“I don't know where you got this information,.......”. Hi Matt, info comes from Blue Sea Systems wire size chart which takes into account both engine room vs non-engine room temps and bi-directional wire run length for a given voltage drop. My post, like many others, was designed to urge the OP not to use that wire in his GMC. He recently said he would not.
