I bought a GFCI extension cord a few months back. It's about 2-3 foot
long with a triple plug on the end and the GFCI works mounted in the
middle of th cord's length. Anyway, that stuff may not have anything
to do with my question, at least you know what I'm talking about....
I ran a heavy duty extension cord (about 40 feet long) from a standard
receptacle in my basement, through a window to the driveway and then
plugged the short GFCI cord into that, and then plugged my circular
saw into that. A friend who was going to be doing most of the cutting
(who is also a union electrician) saw this setup and told me I needed
to move the short GFCI cord so it was plugged into the house
receptacle and then the heavy duty extension cord could be plugged
into it, otherwise, the GFCI would not work. I told him I thought he
was wrong, but since he was doing the cutting (free labor, I might
add)I would hook it up any way that made him happy.
So now I am just curious, does this make sense? I know I've seen
these devices hooked up on jobsites at the end of a long extension
cord, just like I had it. And also, I would think if this were true,
it would have a big bold warning printed on it saying so.
What do you guys think?
