6.a. The amount of short-circuit current that flows depends upon the amperes available at the source of power, the length of the circuit, and what other primary factor? A. The presence of a ground fault current B. Proper installation of the branch circuit C. Presence of no previous damage to the electrical system D. The size of the conductors and voltage at which they operate 6.b. You're evaluating the components of a multioccupancy building that won't have an on-site employee. To be compliant with the NEC, each occupant will need to have access to their own A. service-disconnecting means. B. service conductor. C. cable attachment point. D. emergency fire water-pump disconnect.
Protection System
A system that protects electrical systems from faults by isolating the problematic part from the remainder of the system, preventing power from being cut from healthy elements, improving system dependability and efficiency is the protection system. Protection devices are the equipment that are utilized to implement the protection system.
Predictive Maintenance System
Predictive maintenance technologies are designed to assist in determining the state of in-service equipment so that maintenance can be scheduled. Predictive maintenance is the application of information; proactive maintenance approaches examine the condition of equipment and anticipate when it should maintain. The purpose of predictive maintenance is to forecast when equipment will fail (depending on a variety of parameters), then prevent the failure through routine and corrective maintenance.Condition monitoring is the continual monitoring of machines during process conditions to maintain optimal machine use, which is necessary for predictive maintenance. There are three types of condition monitoring: online, periodic, and remote. Finally, remote condition monitoring allows the equipment observed from a small place and data supplied for analysis.
Preventive Maintenance System
To maintain the equipment and materials on a regular basis in order to maintain those running conditions and reduce unnecessary shutdowns due to unexpected equipment failure is called Preventive Maintenance (PM).
