Wiring interconnect goodies & volt drop loss calculator

[JFinch57]

Other calculators & info

I like the wiring size calculator here http://www.electrician2.com/calculat...cpd_ver_1.html and the conduit fill calculator http://www.electrician2.com/calculat...alculator.html . Use continuous load for solar wire sizing. Also, there is some great general info here http--www.mikeholt.com-instructor2-img-product-pdf-11NEC101-1076-sample.pdf .

and i found some really nifty terminals / terminal blocks for splices and taps for my AC wiring. I had to run about 900' of #6 aluminum wire, and these were some of the few things that are rated for al wire, and easier to use than the Al/Cu split bolts, if you have the right size wrenches.

And for your batteries, the terminal mount fuse blocks by Blue Sea are hard to beat.
