Oh boy! What did I do! I was just trying to make up
an
example of
dumb-ass electricians! At least this thread does relate to
Classic Computer

Well, a common problem I've seen three or four times personally is
to wire the neutral and earth swapped. This causes all manner of
trouble for UPS systems. They don't like it at all. :)
I've also seen wires taped together with incredibly
not-good-at-insulating masking tape, causing a high-resistance
(if you're very, very lucky) short.
Last one of those I found was when I went to change a light bulb,
and wondered why the ceiling felt all tingly. Joking aside, I'm
lucky the ceiling tile was between me and the wires.

I like that old Chrysler 300M commercial where the "right stuff"
1960's engineer puts his hand on the car, looks into the camera
and says "I still get a tingle every time I open the hood.".
Bzzzzzt. Paging Quality Control.

Watch out for semiconducting tape. I had one electrician working for
me, who wrapped all of the splices on a entire job with leftover
semiconducting tape. When we megged the leads, every one showed a
direct short to ground. The guy had over 20 years experience, but was
in over his head on that one.

^_^ By the time I've called for a final, the place has gotten a 200%
walkthru. I hit top & bottom of every recpt with the GFI tester, Just To Be
On The Safe Side. One time the inspector caught me napping. (I told my
helper to check 'em all, and he missed one.) It also helps to break in the
recpt. I've had some be almost impossible to insert a plug into.

I've seen plastic drywall anchors, duct tape, scotch tape, and bare. In
that order. In the same room. Some mananger needed to be fired!

On a similar and still on topic note, if you're working on the electrical
system in an older home (fusebox or knob & tube), watch out as the neutral
was oftentimes switched, instead of the hot! I laid my arm across the water
pipe four times before I figured it out!
