Where would you expect to find outside branch circuits and feeders?

The correct answer indicates that outside branch circuits and feeders are typically found running on or between buildings or located on or attached to poles. This is consistent with the National Electrical Code (NEC) requirements, which stipulate that outdoor circuits should be installed in a manner that protects them from physical damage and environmental factors.

Outside branch circuits and feeders are designed to provide electricity to outdoor equipment, lighting, or other exterior installations, and they need to be installed where they can be safely accessed and maintained. This means using proper equipment, such as overhead conductors on poles or underground feeders protected with appropriate conduits when needed. The design ensures that they meet safety standards, reducing risks of electrical hazards or outages.

Other options suggest placements that do not align with standard practices for outside branch circuits. For instance, placing circuits inside a building's main service panel would mean they're not readily accessible for outdoor applications. Similarly, burying them underground without any protection contradicts safety measures because unprotected underground wiring can be vulnerable to moisture, physical damage, or other environmental factors. Placing circuits within the walls of a structure pertains more to indoor wiring and does not accommodate the specific needs of exterior circuits.
