I have an air handler with a disconnect accessible on the front. I want to splice copper to my aluminum feeder within the air handler. Would that follow through with the copper only. THere is enough room to make the splice within the unit.
thanks.

I don't understand this part of your question?

Provided that there is space for the splice and the splice is listed to splice copper to aluminum there should be no problem with doing this.

Most units state copper wire only (this is what the OP means)-- does that mean no aluminum on the terminals or within the unit. It could mean just to the terminals in which case , it would be fine. However if the manufacturers were afraid of aluminum in the unit because of the vibration then it would not be okay.

We would need to find out from the manufacture what the reason for the "Copper wire only" is meant to mean.

My gut feel is the terminals are not listed for aluminum wire.

I will be using copper for the terminal connection, barrel splices from aluminum to copper.
If I remember correctly the "copper only" was in response to HVAC techs who did there own wiring, were using aluminum, with oxide inhibitor, which caused many failures.
Would this be any different than using alum to go to a oven, and connecting copper to the copper wire provided?

The disconnect is a standard 60 amp QO breaker, which can take the alum. wire, but is prohibited by the manufacturer.

What do you mean? Are you saying that the manufacturer will not allow aluminum into the disco? :-? Or is the disco built into the furnace? Either way I believe the intent is for the terminals, as Chris already stated.
 
The breaker is part of the unit, built into the cabinet. It has a plastic cover over the breaker , where you can access the breaker from the front of the unit.
 
the problem is. there is no place to put a disconnect, they have boxed it in a closet wall with just the front exposed. My other option is to put a JB in the attic. Otherwise I would just use a disconnect/ thanks kevin
