110.12(B) Integrity of Electrical Equipment. Internal parts of electrical equipment must not be damaged or contaminated by foreign material, such as paint, plaster, cleaners, and so forth.
Electrical equipment containing damaged parts (broken, bent, or cut), or that has been deteriorated by corrosion, chemical action, or overheating, is not permitted to be installed.
Damaged parts include cracked insulators, arc shields (not in place), overheated fuse clips, and damaged/missing switch handles or circuit-breaker handles.

Grounding and Bonding Performance Requirements
Mike Holt, NEC Consultant

Electricity does not choose “the path of least resistance,” but flows on all paths presented to it. Though related and working together to form a protective system, grounding and bonding serve two completely different purposes. Two simplified definitions that are very important:

• Grounding is a connection to the earth.
• Bonding is a metallic, low-impedance path between metallic objects.

We connect electrical systems to the earth (ground) to limit induced voltage on the system windings and system conductors from indirect lightning strikes (those that are not a direct hit) [250.4(A)(1)].

For this to work, you must make the grounding electrode conductor and grounding electrode bonding jumpers no longer than necessary and avoid unnecessary bends and loops. Because it is both high-frequency and high-voltage, lightning can jump from those bends and loops to nearby objects instead of staying in the conductor. This jump is called a “side flash” and could cause a fire hazard if the side flash occurs around combustible materials (such as wood).

Metal parts of electrical equipment must be grounded (connected to the earth) to limit lightning-induced voltage to ground on the metal parts of equipment [250.4(A)(2)]. Where do you ground this equipment? The thing is, you don’t ground it directly. You bond it all to the equipment grounding conductor (EGC) and then you ground the EGC at services [250.24(A)], transformers [250.30(A)], and separate buildings supplied by a feeder [250.32(A)].

Do you know the purpose of an equipment grounding conductor? The intent of the equipment grounding conductor (EGC) is to provide an effective ground-fault current path back to the source of the electrical circuit to trip the overcurrent protective device and clear a fault fast.

This might surprise you, but there are fourteen permitted types of equipment grounding conductors listed in the NEC. Want to know what they are — and why they matter?

Learn all you need to know about the purpose of equipment grounding conductors and the different types of EGCs permitted by the Code by watching the video where Mike and the team help you to interpret the rules in section 250.118(A).
