GFY recommends 600v 12 ga stranded wire for all 1 phase GFY installations.
•
Size of input and output wires may go up based on length and current draw of VFD and motor.
•
See Power Requirements (page after next) for current draw of VFD and motor.
VFD = Variable Frequency Drive
A separate insulated ground must be provided to each
VFD from the electrical panel.
Motor is rated with an Insulation Class H or F;
Ensure proper wiring is used as per current electrical codes.
