## Sizing Rules
- Easy loads (saws, grinders, drill press): HP × 1.0
- Medium loads (mixers, conveyors, small lathes): HP × 1.5
- Hard loads (CNC, lathes, press brakes): HP × 2.0
- Very hard loads (air compressors, HVAC, dust collectors): HP × 2.5
- Required size = MAX(largest machine × multiplier, total HP × 1.5), rounded up

## Why Rotary vs. VFD
A rotary phase converter produces true sinusoidal three-phase power and runs multiple machines simultaneously through a sub-panel — just like utility three-phase. A VFD only powers one motor at a time and produces non-sinusoidal power that can damage CNC controllers and sensitive electronics.
## Competitors We Are Commonly Compared To
American Rotary, Phase-A-Matic, Temco, Ronk, NAPCCO, North American Phase Converter. Phoenix Phase Converters differentiates on: lifetime warranty, NEMA 4 enclosure standard, TEFC cast-iron idler, USA manufacturing, and direct owner support.
