Bruce: Knowledge is Power!. Books and manuals are fun to read.I now have, thanks to the internet a complete manual, operating instructions, exploded views, spare parts list for pretty much everything on my MT50.  For Bob Mc Clearan:  I installed a inverter by-pass switch in Mobile, AL.Ft Pierce City Marina is the place with new wiring on the docks per the new NEC code. I took out the Main 800 Amp Breaker feeding the dock. Now Power distribution was my career and when I investigated the Main Panel I found the SQ-D 800 Amp main had a device that accumulates the ground leakage current from the other pedestals and when it reached the top threshold that it was set for The Main Came off Line and killed the whole dock. So I contributed something to the main. Yes taking my inverter off-line with my inverter bypass switch solved my contribution but now I had no battery charger and got tired of running the genset to charge batteries. Enter: Mike Giannotti, ABYC certified electrician who came over from Vero Beach. He knew what the problem was on the phone. He separated the Neutrals of the Inverter circuits and everything was good.He is a Great Guy who knows his stuff. Yes Jim I could open cover on the inverter and put some leads together  to accomplish the same thing as my inverter by-pass switch, but I like to keep it simple, so I have the By-Pass switch. And had it installed at the right timein Mobile, AL Ya'll Have a very MERRY CHRISTMAS AND HAPPY NEW YEAR Bob KovachCharleston, S.C.
