Installing Direct-Wired waterers in horse barn (breaker to waterer directly)....
I want to install GFCI breakers, but I'm concerned about the distance with 1 waterer.
2 waterers will be about 75' from subpanel.
1 waterer will be about 350'
Do I need to install a second subpanel for the waterer 350' away?
What is the distance the GFCI breaker will correctly protect without false tripping/issues?
