I am replacing my air handler in the attic with a newer and more efficient model
located in a closet on the ground level. I will start at the main panel for
(hopefully) some clarity. 60 Amp breaker with #6 wire running to a disconect at
the existing air handler. Because of the difficulty of pulling new wire, I
want to know if #8 wire can be junctioned in the existing disconnect and run
to the new air handler?Also , since the new air handler requires only a 35 Amp
breaker in the main panel, will the #6 wire fit in the new breaker lugs? The
new unit does not need a disconnect as it came supplied with an internal one.
Thanks in advance and I hope Iv'e described the situation accurately.

I'm not an electrician, but I've seen my share of items, especially HVAC stuff,

If the run to the old disconnect (external is FAR better) is damaged or brittle,
then #8 is perfect and not at all borderline...many electric clothes dryers are
installed with #10. The #6 should fit the new breaker, they're made for a range
of configurations. In the case that it doesn't, go up to a 40-amp

the store to be sure.
