The previous owner showed me how to turn off power at the boat and the dock before disconnecting or connecting the shore power cord by using the big rotary switch that selects power source. Every other position is "off". Now I just read in the Hatteras owners manual that you should first use the circuit breaker for the shore power inlet and then switch the big rotary selector switch to off. I've been doing it with just the rotary switch for 3 years - very convenient. The question is, can I be damaging the rotary switch contact points due to a "hot disconnect"? I always turn off anything big like A/Cs first. Do you others use the shore power inlet circuit breaker to turn off the power to the boat first?

Thanks,
