- Come on, now, Chris. Most houses built since the mid-fifties (at least)
- have had circuit breakers, not fuses. Houses with fuses have electrical
- systems that are at least 40 years old, perhaps much older. Therefore,
- your conclusion is faulty, since the electrical code almost invariably
- grandfathers in installations that were correct at the time they were
- made. The only way the fuse box would be in gross violation of the
- code would be if it had been so at the time it was installed.

- This is more to the point. Any time you work on the electrical system,
- use a meter to test every wire. I once worked for the local electric
- utility (PG&E) at one of their largest power plants, and had to run
- a conductivity test during a performance test on a 750MW unit. I was
- located on a steel grating about 30' off the ground, directly below the
- boiler. Not only is it fairly noisy, but everything seems to resonate
- with a 60 cycle hum, being close to the turbine and the transformers
- that feed into the power grid. I plugged in the conductivity meter,
- then pushed the rubber-tired cart which had the meter on it, and began
- oscillating at 60 cycles myself. It turns out that an adaptor I was
- using from double prong to twistlock was miswired! As it came from the
- factory, one of the hot legs was switched with ground. That experience
- sure made a believer out of me! Fortunately I was wearing rubber-soled
- shoes.
-
- So, don't trust the labels.
