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

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.

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.

To measure AC voltage for example on your engine’s stator, you first locate the two wires coming from the stator. Turn your DMM to AC Voltage. Place the red probe onto one of the wires, and the black probe on the other wire. You should read about 24 to 30 VAC.

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.

The control panel may be isolated but the lamp will require power so that the engineer can see while working on it.

Modern electrical machine tool equipment may vary from that of a single-motor machine (such as a drill press that performs simple, repetitive operations) to very large, multimotored automatic machines, which contain highly complex electrical control systems. Typically, these machines are especially designed, factory-wired, tested by the builder and then erected in the plant.
