I’m not sure what happened. I plugged in my contractor saw, made a few cuts with no problem. When I went to unplug it I was these pics.

The wall side has no marks or anything. There was no bogging or anything that would indicate a power drain. I didn’t see a flash (the plug was behind the saw and on the ground though) nor did I smell anything.

Any ideas? And more importantly, what do I do know?

Put a new plug on your saw (making sure to get the right amperage rating) and throw away the extension cord/multi-tap.

Pretty much agree with Steve. What happened is the extension cord connection inside the orange plug more than likely became loose, causing the arc inside the extension cord. 120VAC can jump with the right amperage, and your saw was drawing it, so the arc happened.
You need to obviously replace the plug on the saw, and I would buy a heavy duty extension cord with only one plug on it.

I don’t believe this was a short either. Like Tennessee, I suspect a loose connection inside the orange extension cord. I don’t like those cheap damned extension cords – I’ve had way too many failures like this. They get “tired” after a lot of use and just don’t maintain enough pressure to guarantee a good contact. Also, that cheap molded plug on your saw doesn’t look like it is rated for heavy current. Is that what came with the saw originally?

Thanks guys. I’ll chuck the orange cord and put a new plug on my Saw.

Yup, just wore out and got too loose. Happens all the time ;-)
