The focus on ensuring that all non-current-carrying metal parts are bonded together is crucial for preventing shock hazards. Bonding is a safety measure that involves connecting non-current-carrying metal components to create a low-resistance path for electrical current to flow safely to the ground. This is essential in an electrical system because it helps to mitigate the risk of electric shock by ensuring that, in the event of a fault, there is a controlled pathway for electricity, reducing the potential for voltage buildup on non-current-carrying surfaces.

The bonding of metal parts ensures that if any live conductor were to come into contact with these metal parts, the electrical current would travel through the bonding connections directly to ground, triggering protective devices such as circuit breakers or fuses. Therefore, this practice not only protects individuals from electric shock but also plays a critical role in maintaining the integrity of the electrical system overall.

The other options, while they may pertain to electrical safety or system integrity, do not directly address the specific requirement for bonding metal parts. Insulating current-carrying parts is important but does not relate to the bonding process. Verifying color coding is more about ensuring correct installation practices rather than shock hazard prevention, and confirming the length of conductors pertains to
