The combined cross-sectional area of all conductors and cables is not permitted to exceed 50% of the interior cross-sectional area of the raceway. The fill provisions are based on the actual dimensions of the conductors or cables used.

In the case of a wire connection, it needs to be a very good conductor. Good conductors include most metals. The most common conductor used in wire is copper, although you may come across others such as aluminium. An insulator on the other hand is a material which does not allow an electric current to flow. Rubber and most plastics are insulators.

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.

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

When constructing junction boxes and pull boxes, you must be careful to exclude materials such as dust, flyings, oil and coolant. After you complete all wiring operations, you must seal all unused knockouts or openings.

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.

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.

That's 5,000,000 ohms! We know that a typical small engine ignition coil uses between 3 to 5 amps. By using the above mathematical formula we can determine that the bad spark plug ignition cable caused between 15,000,000 to 20,000,000 volts to be generated by the ignition coil!
