Understanding Tool Power
Power Formulas
- Watts = HP × 746
- Amps = Watts ÷ Volts
- Add 25% for startup surge
Circuit Requirements
- 15A circuit: Up to 1.5 HP @ 120V
- 20A circuit: Up to 2 HP @ 120V
- 240V: More efficient for 2+ HP
Safety
- Never exceed 80% of circuit capacity
- Use proper wire gauge
- Install appropriate breakers
- Consult electrician for 240V
Tips
- 240V more efficient for large tools
- Dedicated circuits for stationary tools
- Consider dust collector load
- Plan for future expansion
