I have purchased several of these switches (80 & 100 amp) over the past 2 years. I have found that 80 amp circuit breakers operate between 45 and 55 amps and 100 amp switches operate between 75 and 78 amps. They appear to be good jackhammers, rating aside. I tested the inrush current with different meters to be sure that the meter wasn't the problem.
