Review: Very flexible and easy to route in an RV appication. - 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.
Review: Works good. - 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.
