CrossPlainCrazy, I like to use the Blue Seas products too! I got use to them while repairing yachts. Great quality at a good price (for marine quality). They're located in Bellingham, WA and they have a great customer/tech help group. I had to call them once when trying to connect 3 onboard gensets,a 220v line and a 120v line from shore power all to one of Blue Seas switch boxes. One Genset had to come on when shore power failed, then the other 2 came on as the demand raised. The 202V line activated when the A/C was on, or the clothes dryer. That box was 3FT X3FT and there was so much stuff in it, there wasn't enough room to slide a credit card in. But they helped me wire it in.

I am showing my ignorance here, but when wiring the fuse panel. There is only one source of 12 volt power, which is fed by the battery, correct? Then the fuse panel distributes 12 volt power to each of the fused connections?

You are correct Hillbuddy, that's the way it works. I defer to Gary, as the Bump Tricklician, for the Kingdom. Anybody who can wire 3 generators in a yacht, is way over my level. My theory is that smoke makes electrical things work. If you let the smoke out, its done for. What I know is this.. A fuse panel is for circuit protection. One main supply, from the battery, should make one side of all the fuses 'hot'. The other side of the fuse supplies the circuit with power. In most boat power, as opposed to automotive power, each boat circuit needs its own ground. That's because most boat hulls do not provide a common ground, as does a frame & engine in a car or truck. Gary, help me out here, if I get off track..
I have marine fuse panels in both my boat, and my dune buggy, which are similar, in that my buggy's body is fiberglass, and not part of the ground circuit. Everything is grounded to the metal frame, starting with the battery. Trucks are easier..
There is an inexpensive book I recommend.. "The 12 Volt Bible"... Amazon for about $6.00, or used to be... Hope I helped amigo

It's awesome to hear that you have worked with the brand though and I thought I was doing goo with my electrical rewiring the whole truck and modernizing the connectors and simplifying it and replacing the old dry rotted wires, but damn man you would of done it in a couple of days lol.. Great to hear positive things about a company's product that I use and know it's made here in the USA Good book recommendation bajafishnut

Sorry about the confusion Hillcountryflt. I got a little carried away and off topic. The "panel" or "box" that I was referring to was like your main fuse box in your house. That one box had 12 volt, 220 and 120 volts all in one place. The switch I was talking about was a rotary switch that had 5 (levels) places to hook up each item(Gen#1, Gen#2, Main Gen, 220 shore power, 120 volt shore power). Then the 12 volt section had it's own switch and fuses. Setting that stuff up so only one item is sending power at a time,and in the correct direction is often tricky. Fires are the number one cause of boat emergencies.

CrossPlainCrazy, I never was very fast at electrical work, but I never had a failure or a fire. Like Baja says"Moving at the speed of right". Although I bet other guys have heard a wife or girlfriend say something about "are you still working on that?" or "aren't you done yet?" I know I've heard it, several times!-LOL But anyways we were saying that good equipment makes the job easier.
