Question
Chapter 22, Problem 1RQ
To determine
The advantage of the point-to-point method of connecting circuit components.
Expert Solution & Answer
Explanation of Solution
The point-to-point connection method is a method used for the installation of components in a control circuit. The wires in the control circuit are given a wire number, but not for the wires in the load circuit. Dashed lines are used to represent the components located in MCC (motor control center). The components are connected from one point to another based on the proximity of the components.
The advantages of the point-to-point method of connecting components are as follows:
- Saves the mount of wire required by reducing the wastage of wire.
- The connections inside and outside the motor control center can be distinguished.
- The wire tags and the real terminal designations are shown.
- It is easy to troubleshoot and service.
- It is easy to identify the components.
