Grounded conductors that are how many AWG have a continuous white or gray outer finish?

In electrical wiring, grounded conductors are integral for ensuring safety and preventing electrical hazards. The National Electrical Code (NEC) stipulates that grounded conductors must have a specific color coding to eliminate confusion and ensure they are easily identifiable. For conductors sized 6 AWG and larger, a continuous outer finish must be either white or gray. This color standard helps electricians and technicians quickly recognize which conductors are intended to be grounded, thereby promoting safe practices in electrical installations.

This specification is crucial for the safety of electrical systems, as improperly identifying a grounded conductor can lead to serious accidents or electrocution. Smaller sizes, like 2, 4, and 10 AWG, do not fall under the same requirement for a continuous white or gray finish, which is why they are not applicable in this context. Therefore, recognizing that 6 AWG is the size that mandates this specific color coding for grounded conductors underscores its correct identification in the practice of electrical work.
