Electrical question

I've got a newly-built house (well, actually, it's 2/3 new, 1/3 existing) with new wiring from the panel in. It's got a 200 amp rating at the panel. But whenever the air conditioning comes on, the lights dim and power dips much more than I've ever seen in another house, even ones with lower amps and older wiring. Sometimes it's enough to shut down my computer or TV.The wire coming in from the pole is what was here when only the existing house was here. How likely is it that a problem like this is on the city's side of the breaker panel?Jim Beaver

How about 100mA (0.1A) for 3 seconds. At 16mA you may not be able to let go.

20ma under reasonably ordinary conditions is quite lethal. The question is how much of the current flow actually goes through your body (versus somewhere else) and how long it happens. Skin resistance, parallel paths, etc. etc. etc.

Under extra-ordinary conditions, MUCH lower currents can be lethal. In surgery, currents on the order of a few _microamps_ can be fatal.
