I think this project can be considered done with the exception of the punch list
.
Lessons Learned:
1. Tough project. I can't imagine being an Installer for a living. Not only was lots of tight space "yacht yoga" involved but the learning curve and tying everything together was a lot more difficult than it seems on the surface. Let's just say my mettle was tested.
2. If you have the option between "saving money" by using dual 1/0 versus 4/0 - save yourself the trouble and go 4/0. Having to offset the lugs on the 1/0 caused me no end of headache.
3. The battery monitor is an awesome and necessary device even if you don't install all this other crap™
4. Having the right tools and lugs makes all the difference. Making the battery cables was a breeze because I had the hydraulic to borrow - if I had to have these made elsewhere it would have slowed my tortoise like progress even further.
5. Along the same lines as point 4 - Marine cable is tinned and finely stranded and as such is considered Flex cable so don't go to your local electrical wholesaler and expect number 6 AWG butt splices to fit very well even if they say they are meant for stranded cable. Same for ring terminals. Let's just say I figured this out the hard way.
6. Hole saws are measured OD (outer diameter) and electrical fittings are sized ID (inner diameter) thus an electrical fitting of 1-1/2" will not fit in a 1-3/4" hole.
7. Just because it looks like a cable raceway goes in one direction doesnt mean it actually does. Carver sure made some head scratching design choices much to my amusement and irritation.
Thanks all for your comments throughout the process. I think writing this kinda kept me on track.
