Grounding Distribution Boxes: Where Theory Meets Sweaty Palms The Dirty Secrets of "Quick Fix" Installations Picture this scene: An electrician rushes through a distribution box
Article 250 of the NEC covers the grounding and bonding of electrical systems. By definition, as well as by function, grounding and bonding are not the same thing.
An electrical distribution box is a centralized unit responsible for distributing electrical power across multiple circuits within various
Good system grounding provides the path for normal load and fault currents while maintaining load and controls temporary overvoltages. Good equipment grounding ensures personnel safety.
Technicians often have an “Anything Goes; It''s Temporary” attitude about grounding, bonding, when dealing with the installation of temporary
