Example text

3 Condition of Control During and After Test. The control shall not close the recloser from an open position during the application of surges. Tripping from a closed position is permissible on a reclosing switchgear device. Malfunction of the control t o cause lockout on one surge is not permissible. Following the tests, the recloser and control apparatus shall be capable of performing all normal functions without impairment. 2 Control, Secondary Wiring and Accessory Devices Check Tests. Control, secondary wiring and accessory devices shall be checked to ensure that all connections have been made correctly.

A recloser shall be provided with a position indicator, or other suitable means, which clearly indicates its closed, or open position and shall be visible from the surface. For pad mounted, dry vault or submersible reclosers viewing of the position indicator may require opening of the enclosure. If colors are used to indicate an open or closed position, red shall signify closed and green signify open, with the words OPEN or CLOSED in contrasting colors. 2 Grounding Provisions. A recloser with a metal housing shall have provisions for the connection of a ground lead.

A recloser with a metal housing shall have provisions for the connection of a ground lead. The ground connector shall accommodate a ground conductor of a size adequate to conduct the rated interrupting current of the recloser for a period of 3 s without damage t o the conductor or connector. Pad mounted, dry vault and submersible reclosers shall have an additional grounding connection for each three-phase set of cable entrances. 7 Nameplate Markings. The following minimum information shall be given on the nameplate : (1)Manufacturer’s name or trademark (2) Manufacturer’s type or identification number to indicate the design or construction.
