Rough In Wiring
Example:
25A max per NEC 411: use #10 AWG min
For 20A, use #12 AWG min
For 15A use #14 AWG min
Please note amperage may increase with higher taps.
L.V. = Class 1 wiring per NEC - wire must be sized to be
equal to or greater than shown.
When the voltage goes down by a factor of 10 (120V to 12V) the
amperage goes up by a factor of 10 (2.5A to 25A)

The neutral must be clean.
Run a “virgin” neutral for each PSC.
Low Voltage Runs = High Amps
Secondary Breaker Amperage
Keep Runs Short! Get The Tap Right!
Get The Wire Gauge Right
Both primary and secondary wiring to be Class 1 per
NEC unless Class 2 option is ordered
