What it is and how it is builtThe
AST-TRK-H-LEC-BK is a live end connector — the energized feed — for the TUROLIGHT ASTELLA track system in
H-type, single circuit configuration. It slips into the open end of a track section and becomes the electrical entry point of the run. Inside the housing are screw terminals for line, neutral and ground; outside, set screws lock the connector mechanically to the rail so the copper contacts stay firmly engaged. The
black finish is chosen to blend with black AST track, giving a continuous, uninterrupted line across a ceiling instead of a visible junction.
Electrical and installation detailsRated
120V, 60Hz, 20A, this feed serves a
1-circuit (P + N + PE) track, which means a single switched circuit powers every head on the run while ground is carried the full length. It is a
Class I, IP20 component for dry, indoor locations. Installation follows the printed instructions: shut off power at the main panel or fuse box before touching the track or accessories; position the track over the outlet box and mark the mounting holes; on drywall or plaster drill
5/8" holes and use the supplied toggle bolts, or standard
#10 wood screws (not supplied) on wood surfaces, with the smooth underside of the track facing the ceiling or wall. Then cut and strip the box wires to
3/8", secure them under the screw terminals, loosen the set screws, slide the connector into the open end of the rail respecting the polarity line, tighten, install your lampholders, and only then turn the power back on. Local installation requirements must be respected.
Polarity, grounding and safetyOn H-type track the ground tabs of the connectors must be prepared before sliding onto the non-ground conductor tab of the section you are joining — select and cut the correct tab before insertion (copper on one side versus copper on both sides tells you which). If the wrong tab has been removed, the connector must not be used, because grounding will no longer be maintained. To reduce the risk of fire, once all rails and connectors are installed, make sure a dead-end fitting is slid into every open end of the track and that all set screws are tightened before energizing. Only use fixture assemblies marked for use with this track. To reduce the risk of fire and electric shock, use only fixture assemblies marked for use with TUROLIGHT track.

Applications, compatibility and documentationUse it anywhere you build a
track lighting run: a 4 ft rail of adjustable heads over a kitchen island, a retail perimeter washing merchandise, a café counter, a hair salon mirror wall, a gallery hanging, a home office or a finished basement. Because the AST sections come in several lengths, one live end connector powers whichever layout you assemble — pair it with the
AST Track 2 ft black,
AST Track 4 ft black or
AST Track 6 ft black, or with white sections like the
AST Track 12 ft white for longer commercial runs. Other ASTELLA H-type accessories in the same family cover the rest of the layout, including end caps and straight, L, T, X and flexible joiners. The installation instructions and full details are in the technical PDF available in the Documentation tab of this page — worth a read before your electrician starts, so the polarity tabs are prepared correctly the first time.
