Not really. I'm in the field, and I never do hard core electrical work. If I need to fix any hardware, parts usually get replaced, not repaired. It can be handy, though if you are interested in that sort of thing. One of the guys I work with was an electrician, and he has done a lot of work wiring up rack sized UPSs, and running power outlets to comm closets. It lets us get stuff done faster, since we don't have to wait around for the electricians to show up. Other than that, though, you wouldn't really do a lot of electrical stuff.
