As stated earlier I am VERY against the 'suicide cable' but I am all for cam turnarounds. I keep a set myself.
Sometimes one is backwards, as stated above, or yada-yada-yada. And in reality most of the time around here there is a
disconnect switch without cam receptacles so an electrician is needed to
tie-in anyways. The cable is run, connected to the other end... Everything is checked, THEN the fuses are installed,
switch closed and thrown closed.
The contacts for cams are reasonably recessed for both male AND female, and it is not a single
connector anyways. Separate cable or '
wire' for each.
Cams should only energized after all connections are made. Most people are scared of them so they don't touch them, they are kept secure AND the people working with them know better than to touch them energized.
Personally I lock-out the
switch until everything is checked and ready for
power. So it's safe. Plus the inspector is generally okay with it, which makes me happy.
