5/800A Generator Connection Point with Sequential Powerlocks

Generator Connection Point comprising of a wall mounting enclosure housing a set of single pole 800A drain powerlocks, which are sequentially interlocked, ensuring that the earth connection makes first and breaks last. The 800A drain powerlocks also mate with 500A source powerlocks allowing a common GCP to be used with either rating of connector.

Access to the powerlocks is controlled by a padlockable cover, which provides greater security against accidental or unauthorised withdrawal or insertion of connectors. A segregated termination chamber for the permanent mains outgoing connection is incorporated.

Enclosure
Wall mounting enclosure of seam welded construction, fabricated from mild steel, protected against corrosion by a high quality, outdoor finish comprising of a zinc phosphate pre-treatment followed by electrostatically applied and oven dried polyester powder paint, shade Dark Admiralty Grey (BS 4800 shade 18B25). For corrosive environments, enclosures can be fabricated from different grades of stainless steel (please specify at time of enquiry).
Enclosure dimensions: 965 x 668 x 248mm (H x W x D).

General arrangement
The upper outgoing termination chamber is protected to IP55 and houses a set of 5 no. 800A copper connection bars and has a removable rear access plate for the outgoing permanent cables. The bars are fitted with M12 stud terminals. The chamber is fitted with a top removable gland plate but this can be replaced by a projecting canopy.

The lower chamber is provided with a side hinged, padlockable door and is fitted with 5 no. 800A drain SP connectors (which are connected to the upper termination chamber). For additional safety, the powerlocks are sequentially interlocked, which require the earth to be mated first, followed by neutral, L1, L2 and L3. To disconnect the supply the sequence is reversed with the earth being removed last. Please note: single pole 800A connectors are compatible with 500A source connectors, allowing a common GCP to be used for all applications up to 800A.

The lower chamber has an open “letterbox” slot in the underside for cable entry. The door can be closed with 5 no. single core cables fitted with SP source connectors inserted into the drains.

Please note: the largest cable that can be terminated in a cable mounted single pole connector is 300mm².
