12/3 Gauge Marine Wire

I used this wire in an RV application to replace undersized house type romex that was used by a professional installer when we had an battery/inverter electrical system installed in our Sprinter van. It is a major improvement over the solid conductors used in Romex. Easy to route through holes and around bends. Very easy to stip and terminate with crimp connectors and screw termination. Great wire.

This wire has good primary and secondary insulation. Tested it’s flexibility after in a -15f freezer for several hours. Very flexible even cold. 30-32 amp load was pulled across 10awg 30ft run with minimal voltage drop approximately 3vac on 245volt circuit. Wire temperature went from 70f to 90f after a hour of constant load. Copper was tinned for marine use and helps with resistance. This is basically stranded romex with better insulation. No sunlight UV resistance test based on interior use. Would recommend this product.

Not a substitute. True marine grade tinned wire.

Well made.

This was perfect for my vintage camper renovation. I was starting from scratch on a tiny 10 ft camper and needed something safe and affordable that I could maneuver in tight places. This was perfect!

I needed this for an RV application, and it worked well. The only reason for not being 5 star is it's not that easy to remove the outer sheath as compared with normal household Romex. It doesn't just tear away once you start a split. So it requires a careful slicing over the ground wire, which is fortunately right in the middle. Maybe there's a reason that's necessary for marine applications? Not sure, but not that big of an annoyance. I'd buy again if I needed more.

It was good wire it did the job and I gave it to my Electrician for my ring doorbell. It was inexpensive and came in a relatively short amount of time. Good quality.

Great wire at great price
