What is the minimum size service for a one-family dwelling? ____________________

Expert Solution & Answer
Check Mark
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 100amperes.

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 100amperes, 3-wire.

Conclusion:

Thus, the minimum rating of service size for a one-family dwelling is 100amperes.

3. You have come to encounter an LTI system. You have no idea how the system behaves. So, you decide to drive the system with a particular input and measure the output. When you put the input u(t) = et 1(t), you find that the output y(t) = (1-e) 1(t). You can assume zero initial conditions. Now, find the transfer function of the system.
