Another Happy Customer.
After we accessed our database from home we determined while on the phone with our customer which breaker would be used. North American Switchgear, Inc has an enormous database that is current and updated daily. This enabled us to provide the customer with accurate information.
After we spoke we hightailed into our facility to get the above breaker ready for service. LKD-8 circuit breakers are not a wipe down operate the mech and ship type of breaker. NAS puts all of our breakers through the whole gammit.
LKD-8 air circuit breakers are known for having possible mech issues and not surprisingly we performed some troubleshooting to get it ready for service. We not only meggered, ductored and primary injected the breaker, we also tested the anti-single phase device, the shunt trip, tested the fuses, the LS4 trip unit and perfomed other standard tests as well as cleaned the breaker. The LKD-8 mechanisms are very tricky but the expert breaker technicians at NAS know this is not their first rodeo. Our tech’s can run through these breakers like Jim Brown ran through defenses in the 1960’s.
