The definition of service entrance.
Explanation of Solution
The service entrance is one of the most crucial components of a residential electrical system. The service entrance gives the home's electrical system access to the electric utility company's power supply.
The service conductors at an underground service entrance run from the service main disconnect terminals to the point where the underground utility wire is connected.
Several of the requirements for the installation of service entrances are covered by Article 230 of the NEC®. The specifications for grounding a residential service entrance are covered by Article 250 of the NEC®.
The local electric utility must be approached after the kind of service entrance being placed is selected, and the service type, location, and installation must all be planned with them.
Conclusion:
The service entrance gives the home's electrical system access to the electric utility company's power supply.
