Roadway decorative lights with GFCI outlet

Does anyone have any recommendations on calculation of voltage drop for 200W decorative lights with a GFCI outlet attached on them to the same circuit? I assume they will be used to place Christmas lights or decorations.

This is the first time I've come across a request of placing outlets on the poles. My initial thought is to just assume that 100W would be connected to the outlet and run the calcs with that, however I am curious if anyone else has opinions or has worked with this before.

What is the distance of the run? The fact that a GFCI is to be installed dosent have any thing to do with the VD calculation.

So are you talking about a circuit run of over 8000 feet? If so you will have a HUGE voltage drop problem regardless of amperage!

Once its determined how many poles can be fit on a circuit (ie. total voltage drop), the remaining poles will be placed on additional electrical service point(s). So, voltage drop should not be a problem.

If you have 1 amp per pole. Then from the source you can run 587ft. of #8. So if you can get 4 poles in this run it would be OK for a load of 4 amps with out too much voltage drop.
Hope some one has $$$$$
