dc circuit length?
(OP)
Does anyone know how far you can effectively run 24VDC. We have an application where we need to run it about 300' to a 1/2 amp load. Thanks

First find out the actual operating voltage requirements of your devices. Make sure you are clear on the round trip nature of your proposed circuit.

RE: dc circuit length?
Just yesterday I was playing with a GPS I had pucked up for $5 bucks with a battery case problem. My bench power supply had a 5 ohm resistor to jumper to the center connector so I could use a standard banana pair. The GPS draws less than .06A, but I couldn't get it to turn on till I shorted the 5 ohm resistor!
RE: dc circuit length?
sreid's calculation is based on your initial data of 0.5A.

600' (2x300)
24VDC
1.0 amp @ 3% drop => 8ga
0.5 amp @ 3% drop => 10ga
1.0 amp @ 10% drop => 12ga
0.5 amp @ 10% drop => 16ga
NOTE: Please be sure to adhere to ABYC standards
NOTE: Use ANCOR tinned & stranded wire in marine applications
