My PowerMax converters (100a, 75a, 55a) have all met and exceeded their amp ratings (103, 76, 56). There are two main reasons for not reaching converter rating:
1. Using #8 output wiring. Needs #4. Their instructions are not clear about that.
2. Low 120v input. It runs but at lower amps
EG my 75 runs at 76 off generator, but at 67ish on long #12 cord from stick house.
Same thing with my old Parallax 4455 I had some years ago. It did 55 amps on #8 but did 60 amps on #4.
The PowerMax units I have all ramp up their amps on start-up as seen on the Trimetric, so they reach max amps a tad after getting going.
