Thanks for any advice.
Which end of the cord are you proposing to use the L6-30 or both? Is it the exact cord linked in the beginning of the thread?
Why do you want to do this? It already has 14-30s, why not use L14-30?
A 110/220 gfi monitors all currents in the three current carrying conductors and if the sum of the currents are non-zero it trips. Since this particular gfci was/is designed for a 110/220, the detection circuit inside the cord may need a neutral connection, back to the main panel, to operate correctly.
