Using breaker as AC disconnect

[Dansos]

hi guys, we currently have two (2) 10 ton AC units that my client wants removed and replaced with four (4) 5 ton units. Currently, 2 60A circuits are feeding the disconnects and powering the units. Can I take the existing wiring and power a 60A main lug outdoor panel and run 2 separate breakers to feed 2 units from that panel? I have only ever used fused disconnects for outdoor equipment. Is there a code violation doing this? The panel box will be installed directly in back of the condensers.

That is fine, assuming the new feeder has the ampacity required.

and assuming the HVAC unit nameplates show circuit breaker over-current is acceptable.
There are some units that call for "Max Fuse" without giving you an option for circuit breakers.

And that the breaker is "within the line of sight".

When I was a cub, I remember several times being on AC jobs where there was a double disconnect. Do they still make those? Usually they'd be fed by a #4, 2, 1 SE.

Thanks for the replies. The name tag states fused or breaker and the panel will be approx 36” to the side of the pad where the units are.

The ability to Lock it Out is all that’s left.

I don't think that is required.

You must also make sure that the breakers are rated as type HACR. Most are these days but check anyway.
