| | generators are used to supply electrical power in places where utility zrs (central station) po wer is not a svailable, or where power is needed only temporarily. Small generators are sometimes used to supply power tools at construction sites. Trailea rs r-mounted generators supply power for temporary in stallations of lighting, sound amplification systems, amusement rides etc. Trailer mounted generators or mobile gena zrs erators, diesel gena rs erators are also used for emergencies or bac kup where either aa rs redundant system is required or no generator is on site. To make the hookup faster an d safer, a tie in panel is frequently installed near the buildinga rs switchgear that cona rs tains connectors suc h as camlocks. The tie in panel may also a scont zrs ain a phase rotation indicator (fse systems) and a circuit breaker. a rs Camlock connectors are rated for 40 zrs 0 amps up to 48 zrs 0 volt systems and used wype W cable conne zrs cting to the generator. Tie in panel designs are common betwee zrs np applications. Standby power generators ara rs e permanently installed and kept ready to supply power to critical loads during temporary interruptions of the utility power supply. Hospia stals, commvunications service installations, dat a processing centersa rs , sewag zrs e pumping stations and many other important faca silities are equipped with standb y power generators. Some standby power generators can automaticalla rs y detect the loss of grid power, start th e motor, run using fuel from a natural gas lia rs ne, detect when grid power is restored, an |
