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

If the screen is to be connected then make it off in the same way as for coaxial cable with a soldered pigtail and a sleeve.

This is essential for industrial control systems that may contain hundreds or thousands of wires. These numbering schemes are often particular to each facility, but there are tools to help make wire labels that will appear in the final controls cabinet.

Ensure that identification tags and cable markers are legible, marked with a permanent ink and suitable for the environment where the panel is to be used. They should also correspond with those shown in the machine drawings and instruction or service documentation.

From an electrical standpoint, industrial machine equipment and tools - from drill presses to multi-motored automatic machines - can present special fire and shock hazards.
By Augustine Yvonne. Electrical Wiring. Published at Wednesday, August 30th 2017, 02:31:22 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

Published at Monday, August 28th 2017, 02:21:14 AM. • Black represents ungrounded line, load and control conductors at line voltage. • Red represents ungrounded AC control conductors, at less than line voltage. • Blue represents ungrounded DC control conductors. • Yellow represents ungrounded control circuit conductors that may remain energized when the main disconnecting means is in the OFF position. These conductors must be yellow throughout the entire circuit, including wiring in the control panel and the external field wiring. • White or natural gray represents a grounded circuit conductor. • White with blue stripe represents a grounded DC current-carrying circuit conductor. International and European standards require you to use light blue for the neutral conductor. • White with yellow stripe represents grounded AC current-carrying control circuit conductors that remain energized when the disconnecting means is in the OFF position. For additional circuits powered from different sources that remain energized when the main disconnecting means is in the OFF position, you must use striping colors other than green, yellow or blue to uniquely identify the grounded conductors.
By Annette Noele. Electrical Wiring. Published at Tuesday, August 22nd 2017, 02:08:06 AM. You are required to use pressure connectors to connect conductors to devices with lug-type terminals that are not equipped with saddle straps or equivalent means of retaining conductor strands.
By Augustine Yvonne. Electrical Wiring. Published at Sunday, August 20th 2017, 01:27:26 AM. It is uncommon for engineers to build their own PLC panel designs (but not impossible of course). For example, once the electrical designs are complete, they must be built by an electrician. Therefore, it is your responsibility to effectively communicate your design intentions to the electricians through drawings.
By Augustine Yvonne. Electrical Wiring. Published at Friday, August 18th 2017, 23:53:53 PM. For grounded control circuits, you may use a green (with or without one or more yellow stripes) or a bare conductor to connect the transformer terminal to a grounding terminal on the control panel.
