Before entering your home, electricity passes through a watt-hour meter which measures the amount of electricity used.

Electrical equipment uses a wide variety of wire and cable types and it is up to us to be able to correctly identify and use the wires which have been specified. The wrong wire types will cause operational problems and could render the unit unsafe.

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 Claudie Ulysse. Electrical Wiring. Published at Saturday, January 20th 2018, 13:05:26 PM. Conductors and cables should run from terminal to terminal without any intervening joins. This refers to making a joint in the middle of a wire or cable. If it is necessary for any reason then use a suitable connector or terminal block. Don’t use a twisted and soldered joint.

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

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.

By Annette Noele. Electrical Wiring. Published at Saturday, January 20th 2018, 03:31:50 AM. 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.
By Sylviane Marcelline. Electrical Wiring. Published at Saturday, January 20th 2018, 02:36:35 AM. Where the circuits work at different voltages, the conductors must be separated by suitable barriers or all the wires insulated for the highest voltage to which any conductor may be subjected.
By Augustine Yvonne. Electrical Wiring. Published at Saturday, January 20th 2018, 01:45:37 AM. In general, contactors should be kept away from electronic devices. A highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.
