I've done "electrical work" in a few (un-?)"developing" countries. It's a great experience, in being a chance to help those with less, and acquire some gratefulness for that which "we" have.
I think the biggest eye-opener, for me, is how much of the world has NO electrical grid, per-say. One fun experience was in eastern Peru, where circuit breakers are NOT for protecting circuit components! They are to ensure the generator does NOT stall. =) Also, being 40 miles from nowhere and several hundred form somewhere really get's you thinking on your feet!
A local church may have opportunities for such work. My father once did quite a bit of this type of work. It's taken him to 4 of the other 6 continents and in some of the most interesting places.
