Frequently Asked Questions
Sum nameplate ratings of all equipment, apply diversity factor (0.7-0.8), add 25% safety margin. Include lighting (3W/sq ft), outlets (180VA each), and HVAC loads. Use NEC Article 220 for commercial calculations.
Motor circuits: 125% of full load current. General outlets: 20A typical. Dedicated equipment: nameplate current × 1.25. Always consult NEC Table 430.52 for motor protection and local codes for specific requirements.
Use high-efficiency motors, LED lighting, power factor correction, load scheduling during off-peak hours, variable frequency drives for large motors, and regular maintenance to optimize equipment efficiency.
Power factor is ratio of real power to apparent power. Poor power factor (<0.85) increases utility costs and reduces system capacity. Motors and fluorescent lights cause low power factor. Capacitors can improve it.
Calculate current load, add planned equipment, include 25% spare capacity. Typical hobby shop: 100A panel. Small commercial: 200A. Large shops: 400A+. Consider 3-phase for motors >5HP.
GFCI protection for outlets, proper grounding, adequate lighting, emergency shutoffs, arc-fault protection, regular inspections, proper wire sizing, and compliance with NEC Article 210 for branch circuits.
