I am building a tiny house intended to be off grid, and to connect all the various AC circuits to the 12v main battery I thought a MFJ-1112 DC power strip would work fine. Then my uncle, who has a lot of electrical knowledge and is helping me with the electrical system, took a look inside and was shocked at what he found. The + and - sides are connected via a single flimsy serial wire connection directly to the DC input. There are two tiny ceramic disk caps connecting each side to ground, and a single tiny cap as a shunt. The three caps are only marked with "104Z". My uncle handed it back to me and said it was worthless. His response was to buy a bunch of parts at Home Depot with the intention of making a homebrew bus out of a couple cheap terminal blocks and a bunch of various lugs and crimp connectors. I personally am wondering if I could simply cut out the wires and caps from the 1112 and make something much sturdier. I'm thinking 12 gauge stranded steel wire of the type Mouser sells and a lot of semi-HV caps to use as shunts and such and probably a few varistors to act as circuit protection, or possibly even a fuse. The electrical system in this tiny home will use 20A Siemens circuit breakers for all AC plugs with a maximum draw at any one time probably not more than 16A or so. (There will be a separate DC circuit for my ham rigs.) If you were looking at this with the use I intend, how would you beef it up?
