4 wire to 3 wire 240v adapter cable?
I need a 240v 20 amp outlet for an induction cooktop.
I've already got 50' of 4-wire 10-gauge cable as my original plan called for a simple/standard 4 prong dyer outlet.
Is it OK to just install the 30 amp 4-wire dryer outlet and build an "adapter cord" to power the induction cooker?
My thinking is a 3-wire cable (hot hot ground) with the necessary 20amp 240v receptacle on one end, and then wire 3 of the 4 prongs of a dryer plug. The H-H-G prongs would be wired and the neutral prong would not, essentially just leaving the neutral isolated/unused in the dryer outlet.
Would this be ok?
I can go out and buy some 3-wire cable if necessary, I just thought it would be nice to use the cable I already have. Not to mention having the 30 amp 4 prong outlet already installed would be nice for flexibility down the road.
thanks for any help
