Delta table saw trips GFCI

The starting capacitor does not increase or decrease the amount of current flow, it does however cause a time shift in the flow from the hot to the neutral and the neutral to the hot. The time shift means that at a given time the current flow on the hot is different than the current flow on the neutral. A difference of current flow between the hot and neutral side is what causes the GFCI to trip.

Delta table saw trips GFCI

For troubleshooting purposes you could try running the saw from the GFCI through a #14 or #12 extension cord. This should reduce the startup surge somewhat.

For a 15A saw and a 5% voltage drop at 120v max lengths would be 75' and 125', respectively.
