Electrical Standard for Industrial Machinery, helps you ensure fire safety by addressing the electrical considerations specific to equipment, apparatus, and systems used in industrial manufacturing processes.

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.

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.

However, an exception allows you to install a splice in leads attached to electrical equipment, such as motors and solenoids.
By Claudie Ulysse. Engine Wiring. Published at Sunday, September 17th 2017, 09:47:23 AM. A circuit is a closed loop of wiring and components beginning at the positive side of the battery and ending back at the negative side of the battery. This loop is often closed using a common ground. Electricity only flows when a circuit is a closed loop. If the loop is open no electricity flows.

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 Charline Rodrigue. Electrical Wiring. Published at Wednesday, September 13th 2017, 08:59:20 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

By Annette Noele. Electrical Wiring. Published at Saturday, September 09th 2017, 08:05:01 AM. Electricity is supplied to your home through your electric utility’s overhead or buried power lines. Before entering your home, electricity passes through a watt-hour meter which measures the amount of electricity used.
