What is the purpose of underground burial requirements for residential branch circuits?

Safety from physical damage
Protection from voltage fluctuations
Improving signal quality
Cost reduction

The correct answer is: Safety from physical damage

The purpose of underground burial requirements for residential branch circuits primarily focuses on safety from physical damage. When electrical conductors are buried underground, they are less susceptible to physical impacts that can occur from outdoor activities or environmental conditions, such as severe weather or construction activities. This requirement is established to minimize the risk of accidental damage to electrical wires, which could lead to shorts, fires, or electric shock hazards. By placing the circuits underground, electricians can ensure the integrity of the wiring system, thus enhancing the overall safety of the electrical installation in residential areas. This reflects a fundamental principle in electrical work: prioritizing safety while minimizing risks associated with exposed wiring. The other options do not directly address the primary concern of protecting electrical infrastructure from external threats.
