Breaker size?

[Delw]

vf2ss with 4th axis.

My salesmen says a 100 amp breaker, thats #1 wire. is that correct on the breaker size?

After owning probally 10 + machines and installing over 50 before I started my own place I never used more than a 75 amp breaker and on small machines 40-20 and under with 4ths and 5ths never over a 50amp.

so are they trying to figure out that I have at least a 100 amp panel or do I really need a 100 amp breaker to the haas disconect box?

I searched the forum and couldnt find any info looking under breaker.

He is out to lunch, 50 is enough and in fact you can run a VF2 on a 40 amp breaker but that is getting close.

I just found the tech page on the haas website, there pretty serious, i think its an over kill but ok. I had my chart wrong ( the one in my head ) about the #1 wire its actually #3 for up to 100 amps but #3 isnt common so #2 should be used, however #4 goes to 95 amps on thhn.

for a min I was thinking there goes my Ac in the shop this summer, that would suck big time.

Out to a martini lunch for sure. I have seen a 40 amp work for years.
