I have my whole shop on GFI, I don't trip any on startup.
GFI is specifically for ground fault.
So if you are tripping them, either the gfi is bad or you have a problem
with your end equipement / or wiring of the equipment.

Either way, I tend to go overboard with those things. I don't mind
the cost given their benefit.

Just as long as you don't have to reset the damned thing three times
a day eh?g

If that's happening, there's definitely something wrong. :-)

Like the start-up of a 1HP motor?

That would trip a circuit breaker. If there's a ground fault at startup
something's wrong.


Due to the inductance of the windings of larger motors there is a
slight delay in the current flow between the hot and neutral leads.
This delay can cause a false trip of a GFCI.
