Rough In Wiring
Equalizing Voltage Drop
When installing multiple fixtures or loads from a single remote PSC,
it is important to have approimately the same voltage at each lamp.
Many installations require different length runs to the loads which
may require different wire gauges to equalize the voltage. It is
important to have approximately the same voltage at each lamp so
the light output appears to be the same. Use Q-Tran’s Voltage Drop
Calculator to easily determine the correct wire gauge.
3 Key Points you must know:
1 - The voltage of the lamp specified
2 - The amperage rating of the product
3 - The maximum wire gauge that can be terminated at the load. A
number 6 or 8 gauge wire, for instance, can not be terminated on
most L.V. products.
Diagram A - For 12V track, rail, or cable system that is rated for
25A requires a minimum of #10 gauge wire. Runs should be
approximately the same length.
Diagram B - For LV cove lighting, the VDC might show you to vary
the wire gauge to equalize the voltage at the lamp. Running the
same gauge wire to all runs may be wrong.
Diagram C - For recessed or mono point fixtures powered from a
single PSC, it is a recommended that all secondary runs be the
same length and the same gauge; EQUAL LENGTH - EQUAL
GAUGE. All surplus wire must not be coiled but made into a long
loop.
Diagram D - For commerical installations requiring conduit, this
diagram shows an alternate wiring method. Also applicable to
residential installations.
