Does the GFCI trip? Sounds odd, since most GFCIs are set to trip the circuit at 0.06 amps or something like that....

That’s definitely not a good sign then, you’ve got something going wrong there. The whole point of the E-Stop is to let a little bit of current out of the system and into ground, which the GFCI sees as a current lost and trips.

Do you have a wiring diagram that you used?

Well that is a little better, but the GFCI shouldn’t let more than 1 amp escape the circuit through ground. Think if your body was that conveyance of electricity, you could die.

This question may sound stupid, but are you sure you have a 1 amp fuse and not a 1 mA (milli-amp) fuse?

Is there a resister in series with the fuse? You need one to limit the current.

You should have hot-resistor-fuse-estop switch-ground. Any order works between hot and ground.

The fuse is redundant and potentially unsafe for a safety circuit IMO. You may have trouble with your GFCI breaker if it is tripping but still blowing a 1A fuse. The GFCI should trip long before you should be able to blow the fuse.
