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.

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.
