so to clarify, you are saying that I can replace 4 single pole breakers with 2 twin 60amp breakers.
then I would be able to run a line (say 6 gauge wire) from one of the new twin breakers to the pool heater location.
but what happens to everything that was already connected to the 4 single pole breakers
I understand the part of replacing the breakers and running the wire for the new heater from one of the new 60amp GFCI
but where my confusion is: are you saying that everything else that was originally connected to the 4 single poles will now be connected to the other 60amp break?
maybe I am slow
but if I remove 4 single pole breakers and replace with two twin breakers in the exact same spot as the ones I removed.
how in the world am I going to have a space available for a 60A GFCI
sorry you have been very helpful and I plan to do this tomorrow but just need clarifcation
