THANKS TO ALL YOU THAT HELP US.

PS. Can t say if we are a couple of diy , we work in the electrical field every day and know we have a long way before being electricians. We did try to get it right so to be safe and not have to redo it after an inspection. With all the help we got here we should pass. Thanks.

You could use #3 Cu if the panel terminations are rated for 75 degrees C. Otherwise you need #2 Cu.

60 degree column. It needs 1/0 AL. Or you could install a 90a circuit and use something smaller.

so #1 al should be fine for 100 amp??

Which they will be for new equipment, or even equipment about 30 years old likely will be.

so why even put in 110.14 (c)(1)(a) ?

If equipment is not marked then the values in that section are what you use. Most breakers, motor starters, fused disconnects and other similar gear for the past 30 years or so have been marked 75C for sizes that otherwise would have to default to 60C. Equipment older then that is seldom marked at all - default to 110.14
