Superior electrical cable with copper electrical wire for residential electrical wiring projects. 12 AWG Romex SIMpull NMD90 with Freeze Flex includes 2 copper conductors and one ground wire. Use it for electrical wiring of A/C window units, workshop outlets and kitchen counter receptacles. Romex SIMpull features Southwires NoLube SIM technology which has revolutionized the way wire is pulled into conduit without any pulling lubricant, saving contractors both time and money. Romex SIMpull NMD90 electrical cable pulls 50% easier, is tear resistant, reduces burn-thru and strips easier. Freeze Flex gives you more pliability, easier stripping and added crack-resistance in cold weather. Southwire Romex SIMpull NMD90 is manufactured using annealed (soft) copper conductors. Compressed stranding for the stranded conductors. 90°C rated PVC insulation with a nylon jacket for the individual conductors; a PVC jacket surrounds the overall construction. Minimum recommended installation temperature is minus 25°C for two-conductor cables and minus 10°C for three-conductor cables. Should be properly stored above 0°C for 24 hours prior to installation. The maximum allowable conductor temperature is 90°C. Maximum voltage rating for all intended applications is 300V.
