Wire gauge?

I am planning on installing a BlueSea fuse block sometime next week and first thing I am going to hook up to it is my topper light and possibly some additional 12V and USB outlets in the bed. So that would probably be 12-15 feet of wire.

I am thinking 12ga wire. Overkill or just good enough?

 

14 gauge is probably fine but bigger is okay.

 

sweet, thanks!

 

I would go even thicker. Depending on how many things you plan on running. If it's smaller accessories then you don't need much. I am using the box for led light bars so I ran I think it was 4 ga wire just to be safe and not do it again. I would go 10ga for accessories. The main power wire to battery that is.

 

If you ever want to run a fridge back there or anything like an inverter. I would recommend, at a minimum 8 gauge. More like 4 gauge.

What I did for the rear was run 2/0 gauge to the rear to a distribution block, then shorter leads to the accessories I want to run.

I like to think ahead and only do things once.
