MOTOR WIRING AND ELECTRICAL REQUIREMENTS
(1) Interchange of current is made in motor outlet box. Leads are properly marked. Changing instructions are on
the motor plate or motor outlet box.
(2) All chippers are wired 220 volts unless otherwise specified. Be sure motor specifications (voltage, cycle, phase)
match power supply line. Be sure line voltage is up to specification.
(3) Electrical connections to be in accordance with safety codes and National Electrical Code.
(4) Rated voltage of the unit shall be identical with full supply voltage.
(5) Voltage drop on the supply line shall not exceed 10% of full supply voltage.
(6) The feederline conductor size in the raceway from the branch circuit to the unit must be correct to assure
adequate voltage under heavy starting and short overload conditions.
(7) The feederline conductor shall only be used for the supply of one unit of the relevant horsepower. For
connections of more than one unit on the same feederline, a local electrician will have to be consulted to
determine the proper conductor size.
(8) The size of the electrical wiring required from the power source to the frozen block chipper is a MINIMUM OF
No. 10 WIRE if the distance from the machine to electrical box is 25 feet or less. Over 25 feet a MINIMUM OF
No. 8 WIRE is to be used.
(9) The BIRO Manufacturing Company is not responsible for permanent wiring, connection or installation.
