Electrical Installations

Electrical installation is the process of installing wires or cables and related devices in a building structure. Along with electrical wires, an electrical installation includes installing equipment such as switches, distribution boards, lights, electrical panels, and other components. The electrical installation is carried out by an electrician. An electrician is a trained individual who is specialized in electrical-related works and provides electrical services. When it comes to electrical installations, the electrical code specifies the right wire to be used for installations, this will ensure safety and prevent future fire hazards resulting from short-circuiting and overvoltage.

Question

What is the sequence of the operations if the limit switches, shown in Figure 5– 6, are used. What will happen in Figure 5–6 if limit switches are installed and the jumpers from terminals 6 and 7 to the coils are not removed?
