Default Question on starter size

Hi,

The largest load will be a 10HP (+ 1HP feed motor) wide belt sander. It
will have a heavy starting load due to the inerta of the steel rolls. I
will also want to run a 3HP dust collector at the same time. The smallest
load will be 1.5HP. So everything from 1.5 to 14HP at one time.

For idlers I have a 15HP, a 10Hp, a 7.5, and a 5HPavailable. I believe
(hoping!!) that I can get away with 15HP of idler. Have max of 60amp 240
single phase supply but I am going to try with 50amp first (much less work).

Haven't decided whether a single 15HP would be the way to go or a 10/5
combo. (more complicated).

Thanks,
Glen

I agree with your post, but I want to note that size 3 starters are
very expensive, even used.


In this case Glen should probably make his choice based on what he
intends to run from the convertor. The size 2 should be fine for a 3 hp
Bridgeport (say) but could be inadequate for a bad ass welder like yours
:-).

By the way, I like your pics of the new phase convertor. I missed the
pictures when you first posted them, but just saw them now. Nice job.
