The Domus TRAK 3-circuit live right end is the component thatbrings mains power into a track run at its right-hand end.4011040mm, 240V, IP20, inblack or white.

There is a left-hand version as well, and they are notinterchangeable. Both are 4011040mmand nothing on either record explains which you need.

Here is what decides it. A 3-circuit track carries three live conductors in a fixedorder along its length. The feed has to enter at the end where your supply cable arrivesand present those three conductors the right way round, so that the fitting you set tocircuit1 is on the circuit your electrician wired as1.

Get it wrong and the track still works but your three switches control the wronggroups of lights, which is discovered at fit-off and fixed by swapping the feed.

Tell us which end of the run the cable comes in at, and which way the track faces, and we willconfirm left or right before you order. It is a two-minute question and a wasted tripotherwise.

The current rating is not recorded, and here it governs the run

• A live end is where power enters the track. Everything hanging on the run drawsthrough this one part, so its ampere rating is the ceiling on the whole layout regardlessof what the track itself is rated for.
• No ampere rating appears in any source we hold for this component or for any of theother TRAK parts seven of them now. Domus’s own description calls the systemcapable of high power loads and states no figure.
• The datasheet attached to this product is the track’s, not this component’s its parts list contains the track lengths and not this part.
• Tell us the fittings you intend to hang and the total run length and we will get therating from Domus before you commit to a layout.

End feed or centre feed

• An end feed (this) carries the entire load through the first metre of track. Simple,and right for a short run or where the supply is already at one end.
• A centre feed splits the load two ways, which roughly doubles the practical run lengthfor the same feed. Right for a long run, or where the existing ceiling point is in the middle of theroom.
• Tell us the run length and where the cable comes in and we will say which issensible.

What else a run needs

• Track lengths 1m surface-mount and other sizes.
• A live end (this, or the left-hand version) or a centre feed.
• A dead end to close the far end of the run.
• Joiners straight, mini straight, or angled at every junction.
• A track run is never just track. Any one part missing stops the job on the day.Tell us the total length and shape and we will list every piece.

What three circuits gives you

• Three separately switched circuits share one physical track, and each fitting is setto one of the three when it is clicked in.
• One run, three lighting scenes in retail: window, general, feature. Over akitchen island: task, pendants, accent.
• Three circuits means three switched supplies arriving at this end. That is morecable and more switching than a single-circuit track, and it has to be planned at rough-in rather thanfit-off. Tell your electrician before the ceiling closes.

Where it works

• Feeding a track run from its right-hand end.
• Short runs, and runs where the supply is already at one end.
• Retail, galleries, studios and kitchens where three scenes are wanted from one run.
• Indoor only IP20; track carries exposed conductors by design.
• Do not plan a load until we have the current rating from Domus.
• Confirm left versus right with us before ordering.

Specifying it

3-circuit live end feed, right hand. 4011040mm,240V AC, IP20. Black (22156) or white (22157). Brings mains supply into a track run at itsright-hand end. Part of the modular TRAK 3-circuit system.

Current rating, maximum load, conductor configuration and material are not recorded in anysource we hold, and the datasheet attached to this product is the track’s sheet, not thiscomponent’s. A left-hand version exists with identical recorded dimensions; nothing ineither record explains which you need.Tell us which end the supply arrives at, which way the track faces, and what you are hanging, andwe will confirm both the hand and the rating with Domus before you order. Warranty 3 years.

Questions

Do I need the left or the right end?

Ask us it is a two-minute question and a wasted trip otherwise. A 3-circuit track carries three live conductors in a fixed order along its length, and the feed has to enter where your supply cable arrives and present those conductors the right way round. Get it wrong and the track still works, but your three switches control the wrong groups of lights, which is discovered at fit-off. Tell us which end the cable comes in at and which way the track faces.

How many fittings can the run carry?

We cannot tell you yet. A live end is where power enters the track, so everything on the run draws through this one component and its ampere rating is the ceiling on the whole layout regardless of what the track is rated for. No figure appears in any source we hold for this or any other TRAK part seven of them now and the datasheet attached is the track’s rather than this component’s. Tell us the fittings and the run length and we will get the rating from Domus first.

Should I feed from the end or the centre?

An end feed carries the entire load through the first metre of track, which is fine for a short run or where the supply is already at one end. A centre feed splits the load two ways and roughly doubles the practical run length for the same feed right for a long run, or where the existing ceiling point is in the middle of the room. Tell us the length and where the cable arrives and we will say which is sensible.

What else do I need for a run?

Track lengths, this live end (or the left-hand version, or a centre feed), a dead end to close the far end, and joiners at every junction. A track run is never just track, and any one part missing stops the job on the day. Tell us the total length and shape and we will list every piece.

What does “3-circuit” mean for the wiring?

Three separately switched circuits share one physical track, and each fitting is set to one of them when it is clicked in so one run gives three lighting scenes. It also means three switched supplies have to arrive at this end, which is more cable and more switching than a single-circuit track. Plan it at rough-in rather than fit-off.

Can it go outdoors or in a bathroom?

No. It is IP20, indoor dry areas only. Track carries exposed conductors by design, so this is not a rating to work around.

What is the difference between this and a joiner?

This brings mains power into the track; a joiner connects two lengths to each other. A run typically needs one feed, joiners at each junction, and a dead end to close it. If your feed is at a junction rather than at an end, the centre feed live joiner does both jobs in one part.
