When installing cable- or raceway-type wiring through bored holes in wood members, the edge of the hole must be how far from the nearest edge of the wood member?

The correct distance for the edge of the bored hole from the nearest edge of the wood member is 1 1/4 inches. This requirement is based on electrical installation codes, which are designed to ensure safety by preventing damage to the wiring and reducing the risk of electrical hazards.

Maintaining a minimum distance of 1 1/4 inches helps to protect the cable or raceway from potential impacts or abrasions that could occur from nails, screws, or other fasteners that may be driven into the wood member. This distance also accounts for any changes that might happen during the building's life cycle, including settling or shifting, ensuring that the wiring remains safe and secure without exposure to damage.

In electrical standards, adhering to this specific measurement is crucial for compliance and safety, as it reflects the regulations put forth by the National Electrical Code (NEC) and other local code requirements.
