For both ac and dc low voltage generally the maximum acceptable voltage drop is 10.
12v landscape lighting voltage drop.
The below charts assume this.
Voltage drop is a decrease in the voltage created by internal resistance to the flow of electricity through the wire.
We will compare the most common wiring methods below but before we do that let s consider the nemesis of wiring any landscape lighting system.
You will also need to apply.
