This online engineering PDH course provides general requirements, classifications, installation, maintenance, testing, and application information for circuit control devices, and covers the requirements for switches, relays and solenoids.
Circuit control in its simplest form, is the application and removal of power. This can also be expressed as turning a circuit on and off or opening and closing a circuit. Before you learn about the application of circuit control devices, you should know why circuit control is needed. If a circuit develops problems that could damage the equipment or endanger personnel, it should be possible to remove the power from that circuit. The circuit protection devices (fuses and breakers) are not the control devices; these are protection devices that will remove power automatically in event of overload conditions. Circuit control devices allow you to turn the device ON when it is needed and OFF when it is not needed.

This online engineering PDH course describes how a proper circuit protection strategy reduces long-term maintenance needs and costs, and minimizes system downtime.
Too much current flowing through an electric circuit can damage the circuit and can create a safety hazard. How much current is "too much current"? That depends on the circuit and its components. For some circuits, 1 ampere would be too much current, while for other circuits 1 ampere would be perfectly acceptable. A proper circuit protection strategy reduces long-term maintenance needs and other costs, and minimizes system downtime. Circuit protection devices protect electrical equipment by rapidly disconnecting power to components in the event of an abnormal overload conditions resulting from excessive voltages, ground faults, and accidental shorting of a circuit.

This online engineering PDH course provides general requirements, classifications and application information for electrical conductors.
A conductor is a piece of metal used to conduct electricity, known colloquially as an electrical wire. Wires are very good conductors, which mean that they have very little resistance. In fact, their resistance is so small that often we consider it to be zero. (In other words, we often treat wires as perfect conductors).
In United States, conductors are measured by American wire gauge (abbreviated AWG) for smaller ones, and circular mils for larger ones. To give you some idea how thick these wires are; AWG 0000 wire is about 11.7 millimeters in diameter (a little less than one-half inch thick) and at the opposite end of the scale, AWG 40 is less than 0.1 millimeters in diameter (about as thick as a strand of hair from your head). The wiring inside the walls of your home is usually AWG 10 or AWG 12 wire.
This 2 PDH online course is applicable to students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers who are interested in gaining a better understanding of electrical conductors.

This online engineerng PDH course explains how transformers convert between high and low voltages, change impedance, and provide electrical isolation between circuits.
A transformer is an electrical device that transfers energy from one circuit to another purely by magnetic coupling. Transformers are often used to convert between high and low voltages, to change impedance, and to provide electrical isolation between circuits.
A basic transformer consists of two sets of coils or windings close to each other (sometimes wrapped around an iron or ferrite "core"). Each set of windings is simply an inductor. Power is fed into one coil (the "primary"), which creates a magnetic field. The magnetic field causes current to flow in the other coil (the "secondary"). The alternating current that flows through the primary winding establishes a time-varying magnetic flux, some of which links to the secondary winding and induces a voltage across it. The number of times the wires are wrapped around the core ("turns") is very important and determines how the transformer changes the voltage.
This 4 PDH online course is applicable to electrical engineers, design and construction personnel, technical staff and facility personnel who are interested in gaining a better understanding of transformers.
