I’ve got 500 feet of 1 inch conduit buried above my waterline. I stubbed it up every 20 feet. My plan is to run some copper wire through there for some sort of low-voltage lighting system. I can split this distance in half at the cabin, resulting in approximately two, 250 foot runs. I’ll use whatever works with my final lighting design and abandon the rest.
I understand the blue seat capacity charts. And I see the distinction between 3% voltage drop for critical loads and 10% voltage drop for non-critical loads.
Some of the led lights I’m looking at have a pretty wide range of acceptable voltages. E.g.: 10-60 volts.
What happens when there is greater voltage drop? Does the wire get unacceptably hot?
I’m trying to grok what happens if I have a long run of wire, starting at 48 volts, but delivering say 10 volts at the end of the run.
As I type this, I’m thinking there is some relationship between ampacity an voltage drop I don’t get.
Can anyone point me in the right direction to clear up my muddy thinking?
Thanks
