Default #2 AL SE cable for a 90A steam generator?

I get confused by the NEC. To many options. Help a brother out.

According to the specs, it draws 67 amps but required a 90 amp circuit.

I think you are right. The book I was looking at in the office was 08. The chart listed SEU cable as 90 amps. We don't use a lot of SE cable and I've only heard it called SE, except for the SER(round?) that I used a while back.
