Booster Cables: Gauge vs Length?
Permalink  
 


I bought a spool of copper #2 AWG booster cable wire at an auction the other day and I was wondering if there's a "rule of thumb" for the length of cable based on the wire gauge?

No matter how long you make them, They will be 2 inches too short when you need them most....biggrinbiggrinbiggrin

Seriously #2 gauge will boost most anything you will ever see short of a tractor trailer even if 25 Ft long.

And if you get in a tight spot, you can use a short cable for the ground, from chassis to chassis. That way you have use of the other two, for the positives. At one time I've even gone bumper to bumper for the ground - steel only of course.

Make sure you use REALLY good clamps with wire that size, not those cheap little copper units.

Mine are 30' feet #4 and clamps are 500amp steel. We call them the Hydro Lines.
