I have a Delta 36-L31 3 HP, 1 phase 230 Volt saw, and have it located in the center of my shop - about 6 ft from the nearest elec outlet. The stock power cord is a bit too short - about 8ft, so I am looking to buy either an extension cord or a replacement cord that is 14ft or so. The current cord is 14/3 - any idea of where I can buy such a cord?
