4HP=2.9828 kW
I(A) = 1 kW × 1,000 / 120 V
I(A) = 1,000 W / 120
I(A) = 8.33 A
So, generating 1 kW of power at 120 volts will draw 8.33 amps of current.
After looking at this, I may never run my Shop Vac again.

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.
