What is the maximum distance allowed for the electrical service entrance to the meter?

• A. 5 feet
• B. 10 feet
• C. 15 feet
• D. 20 feet

Answer: (B)

The maximum distance allowed for the electrical service entrance to the meter is specified to ensure that the installation adheres to safety standards and operational efficiency. This distance is typically set at 10 feet to avoid excessive voltage drop and to ensure that the service can adequately supply the necessary power to the premises without significant loss of energy along the way. When the distance between the service entrance and the meter is too long, it can introduce resistance, potentially leading to lower voltage at the load and increased heating in the wiring. This can create safety hazards and affect the performance and lifespan of electrical appliances and systems. Therefore, limiting this distance helps to maintain effective electrical service while minimizing risks associated with longer cable runs. Standards and codes, such as those set forth by the National Electrical Code (NEC), provide guidelines that professionals must follow to ensure safety and compliance in residential electrical installations.
