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.
4
2. All grinders are wired 220 volts unless otherwise specied. Be sure motor specications (voltage, cycle, phase)
match power supply line. Be sure line voltage is up to specication.
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.
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.
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.
8. The size of the electrical wiring required from the power source to the mixer grinder with a 7½ HP grind
motor is a MINIMUM OF No. 10 WIRE. With 10 HP grind motor MINIMUM OF No. 8 WIRE to be used.
