Okay here's the thing... GFIs do NOT trip due to overcurrent. They are not designed to do that. You can plug a hundred gazillion things into them and as long as none of them have a ground fault, they won't trip.
GFIs trip due to ground faults and ground faults only. If the GFI is tripping then that is what you have, or a nuisance trip. Since you say that this cord trips any GFI instantly and that nothing else trips your GFIs, then it is likely not a nuisance trip, but a legitimate fault condition that it is detecting.
GFIs are designed to trip when the current flow on both sides of the circuit are not equal, because the current is being diverted to ground somewhere... hence "Ground Fault." Of course their primary purpose is to trip if your body forms a fault path, but any time a piece of equipment has either a slight or a total short to ground, it can cause this. Salt creep is notorious for this.
Likely culprits?
- Salt creep on the lighting sockets or any other electrical connection
- Frayed cords exposed to water
- Internally damaged ballast components that are leaking current to ground
- Salt creep built up in power strips, etc...
Do you think it's possible that the length of the powercord from the ballast to the outlet could come into play if it's too long? Wondering if the amount of voltage required by the ballast could cause a short laps in the current traveling from the hot all the way up and through the ballast and then back to the wall?
