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. Safety of Personnel: By safely channeling fault currents into the ground, proper grounding helps to reduce the risk of electric shock to personnel. Grounding is covered in greater detail in HSB's Recommended Practices for Grounding of Commercial.

The Basics of Grounding and Bonding

For grounded systems, the NEC requires you to perform all of the following: electrical system grounding, electrical equipment grounding, electrical equipment bonding,

DISTRIBUTION BOX

Each DISTRIBUTION BOX and controller must be grounded. On the US market, a 5.26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used.

System Grounding

For solidly-grounded systems, an unspliced system bonding jumper must be used to connect the equipment grounding conductor of a separately derived system to the grounded conductor.

System Grounding

Because parts of the power system, such as equipment frames, are grounded, and the rest of the environment essentially is at ground potential also, this has big implications for the system.

The Basics of Grounding and Bonding

By definition, as well as by function, grounding and bonding are not the same thing. However, they do work closely together in a yin-and-yang relationship to help
