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.

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.

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

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

From an electrical standpoint, industrial machine equipment and tools - from drill presses to multi-motored automatic machines - can present special fire and shock hazards.

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.

I want to emphasize that the wear is very slight, and cannot replace an actual valve seat cutter. I use valve lapping compound to show me the contact points from the valve seat onto the valve face.

There are quite a few symbols used to represent the devices used in home electrical wiring but some of them are very similar, so care should be used when working with them!
