Chapter 28, Problem 1R
What is the minimum size service for a one-family dwelling? ____________________
Expert Solution & Answer
To determine
Find the minimum rating of service size for a one-family dwelling.
Answer to Problem 1R
The minimum rating of service size for a one-family dwelling is
Explanation of Solution
Discussion:
The National Electrical Code committee develops NEC – the standard electrical code, and the main objective for the origin of the code is to protect and safeguard people and elements from electrical hazards. The codes that explain the rating of service disconnecting means are defined in an article NEC 230.79.
According to an article NEC 230.79 (C), for a one-family dwelling, the rating of the service disconnecting means should not be less than
Conclusion:
Thus, the minimum rating of service size for a one-family dwelling is
