Question
Chapter 29, Problem 1R
To determine
State what minimum-size service is needed for a single family dwelling and also provide the NEC Code that states it.
Expert Solution & Answer
Answer to Problem 1R
The required minimum-size main service is 100 amperes and the Code is NEC 230.79(C).
Explanation of Solution
Discussion:
The National Electrical Code committee develops NEC – the standard electrical code. The main objective for the origin of the code is to protect and safeguard the person and elements from electrical hazards.
For a one family dwelling, according to National Electric Code NEC 230.79(C), the required minimum-size service is 100 amperes.
Conclusion:
Thus, the required minimum-size main service is 100 amperes and the Code is NEC 230.79(C).
