Hi,

I am looking to purchase 10 feet of 8-2 landscape wire because I have to move an already installed landscape light.

I have searched everywhere including local stores and unless you need 100' or more cant be found.

Any idea where I can buy just 10' of 8-2 landscape wire?

use 2 pieces of 16-2

using 2 pieces of 16-2 will not result in the same resistance, it will be quite a bit higher which is not what I want.

I could use two pieces of 10-2 but finding 10' of that is just as hard. Using 2 12-2 is close as well and I guess if I can't find 8-2 is what I will use.

Given that I'm running 10', 300W at ~12V here's what I think it looks like:

8G 0.15V drop
10G 0.25V
12G 0.4V
14G 0.625

Using 2 wires will cut the voltage drop in half.

I don't care what you use.

Nice reply moron. If you don't know what your talking about, and obviously you don't, you shouldn't be offering up answers.

As expected another idiotic response. Thanks to another member if this forum I found what I needed. Use two 16-2... Know that's funny. How do you come up with that? Let me guess 8 x 2 = 16??

Emdoller,

I am trying to understand why you need 8/2 for one landscape light? I have never seen a 300 watt fixture on the low volt side. What is the wattage of the lamp in the fixture you are moving and have you taken a voltage reading to see how much available voltage you have to work with currently. I am just saying because I rarely ever use any lamp over 35watts in any of my fixtures and you wouldn't need anything bigger than 12/2 really to simply add onto a fixture to move it. Your voltage drop is negligable at that distance and load.

300 watts at 12 volts is 25 amps Thats a lot for parallel 16's

14g @ 10ft with 68 degree temp at 25 amps is a drop of 1.3 volts.
Go to lowes and get 8g thhn stranded and be done.
