From an electrical standpoint, industrial machine equipment and tools - from drill presses to multi-motored automatic machines.
By Annette Noele. Electrical Wiring. Publised at Thursday, January 18th 2018, 23:29:05 PM. Modern electrical machine tool equipment may vary from that of a single-motor machine (such as a drill press that performs simple, repetitive operations) to very large, multimotored automatic machines, which contain highly complex electrical control systems. Typically, these machines are especially designed, factory-wired, tested by the builder and then erected in the plant.

Line diagrams, also called “schematic” or “elementary” diagrams, show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller. They are an ideal means for troubleshooting a circuit.

When electricity was originally used for practical purposes, it was used for communication in the form of the electric telegraph and the telephone. Petroleum and paraffin lamps were still lighting homes until the late 1800s, when Thomas Edison developed the light bulb.

You're permitted to use wiring channels if they're made of a flame-retardant insulating material. If you're working with back-connected control panels, you must provide access doors or swing out panels that swing about a vertical axis. Multiple-device control panels must have terminal blocks or attachment plugs and receptacles to terminate and connect all outgoing control conductors.

Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.

However, an exception allows you to install a splice in leads attached to electrical equipment, such as motors and solenoids.

By Babette Benjamine. Electrical Wiring. Published at Friday, February 02nd 2018, 06:55:41 AM. When the current is switched on or off, the electro-magnetic field increases and decreases, rapidly causing, in effect, a radio signal. The effect is similar to the crackle that can sometimes be heard on the radio or television when something like a fridge switches on and off. This radiated signal can be picked up by the other wires in the system and cause interference to the normal working voltages in the system
