NEC Requirements for Panelboards and Load Centers
The National Electrical Code (NEC) provides comprehensive safety standards for electrical installations, including requirements for electrical panels (main service panels and subpanels or breaker box).
Understanding Service Panels
Power from the utility company is typically delivered through three large conductors, which may enter the house overhead or underground. Overhead service wires are called a service drop. The drop runs to
