The amp rating doesn't change with strand differences. That is what I was trying to tell you the other day. You are reading the table you posted wrong. Cores on that table is complete seperate covered wires inside another coating, not strands. That table is talking about home wiring, also called romex. And finer strands are better for vibration. I have been an electrician for 15 years so I'm not the brightest guy but I know a little about electricity. And Kellys stuff is really fine strand so you endorsing it and at the same time saying fine strand is bad is really confusing. I have Kellys battery cables and they are awesome.
The amp rating they give for AWG size is almost invariably for a solid core wire. I haven't looked at every table available. Maybe I used the wrong table?
Kellys cables seem oversize so any AMP rating lost in strand size (or not) is irrelevant.
The original poster seemed to want to make his own. What I offered was opinion, along with about 50 years experience in machinery and wiring machinery.
Kelly uses heat shrink on his cable ends, I believe, this is the point where very fine cable strands tend to fray. Kellys cables are over sized so heat is unlikely to be an issue. Corrosion over decades might be an issue.
Most drums of cable are labeled, AWG size, a wire type code, a strand configuration code, a DIN code, ASE code, mm squared size and if you are lucky an AMP rating, sheath temperature range (usually another code). And even the AMP rating isn't standard, maybe ten years ago they lowered it, almost across the board, by nearly thirty percent.
The amp rating doesn't change with strand differences.
If what you are saying is accurate, why all different kinds of cable?
All I was trying to do was make a point that rating cable Amperage by AWG size charts isn't always accurate and buying cable just by AWG size isn't necessarily good for a particular application. If I used faulty information trying to make my point I apologize.
The topic wasn't sharp shooting me or Kellys cables (like I said they work and they last) (it is what it is, rarely what somebody says it is and almost never what somebody says it should be). The topic sat there with zero replies for days. I was trying to be helpful, You never gave any advice except that my advice was wrong. I can't see how that was helping the poster at all.
OK I'm wrong, so what, what advice do have to give, besides not listening to my advice?
The only time IMO that oversized cables are going to help the starter much is at initial spin up, The battery to block ground carries more Amps generally.
And lastly, I tend to double cables, instead of pulling them and up sizing, whenever possible anyway. The reason is simple, redundancy works. The battery I have in my XJ has four poles.
