The Stovebolt Site Forums The Shop Area The Electrical Bay Is "crosslinked" wire (i.e. SXL) necessary?

As Bill says, pvc is adequate. The wires have a safety factor built into the heat spec. 300 deg under the hood? I'm not sure that is correct. Recent studies using thermocouples show engine compartment "center of hood" temps at below 100 deg. High temps were recorded at thermocouples mounted on catalytic converter and exhaust manifold (direct contact.) Lots and lots of pvc wires under hoods of old trucks across America, Canada and beyond, no melting yet. No wire will withstand direct contact with an exhaust manifold or pipes... or a catalytic converter which I'm sure we all have.? Not.
