A buddy I work with sent me these photos of an old skill saw that shows a grounding conductor/cord configuration I've never seen before on a power tool. Do you have any idea when the "3rd wire" came into play. Also, we read that these types of cords and grounding configuration is a "death trap". Have you heard this and why?
Appreciate your feedback.
