What does the term 'service drop' refer to in electrical installations?

The term 'service drop' specifically refers to the overhead or underground electrical wires that deliver electricity from the utility company's power lines directly to a residential or commercial building. This is a crucial component of electrical installations, as it is the means by which electrical power is supplied to a structure.

The service drop typically includes the conductors that connect the power source to the building's service entrance, where the electrical system begins. This connection is vital for ensuring that electricity is properly routed to the interior circuits of the building for use in lighting, outlets, and appliances. Understanding this term is fundamental for anyone working in electrical installations, as it relates directly to the safety, reliability, and efficiency of the electrical supply.

Knowing what a service drop entails helps in recognizing the importance of proper installation and maintenance, as well as compliance with safety regulations.
