Purpose of this method statement is to define the sequence of GCB generator circuit breaker installation and safe execution of the job. Procedure applies for GCB transportation, handling, and installation at electrical building / roof where these activities will be performed as per the project requirements.
When the charging mechanism is actuated by hand with a hand crank or by a motor (50.4), the flange (50.3) turns until the driver (50.3.1) locates in the cutaway part of the cam disc (62.3), thus causing the charging shaft to follow. The crank (62.2) charges the closing spring (62.0). 22 GMSG and GMSG-GCB vacuum circuit breakers | Instruction manual
While the type GMSG-GCB generator circuit breaker is capable of rapid reclosing duty, fast reclosing should never be used in a generator circuit to avoid major damage to the generator. Manual operation Electrically-operated vacuum circuit breakers can be operated manually if the control supply should fail.
GCB will be transported from lay down area to site with crane. GCB will be fixed safely in the crane board. At the working area, GCB will be placed in a way that will not prevent safe access and egress. The assembly drawings will be checked on the place of installation. Support of GCB will be installed on the roof.
