The maximum length of overhead service conductors permitted is how many feet?

• A. 5'
• B. 6'
• C. 7'
• D. 10'

Answer: (B)

The maximum length of overhead service conductors is restricted to ensure safety and functionality in electrical installations. According to the National Electrical Code (NEC), the maximum length permitted for overhead service conductors is 6 feet. This regulation is in place to reduce the potential for physical damage to the service entry, to minimize exposure to adverse weather conditions, and to effectively support the weight of the conductors. A length greater than 6 feet could lead to complications such as electrical hazards due to sagging, increased risk of mechanical stress, and difficulties in service maintenance. Therefore, the correct answer reflects an important safety measure in electrical design and installation practices.
