A lamp inside an enclosure provided for use during maintenance is an example of such a circuit. The control panel may be isolated but the lamp will require power so that the engineer can see while working on it.

Electricity is supplied to your home through your electric utility’s overhead or buried power lines. Before entering your home, electricity passes through a watt-hour meter which measures the amount of electricity used.

Soldered connections should be made only to terminals suitable for that purpose. Transformers may be fitted with turret tags suitable for soldering and printed circuit board assemblies may have solder pins.

Connections should be secured against accidental loosening. Correctly tighten terminal screws and where a connecting plug is fitted, use the clamps or screws provided to secure it to its mating socket.

The dedication of panels by power class is the most efficient measure to obtain an excellent “EMC” result. Moreover, separate routing of disturbing and sensitive cables ensures minimum coupling.

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...

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....

When your ignition switch is turned in the “start” and “run” position, the “I” or ignition terminal is energized and power flows from the battery through the primary winding of the ignition coil through the points and back to the engine ground. The primary winding of the ignition coil are...

A circuit is a closed loop of wiring and components beginning at the positive side of the battery and ending back at the negative side of the battery. This loop is often closed using a common ground. Electricity only flows when a circuit is a closed loop. If the loop...

Both line and wiring diagrams are a language of pictures. It is not difficult to learn the basic symbols. Once you do, you are able to read diagrams quickly, and can often understand a circuit at a glance. The more you work with both line and wiring diagrams, the better...
