Hi All. Thanks for all the information I have just got back on the computer, been away for a few days. I’m going to fit a 1000 watt inverter and a 300 watt inverter to run the TV DVD and cooker fan, the 1000 watt is just for tools and hair dryer. I’m going to run 150 amp cable from the battery to the isolator with a inline fuse connected on the positive. From the isolator I will go direct to the switched fuse box buzz bar and then to both inverters. The neutral will be connected from another buzz bar and go back to the negative on the battery. Both inverters will be protected by a r.c.d. which in turn protects me from getting a 240 volt shock. I have got 12v white led lighting, two pumps and a small amp for the Arial coming from the same fuse box, my other fuse box works the horn, headlight and navigation lights and is connected to my starter battery. By the way the boat is a sail away from lb so I have got a lot to do, any advise will be welcome. Colin.
