12/3 Gauge Marine 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.

Works great

Just like working with romex. Smaller guage allows it to go down between the cabinets and connect the to the LED fixtures. All the mess and junction box is above the cabinets.

Great wire for outdoor use, I used it to install outdoor ring security cameras. This wire is high-quality and came quickly with no issues from seller, would highly recommend this product.

Used it for my van, does the job I need

Highly similar to it's landlocked relative, NM-B aka Romex cable, this cable in 14AWG is great to fish through the limited space available in RV walls and ceilings. I purchsed a 30 ft roll of 14/3. The key takeaway is it's stranded construction allows this to go where solid wire and other cable types can't go. The insulated ground is great in tight, crowded boxes, where a bare ground could touch something it isn't supposed to. The stranded conductor makes box makeup simple. To term to devices, use either ones with pressure plates, or use spade lugs. Use Wago 221s for splicing and tapping.

Excellent for wiring solar panels on motorhome. Flexibility compared to Romex is very helpful during install.
