8 OneTrack and OneTrack Backbone Planning and Installation Manual
Electrical Requirements
CAUTION: Electrical installation must be performed by a qualified
electrician in accordance with local electrical codes and permitting
procedures.
• Maximum Feed: 2 x 20 A branch circuits
• Maximum Load: 2 x 16 A (2 x 1920 W at 120 V)
• Supply Wiring: 12 AWG (4mm
2
) feed wires (120 V)
Key Line
Couplers only fit into track in one orientation, creating a "key line" in which the raised key of
the coupler fits into the channel on the track.
Figure 3: The "key" on the coupler fits into the track in one orientation
Consider the following information when planning the key line:
• Couplers will only fit into the track in one orientation. This is important to keep in mind
when purchasing couplers so that the couplers are oriented correctly for the track layout.
(See
Figure 3
below.)
• When planning for the locations of end feeds, be aware that DMX and power cannot be
wired into the same end feed. Install separate end feeds for DMX and power.
• When planning for the locations of mid feeds, ETC recommends that you use mid feeds
to provide power to the track, not DMX. (Using a mid feed to provide data creates a T-
junction, which is disallowed.)
