Zerp 3 Purchased to prevent voltage drop when using an orbital polisher. The specs on the wire say it is of a sufficient gauge so it should be okay. Looks like quality wire.NOTE: Used the cord for the first time today. I plugged in my leaf blower, used it for about 20 mins to blow the water off my car after washing it, and when I finished one of the covers on the connections had broken off. My rating went from 5 stars to 3 stars.
