This makes it sound as if the 1 amp fuse and resistors are between the E-Stop and the ground. But the wiring diagram on the first page show the fuse and resistors between the load and the E-Stop button. Can someone confirm for me which way it should be? Thanks in advance.
Hi - The diagram does show the resistors before e-stop button, but I did wire in the resistors after the button. I did not use the 1 amp fuse, after having a discussion it was determined that the fuse was not needed, since if the fuse failed then the e-stop circuit would fail. Ideally I'd say to have the resistors before the e-stop button, but the circuit will work fine if you place them after. The point of the resistors is to limit the load that gets sent to the GFCI breaker when the e-stop button is pushed. Only a small current is needed to trip the GFCI. The resistors will limit the load if they are before or after the button.
EDIT: If you do have the resistors before the e-stop button, be sure to shield the soldered connections well, since they will be carrying a load 100% of the time that the panel is powered up. If you have the resistors after the button, they should still be shielded well, but will only carry a load for a brief moment after the button is pushed and before the GFCI trips.
