Again, thanks for all the responses.
Just a couple of points:
1. Local codes can dictate the type of breaker used.
2. I've been plugged into 30 amp service many times and have had the electric HWH running along with the AC and haven't tripped circuits. Now, if the breaker had reset, I would have flipped the water heater to propane.
3. I tried resetting the breaker without any load at all, i.e. I disconnected the PI EMS. The owner had to press very firmly at the off position of the breaker, and then it did reset. Is the breaker faulty....I don't know.
Now, if I'm plugged in with the 50amp adapter, and the PG EMS is plugged into the power post (it's the portable model), I would think that if there was a short and 50 amps was sent to the PI EMS, the EMS would do it's job. That being the case, I don't see any danger in using the adapter! Any comments??
