28 (Box Materials): Metal boxes (like your cabinet) must be reliably grounded and bonded, period. 26 (Clearance Requirements): Ensures workers can safely access equipment doors without obstructions—no cramming wires around hinges!NEC 314. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. This ensures safety by reducing the risk of electric shock and ensuring proper grounding in hazardous situations. Circuits are grounded to limit excessive voltage from lightning, transient surges, and unintentional contact with higher voltage lines, and to limit the voltage to ground during normal operation.
