I don’t think the 4hp is going to tell you much besides something to search for
to look up other comparable shop vacs. 1hp is 745.7 watts, so 4hp is 2982.8
watts. 2982.8W/120V = 24.86A which would be crazy. I searched for a 4hp shop
vac and found a porter cable one that advertises 960W. 960W/120V=8A which seems
more reasonable. I’d recommend measuring it!
I intend to John. Thanks.
I was a bit chagrined that just changing the hose, mainly because the
old one got clogged with a ball of swarf and wasn't letting a whole lot
of vacuum thru, to discover the new hose worked great but the increased
air flow was way too much for the motor.
Right now I'm waiting on the printer.

I blew up old bucket-vac by putting a larger diameter hose on the intake.
This raised the air flow and the amps it drew, and apparently tripped a one
time thermal fuse about 9 minutes into a 12 minute job.
So now I am adapting by 3d printing, all the plumbing to use a 5 gallon
wet-r-dry as a vacuum src, but this puppy came with a different motor claim, 4
hp peak, and no amperage data where the decade + older bucket-vac claimed 6.5
amps and IIRC 2.5 hp.
This one claims 4 hp peak but that is likely only for short term use and this
may run for a day at a time, possibly even longer. Sucking up swarf or saw dust
as my go704 works.
I have no clue how to translate 4hp into the amps I'd see on an Amprobe which
would equal 4hp on a 125 volt circuit. What I intend to do is restrict the size
of the intake nozzle until the amps drop to whatever corresponds to 3.5 hp.
These things are $50 a pop at Wallies, and I'd like to run it at something
resembling a CCS rating.
Does anyone have a clue how to translate that 4hp into amperage for the motor?
Thanks all.
Cheers, Gene Heskett.
