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).
