Electric Pipe Installation In electrical engineering installation, installation cable and the installation of lighting energy must be free from various kinds of interference from outside (Eg : impact, pulling, scratching). Thus pipe installation must meet the requirements set by the installation of the authorities Teknologi dan Rekayasa

Fuse When a circuit uses too much electricity, an overcurrent causes a circuit breaker to trip, shutting down the power to that circuit. The excessive heat caused by an overcurrent condition may burn or damage a conductor’s insulation and cause a fire. A circuit breaker is a heat-sensitive switch, which automatically trips when electricity demand is too great which causes the temperature in the conductor to get too hot. Teknologi dan Rekayasa

Cable Types (cont.) In cable, there are four different colors or kinds of wire that one will use depending on the type of wire that is being used. Using 12-gauge wire as the example, there are four types of cable that one may buy. Teknologi dan Rekayasa

Cable Types (cont.) One is 12/2 with ground, which has one black conductor, one white conductor, and a bare ground conductor. A second cable is 12/2 without ground, which is the same as 12/2 with ground except that no bare ground conductor exists. Teknologi dan Rekayasa

Cable Types (cont.) A third type of cable is 12/3 with ground, which has one black conductor, one white conductor, one red conductor, and one bare ground conductor. The last type is 12/3 without ground which is like the 12/2 without ground. It has the three colored conductors, but no bare conductor. Teknologi dan Rekayasa

Diagramming Generally, black and red conductors carry “hot” power or current from the source to the devices within the circuit. The white conductor is always used to carry the current back to the source. Teknologi dan Rekayasa

Diagramming (cont.) When completing the diagram, it may be helpful to draw the white, neutral conductor from the source to its final destination within the circuit, first. Duplex receptacles and pull-chain lamp holders are normally wired so that they have “hot” or un-switched power at all times. Teknologi dan Rekayasa

Diagramming-3 way switches 3-way switches are always used in pairs. They are needed when one wishes to control a light from two different locations. Teknologi dan Rekayasa

Diagramming-3 way switches (cont.) 3-way switches have three screws or terminals, one is called control or common terminal. It is often darker colored than the other two terminals. The other two terminals are called traveler terminals. Teknologi dan Rekayasa

Diagramming-3 way switches (cont.) When the toggle switch is in one position, the common terminal carries current to one traveler terminal. When the toggle switch is in the other position, the common terminal carries current to the other traveler terminal. Teknologi dan Rekayasa

Diagramming-3 way switches (cont.) When diagramming and wiring 3-way switches, the hot current always enters the control terminal of one of the switches and always exits out of the control terminal of the other switch. The traveler terminals from one of the switches must connect to the traveler terminals of the other switch with no interference. Teknologi dan Rekayasa
