This cable carries multiple ratings in one wire:UL MTW Machine Tool WireUL1426 BC5-W2 Boat Cable ABYC and USCG Approved for use on boatsUL THW Building Wire Meeting NEC Code for building wireUL AWM Styles 1232/1283/1337/10070 Rated 600VUL AWM Style 10269 Rated 1000VUL VW-1 Flame RatingRoHS CompliantSAE J1127 SGT Automotive Battery CablePVC Jacket is Very Resistant to Oil, Water, Acid, Gas, Tears and AbrasionsThe Jacket Insulation Meets UL VW1 Flame Resistance RatingAnnealed Pure Electrolytic Copper with Class K (Type III) Rope Lay for flexibilityFULL AWG Copper ContentMADE IN THE USA ABOUT THE WIRE USED: This multi-rated battery cable is specially designed to meet the demands of various environments while staying flexible. Full AWG sized OFC copper conductor made from pure annealed electrolytic copper, will you get maximum power. The PVC jacket compound is specially formulated to resist chemicals, water, abrasions, oil, sunlight and is rated water resistant 75C Wet and 105C Dry (BC5-W2). This cable is rated up to 1000 Volts as AWM 10269 and 600V as the other wire types. Suitable for use in automotive applications, solar battery bank wiring, power inverter battery cables, marine battery cables, NEC Code wiring situations and many other applications calling for a durable yet flexible battery cable. The battery cables meet the requirements of SAE J1127 Type SGT as well as UL1426 BC5-W2 making them ABYC and US Coast Guard approved for boat and marine use. BENEFITS OVER WELDING CABLE:Full AWG Size OFC Copper ConductorUL Listed - Quality Strictly ControlledSuperior Oil Resistance of PVC where EPDM on many welding cables is a poor insulator against oilSAE Rated for Automotive and Marine UsesUL Listed as water resistantMeets NEC Code requirements BENEFITS OVER CCA POWER WIRE:Our cable is Copper...REAL COPPER but watch out for other "CCA Cable" as CCA Means Copper Clad Aluminum so you'd be using Aluminum which is a poor conductor compared to this pure copper cable! You have to use larger sizes of aluminum CCA cable, approximately 2 sizes larger to get close to the same power delivery as real copper cable! If you care about maximum power use our cable!
