I went on to apartment complex to do some work and saw where someone installed 8/3 seu alum to a A/C unit. I know it fails because it is not protected from physical damage. My question is can it be used as a branch circuit conductor to feed the A/C unit?

Permitted as a branch circuit wiring method:

338.10 Uses Permitted.
(A) Service-Entrance Conductors. Service-entrance cable
shall be permitted to be used as service-entrance conductors
and shall be installed in accordance with 230.6, 230.7, and
Parts II, III, and IV of Article 230.
(B) Branch Circuits or Feeders.
(1) Grounded Conductor Insulated. Type SE service-
entrance cables shall be permitted in wiring systems
where all of the circuit conductors of the cable are of the
thermoset or thermoplastic type.
(2) Use of Uninsulated Conductor. Type SE service-
entrance cable shall be permitted for use where the insu-
lated conductors are used for circuit wiring and the uninsu-
lated conductor is used only for equipment grounding
purposes.

I have used SEU Alum cable to wire a Double 2pole 60amp furnace/heat pump and it passed inspection. SEU Alum cable does not require physical protection unless its used as a service feeder in a driveway. Also luckily the furnace did not say anywhere that copper conductors were required at the termination point. Sometimes motor loads and equipment will be labeled as such.

The NEC takes the reasonable position that any connection method or device that does NOT say that it is good for Al is only acceptable for copper.
