'<br>Busbar (double or duplicated) bus system is usually placed between the two wires of the outdoor power supply. This system is known as single-ended bus bar or double-ended busbar. This system usually consists of two busbars, an outer busbar having the ability to carry the current to the outdoor power connection and an interstage busbar having the ability to carry the power from the outside to the inside of the garage. Each busbar also has the ability to carry the entire substation load to the garage.<br><br><br>Busbars are usually protected by a high rating thermal breaker, insulated metallic housing and by an overload resistant rating of at least 600 volts per busbar. Busbars are often protected by both an overload and thermal breakers. Some manufacturers provide protection against electromagnetic interference as well.<br><br><br>Duplicate busbar system consists of an outer busbar having the ability to carry the current to the power connection, and an interstage busbar having the ability to carry the power to the garage. In this arrangement, each of the busbars serves the dual purpose of supplying the load with electrical energy and transmitting the same to the outside. The interstage busbar arrangement is usually suitable for multiple outlets. This system requires a separate connection for each single outlet.<br><br><br>Busbar wiring can be installed in different ways depending on the function of the system and the required size and spacing of the busbars. It can be installed as a complete wiring system with multiple installation areas, by using a standard electrical box and cover, or by using several panels of busbar wiring arranged in series or parallel. Both ways offer flexibility for different applications. For a small system such as a garage it is possible to install the complete wiring system in a single installation area. However, if the space is large enough, it is usually better to use several panels to spread the weight of the wiring to a larger extent and make the system more efficient.<br><br><br>An example of such a system is the 'double-sided' tandem feeder contacts. The tandem frame consists of two circular busbars and two earthing spouts. The tandem frame provides for easy attachment of earthing plates to the flat bottom of the busbars.<br><br><br>Another example of busbar system that uses a double circuit arrangement is the 'single-sided' feeder contacts. This arrangement allows only one earthing plate to be supported at a time. The system is called upon to handle one heavy circuit when the entire load on the system is placed upon it.<br><br><br>Duplicate busbar arrangements are also very commonly found in high voltage power supplies. The most obvious application is in the system failure of the primary power supply to the breaker box. If the switch fails to trip the circuit breakers, the supply rail is left ungrounded causing a short in the power flow to the breaker box. In this case, the wiring system will still allow current to travel between the panel contacts, however, the chances of short circuits developing are greatly increased.

Thus, the same principles apply in that the potential for a short circuiting current is greatly increased with duplicate busbar arrangements.<br><br><br>One can also find these same faults in many industrial appliances that are controlled by relay systems such as machinery control panels, panel board testers, etc. Some manufacturers make their equipment susceptible to tripping due to the presence of stray switching contacts in a particular wire pair. When one of the contacts shorts out, the circuit breaker will trip the relay. Because the equipment must be shut down immediately, this will frequently not allow time for the circuit to be repaired in order to prevent a trip. Because of this, the equipment will continue to run and potentially trip more components, which will cause an even higher level of failure if the equipment is operating under power load. This can be especially dangerous in the event of an emergency when the equipment may stop working altogether, leaving critical personnel trapped inside.<br>'
