So you have a probably 20kw unit with 2- 60 amp breakers but it could be a 15 kw unit, usually they have a 60 and a 30. This would be more inline with the 90 amp breaker. The 90 would hold with 20kw since the load is around 83 amps but it is not compliant. My bet is it is 20kw with 2- 60amp breakers
