wiring harness loom tubing heat specs

Okay, found some of this wiring harness loom tubing at Lowes. Their site didn't have the temperature specs so I called the company. The mentioned that the high temperature is 200 degrees F.

Would this be okay for wrapping the wiring harness from the stator wires to right behind the battery box?

The link to the product is

Thank you in advance,
Steven

As long as the plastic loom doesn`t touch the exhaust pipe or the goat`s belly, it should be fine.

Thanks Gordon. Picked up some from Lowe's tonight.

More important than the temp rating of the loom is the temp rating of the wire insulation. I gather from your other posts that you have rewired the stator / regulator wiring. What is the rating of the wire insulation? The current carrying capacity rating of any particular guage is primarily dependent in it's insulation temp rating (and allowable voltage drop). The same wire will have a higher current rating in "free air" than if it is bundled in or in a conduit.

Our charging system is rated at 24 A @ 14 VDC. Assuming equal current distribution among the 3 AC stator phases, that give you 8 A(RMS) per wire.

Bundling the wires in a loom will reduce the current rating of the wires unless you use a higher temp insulation for a given wire size.

Bottom line: the loom may be just fine, but may cause your wires to overheat depending on wire guage and insulation temp rating.

I should have remembered that sunpa.

I recall now, someone saying a long time ago that tying the stator wires together on his bike, was the cause of overheating them and burning one or two of the connectors off.

Thanks again for the input Sunpa. I need to check the insulation of the new 14 gauge wires I replaced the existing stator wires with. Will definitely individually wrap each stator wire with good electrical tape to avoid them passing heat to each other. Will most likely wrap them from the stator all the way to the R/R, just for an extra measure. Now, would I need to also rewrap the section of the wiring harness that I removed the previous wrapping with when I rewired the stator wires, or would the conduit work fine?

Just throwing this out there..I noticed when repairing my stator wires the previous owner had actually run the stator wires through a piece of conduit..put a few slight bends in it and uzed zip ties to secure it to the frame and believe it or not it looks good (its painted black so blends in) lol

Dang, I wish I would have thought of that before I removed the wiring harness insulation. I wonder, though, with just the stator wires running through the conduit, isn't it still possible they would produce enough heat to melt them together (if they were touching in the conduit that is).

I gotta say the copper does look pretty cool.

And I like the fact that it keeps the stator wires away from the wiring harness.
