He hasn't messed up -=- a nice job of describing what seems to the high tech boys as something as complicated as a doorbell circuit. The routing by which some sort of energy is converted to the juice in our wall plugs, the technology and the work schedules of ALL those in the industry has to be lived with to be appreciated. The miracle is that it is kept as dependable as it is, and that there are so few instances of property damage and injuries associated. And, really, most of this latter is traceable to the Do-It-Youself-ers and the lower levels of self-defined professionals. As in every other essential field, the really good people are hard to find, but end up being the cheapest. How do you find them? Good question. They work by referral. Only the people who can't get referral and repeat business need big advertising, so in general, the bigger the yellow pages ad the poorer the quality. (The extreme is the tradesman or professional with unlisted phone. It does happen.) One good caveat: Don't pay any mind to the UL label on electrical devices. Look for the CSA (SA in a broken circle = C). The Canadians are much more realistic in deciding what's safe to use than USA. Please note that many of the cheapie switches and receptacles at the hardware store LACK the CSA marking. This is a good indication that they'd be over priced if they were FREE. I don't like the idea of the d-i-y doing his own house wiring or repairs even with cookbook in hand. I've seen too many bad, and some VERY bad results. A competent hands-on engineer certainly should be able to do any wiring work. Experience and practical engineering skills are more important than being able to read the cookbook. But the general rule should be: If y ou have to ask, don't try to do it.
