as your primary power input.

If your power source does not meet this requirement, it will be your responsibility to purchase a step-up or step-down transformer to ensure that the system current is conditioned and fed to this specification.

The main fused disconnect which supplies this power should have sufficient conduit or cord to be connected at the middle point of the HOLTEC system location prior to our final delivery.

This main disconnect will be used to supply power to a starter which employs the star-delta (Y-Δ) configuration method for starting the motor.  With this design, once the motor reaches a certain speed, it changes from a “star” configuration to a “delta” configuration to ensure the primary motor operates efficiently. The star-delta design also reduces starting current, provides for better control of the supplying current, and reduces stress on the motor windings.

The required amperage is based on your model and options.  You should check your order confirmation details for the rated current draw required but as a general guide, these are the amperages required to start and operate your HOLTEC system:

Transcut II Series: 30AMPS (with Waste Conveyor): 40AMPS
HOLTEC V Series: 60AMPS includes Waste Conveyor and/or Power Inline Squeeze
HOLTEC Non-Integrated Package Aligner: 10AMPS

While our technicians may be capable of making the primary connection from the main fused disconnect to the system control panel, many jurisdictions require this connection to be performed by a certified electrician, therefore it’s important to have a certified electrician prepared to be on site for the connection in coordination with our on-site technician.

We hope to have served you with this information and ask you to please let us know if you need any further information on this, or any other preparatory matter
