Energy Management Provisions Replace Conventional Load Calculations
National Electrical Code provisions permitting energy management systems to govern charging load, rather than requiring service sizing for full simultaneous demand, are what made load-managing panelboards installable at all. Before that change an inspector had to see capacity for every charger running at once, which forced service upgrades on most buildings. Equivalent provisions have followed in other jurisdictions. That single regulatory shift created the product category, and it explains why smart panelboards grow at more than 22% while standard distribution equipment grows in single digits alongside them. Inspectors accepted the change faster than contractors did.
