Not the same temperature rating. You need or want wire with a rating of 105C. Automotive can come in 65C as well, but that should not be used near the engine. Better just to use the higher temperature stuff every where.Maybe a stupid question but can you use typical commercial / residential wire (THHN/THW) for this or does it have to be like "automotive grade"? Just curious because I am an electrician and have this regularly available. I'm just not sure if the stranding would be the same too.
