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.

You must totally enclose conductors and their connection external to the control panel enclosure in suitable raceways or enclosures. Unless used for flexible connections involving small or infrequent movements, or connections to normally stationary motors, limit switches and other externally mounted devices, fittings used with raceways or multiconductor cables must be liquidtight.

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 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.

Dashed lines are drawn between the symbols to denote which switches control specific lights or receptacles. 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!

No click of the solenoid, nothing happens at all. Before assuming your starter is bad, grab your DMM and set it to DC Volts. Remove the wire going to the small terminal of your starter solenoid and connect the red probe of your DMM to the wire. Now connect your black probe to a ground. Turn your tractor’s key. Your DMM reads no voltage. This tells you that power is not going from your battery to the solenoid. Next remove the wires from the back of your ignition switch that are connected to the “B” and “S” terminals on your switch. Set your DMM to Continuity and connect your probes to the “B” and “S” terminals of the switch. Turn your tractor’s key and if there is no “beep” you know your ignition switch has a short internally and should be replaced.

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