JW...I can figure for voltage drop....I have a question for you --- would a junction box make sense here? and forget about a subpanel.....Run #6 or #8 wire from main panel to an outdoor junction box? and then wire to two more junction boxes for each waterer?
I have three separate fenced in areas for the horses...where would you install/mount the box if you think this is an option?
Also, would you install inline GFCIs for this configuration (or 1 inline GFCI at the first junction)...and how/where would you mount them? (would have to be outdoor inline GFCIs obviously)
Thanks for the input
Horses are curious by nature. Anything strange they will eventually start messing with it even chewing on it if they like the taste.
However I wired the circuit I would ensure that no part is within their reach. Should you have a wind sucker and it can reach the post, box, or panel you are guaranteed a dead horse.
You seem to be dead set on installing these but I come once again trying to convince you to think of other methods. When new these things work great but they age at a very fast rate and become damaged. You will spend endless hours resetting the GFCI device to the point they start to fail. At this point the horse has already been hit and it takes little current to train the horse to not use them. One horse minus water equals a vet bill.
The ones I installed were removed in less than 6 months. I then tried the ball cock and it failed quickly. All I had was a big mud hole in front to the tub where the failures let water flow all day.
It didn’t take me long to figure out that I was feeding the horse twice daily so he got water twice daily. His tub was emptied and washed twice daily, he like that a lot better than standing in mud or jagged ice to drink.
