LOL, 10 gauge wire is 10 gauge wire regardless of strand count.
Wires with more strands has absolutely nothing to do with "what voltage it is good for".
Certain wire is no better for DC current than another, absolutely no difference.
It will be more flexible for bend and terminations, but thats it.
 
i beg to differ on the strand count having nothing to do with the voltage number. if that was the case why are your houses wired for 120/240 with single strand wire. put the same thickness multi strand wire in its place and stand back and watch your house burn to the ground. wire is just like a fuse, the higer the voltage and current flow the bigger the fuse and its element has to be. if you are running a 12 volt systen run auto wire, if you are running off a genny run house wire. save yourself future troble down the road and do it right the first time. and before all the backyard experts disagree i do work for an electric utility company and have a little knowledge about running power to places.

Current is the factor, yes stranded wire tends to have slightly lower ampacities than solid wire, but hardly results in a house burning down, but this simply proves my point. A wire rated for 120v is fine for ANY voltage below that, be it DC or AC, it is a matter of Amp draw...Period.
FYI, Im a Master Electrician and Electrical contractor, so I know more than a little about the subject.
Every house in America is Fed with multi strand wire, LOL
 
IMO 2 advantages in using marine grade wire:
It's flexible and easy to work with. 6 guage marine duplex is super easy to work with when running troller wires.
It's tinned and doesn't corrode as fast as plain copper wire does in a marine environment. Connections stay clean and trouble free longer.
I don't use it for everything but have been very impressed with marine grade wire everywhere I've used it.
 
i got a bunch of 10ga off ebay for 1/2 what i wouldve paid at lowes or autoparts store.

other than that i caint help but add to the rest of this argument. its been my experience to go with the grain on this one : boats, automobiles, ect. all use multistrand wire. even my boat. im sure the tinned chit is just sweet, but when i looked at the price difference i could replace the copper 2.5 times before reaching the price they want for tinned. no disrespect OBG.

I hear ya! The price difference doesn't always fit in the budget here either. Bout the only place I use marine grade exclusively is for troller wiring since corroded connections became a thing of the past when I switched to tinned wire. I have done a bunch of troller boats through the years and have not had to replace/repair a single battery or troller connection since I started using Anderson connectors and 6 guage marine duplex. Can't say the same for boats that I used wire that I bought at the electrical supply house on though.
 
im in the process of wireing my front deck. i ofcourse went way overboard on wire size and was worried about my connections. i will get some pix up here in a day or so of the solutions i came up with. i made a odd junction to make my heavy wire split into all the supply lines to my switches for my light bar.
