Last night, I purchased a new Delta 50-760 through an Amazon price match from a local dealer. I brought it home, assembled it, and plugged it into the fused, dedicated 20A circuit I use for my TS with identical motor ratings (1.5 HP, 15A @120V). When I turned it on, the motor started to spin, then blew the fuse in the circuit. Since I had extra fuses, I decided to try it a second time. Same thing happened. Initially, I was thinking I needed to convert it to 240V (which I intend to do in the future), but noticed that the two blown fuses had their windows blackened. The fuse package said that indicates a short circuit instead of a overloaded circuit. Was this simply an overload, or could there be a problem with the DC motor?

Any assistance would be greatly appreciated!
