Spring pressure

GM250T5, GM250T5N, GM250T5G, GM250T5NG Systems Track Busway housing sections consist of an extruded Aluminium shell with “spring-pressure” type copper channel busbars contained in a full length halogen-free insulator mounted on the interior walls. The Aluminium extrusion acts as a 100% protective earth meeting IEC 60439-2. Each housing has a continuous access slot over its entire length for the insertion of turn-n-lock plug-in units. The plug-in opening features finger safety to IP2X. Housing configurations include 3 or 4-pole varieties 220…415V, optional isolated protective earth, and optional oversize (200%) neutral. The housing sections join together using Bus Connectors which fit into the channels of the adjoining section. An Installation Tool is used to force the blades into the busbar channels for a solid “spring-pressure” electrical connection.

END POWER FEED UNITS


End Power Feed Units Standard End Power Feed units connect to the end of any busway section. Factory assembled unit consists of a 305 X 406 X 165mm steel junction box with removable sides connected to a 305mm section of busway. The assembly includes connection lugs for wires up to 152mm2. Chassis earth isolated earth allow wires up to 67mm2 and 42mm2 respectively. Reverse End feed units for connection to opposite end of busway section (polarizing stripe faces to right as viewed from junction box end of unit). End Power Feed units are connected to adjacent Busway sections using Housing Coupler and Bus Connector which are sold separately. (Joint Kit – T5 Series) Special need Power Feed units for confined spaces as might be found in Mission Critical Data Centers can also be designed and fabricated, requiring minimum quantities. Reference page 5.1b for dedicated ground application. Contact UEC representative for further information.

JOINT KIT/INSTALLATION TOOL

GM250T5, GM250T5N, GM250T5G, GM250T5NG Systems GM250 JOINT KIT For connection of adjacent Busway sections. One Kit required at each joint. Each Kit is comprised of a housing coupler pair and bus connector set. Specify configuration to match busway configuration.

HOUSING COUPLER: Consists of two, 12-screw couplers – one for the top of the housing and one for the bottom. Housing Couplers are polarized with a stripe corresponding to the polarization of the housing.

BUS CONNECTOR: Copper blades secured to insulating mounting plate. Left and Right set, makes electrical connection between sections.

INSTALLATION TOOL: Used to install bus connector between two adjacent sections of Busway. Busway sections are butted together and the top housing coupler is installed. The Bus connector is inserted, centered, and seated in the slot of the Busway joint. The installation tool is inserted into jointed intersection and rotated 90º forcing stabs into female conductors making a ‘springpressure’, secure electrical connection. Bottom housing coupler is then centered and installed.
