How many watts does a 2hp electric motor draw.

Yes noodle but you are running off a tranny down the road with plenty of back up, not a petrol motor with very limited horse power. It's not the size of the protection it's the power produced that effects start up.

Um no

Think you'll find Noodle is right here. It's the maximum dude

Have you never heard a genie when load is put on it!
The load is applied, the gennie slows, the load gets less as soon as the motor begins to rotate the govenor on the genie feeds the genie more fuel untill it runs happily i have run a 2.4kw 9 inch grinder off a 3kva genie for years

Yup and while it's going thru the wind up stage you are stressing the electrical winding. You effectively turn it into a small heater for a while. With a grinder also you have very little load on start up. Try starting it with the disc against steel to start with as a compressor is on some load on start up. That is a given.

I would imagine that the soft-start grinders are a bit kinder on the generators than traditional types. The soft start ones accelerate over about 2 seconds instead of what could be less than half a second for the normal type.

this site has some good graphs showing respective motor start currents with a DOL (Direct on line, just plug in in) and soft starter:

This is not a soft start grinder, we are talking about one of the cheap nasty chineese compressors arn't we! not a big belt driven compressor, big difference between the two

You will need a 5KVA generator petrol driven or a 3.5KVA if diesel driven
