Does anyone know why in 310.15B the derating stops at 50F or less ? We just did some large conduit runs in a cold storage cooler (-10F) and was thinking about what the derating should be at that temperature. I'm not sure if it would still be 1.2 or not ?? any thoughts on this or other very cold wiring derating applications ? Is there a chance of a new column or two at very low temps ?
