During the winter we have serious problems with our electrical system that is becoming dangerous. I don't know exactly what question to ask that could help us so let me give you some of the symptoms. We are a liveaboard community in the mid-Atlantic so it gets cold here. Most boats have 50 Amp panels. Some have 2 separate 50 amp panels (I am one of those.) During the early morning and evening when most are home, our breakers start popping, panels rattle, the electrical lines from the pier become warm and apparently some have overheated to the point of arcing and fire. I don't have to tell you how devastating a marina fire can be. A qualified electrical company has certified that all lines are to code and compliance. It's obvious that many boaters are adding space heaters during morning and evening and they are unaware that they are overloading the circuits heavily. Any suggestions of how we can get a handle on the usage? Is there an instrument that can test each boat for their particular maximum draw? Those in the 'know' here say it is a decrease in voltage that can fry compressors, motors, etc. and that the electrical utility should 'give us more voltage.' Is that a fault of the utility? Doesn't seem right to me--can they 'increase' it? If I can't solve the whole marina's problem, how can I best protect my boat and my appliances? I use a lot of electricity but I also have two 50amp lines and they seem to be balanced for load (i.e., 2 heat pumps, 2 heaters (occasionally), washer, dryer, stove, HW heater, microwave, stove, fridge, lights/TV, etc--generally balanced between the two panels.) In the wintertime I only wash or dry clothes during the day when there are fewer people in the marina and only wash or dry since they are on the same panel. (During the summer I can wash AND dry with no problem.) I have become adept at taking some appliances off line but occasionally I'm surprised and blow a breaker. I also have one new 220 heat pump whose electrical cord heats up occasionally if I forget to turn it off...I'm real uncomfortable with depending on touching the plug to see if everybody on my pier is home!! I would like to do a full audit of my own appliances and wonder if there is, again, a meter that I can get to determine each appliance's draw? What would I be measuring? voltage? wattage? ohm resistance? amps? I'm afraid I don't even know what question to ask. Thanks for any help.
