/diy/ - Do It Yourself

I made a splitter plug to turn a nema 14-20 into 2 120v outlets by taking 2 extension cords and chopping off the male ends and putting them in a plug. I used pic related as the diagram, both greens to ground, both whites to neutral, and each black to their own hot. I'm getting 108v at each end (220v service divided by 2 minus 50 feet of loss) however I can't get any current from it, I've tried my grinder and drill and neither work. what the fuck, over?
