Okay gentlemen, here is the problem. The client wants to put air conditioning on his boat, and power it with a small portable generator. The boat will also need an AC power backbone, and breakers, along with a GFI outlet in the cabin. Oh yeah, the owner has an existing small AC inlet that he may still want to use to power the charger, and or use the new shore power/generator system. Oh, I forgot we have to do everything in 20 amps because that is all that is available at the dock.
What do you think? Yes Bob? "Well I don't know boss. The big problem with using a small generator is the surge load when the air conditioning compressor starts, but maybe if the generator is large enough it might work. You will also have to have some sort of way to stop the small charger outlet from back from feeding into the AC system. I dunno, all of that with only 20 amps? It sounds dicey to me, maybe it can be done."
Good waffle there Bob. Do you want some maple syrup on it? What do you think Harley? "Sure Chief, it's doable with some forethought. There are some technologies available to deal with the air conditioning start up surge issues, and a breaker could be installed to control the AC back feed issue." Sound good Harley, and Bob quit playing with that slide rule, you're driving me nuts.
