I am using 12 post lights per cucuit, with 60 watt floresent bulbs. The longest run is less than 1000'.

I have used #12 and 14 NM Romex in PVC conduit (wrong type I quess), the calulation shows that with voltage and amp loss is acceptable for what i am doing.

The 2 inch PVC is above ground and will never be under water, it is attached to a 5 foot fence.

It would probably be cheaper for the owner to hire an Engineer to do the calculations properly, than to hire you to do it over when it doesn't work.
You did say 1000', right? One-Thousand feet?
It will not work.

This project is doomed. Type NM cable is not listed for wet locations. Exterior on a fence (even in conduit) is a wet location. What about conduit fill? You need to caculate the area of all of the cables to see if they will not exceed 40%, then you have to derate if there are more than 6 CC conductors................................................Blah Blah Blah
I don't care if it works right. but it needs to be NEC compliant and safe.
P.S. it won't work right.

thanks guys,

i have already done this on my farm and everything works great. The lights come on at dusk and turn off after a couple hours. The is no noticalbe difference between the light from the first light and the last.

I am using 2 inch PVC and 3 wires, hot, neutral and ground. I realize than NM Romex is wrong and will correct it in the future.

The volt and amp loss is minimal even at 1000' and a light every 90 feet.

So if I use #12 UF single wires for ever conductors and run two curcuits (10 bulbs on each curcuit) in the 2 inch conduit there would be no problem with this concept.

In your profile you state that you are a farmer.
What type of farming do you do?
How much do you plant?

To advise you on your lights, hire an electrician!
