Hello, my name is Efrain Ramirez, Lighting BDR for Horizon. In this period of instruction, I’m going to be telling you about wiring steps and procedures.

This period of instruction is going to be over LED steps and procedures using the LED Hub Method.

Home run is a circuit ran from your transformer straight to your hub or the first fixture. When running your home run, use 12/2 wire from your transformer straight to your hub or your first fixture.

Laterals or legs. That’s a wire from your hub or the first fixture to five fixtures or less. So don’t exceed five fixtures on each leg.

Now you can daisy chain up to five fixtures per leg from the hub or first fixture, but make sure you don’t exceed 50 foot. This is the 5/50 rule.

So you can run as many legs allowable per home run but make sure you calculate the voltage drop. Down below there’s a formula there and don’t exceed the home run wire capacity

VD = ((L x W)/WC) X 2

Now for instance, here we’re using 12 gauge wire. Don’t exceed 192 watts. That’s 80% of your load.

Last, check your voltage at the hub or the first fixture. Ensure that the proper voltage is between 12v and 15v.

And importantly, when designing wire runs and selecting a transformer, ensure that the voltage taps available on the transformer are sufficient. Make sure you have a high enough voltage tap on that transformer to compensate for the voltage drop.
