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.

In the early days of GFCI, even nearby electrical storms were
responsible for nuisance GFCI trips.

The advent of "hospital grade" GFCI devices advanced the quality of the
devices to where that is no longer the problem it once was, although it
still happens and is always something to consider.
