Specifically, kitchen receptacles in homes are wired with 2 phases and a neutral: this allows 2 breakers (ganged) to feed a single duplex receptacle so that plugging a toaster and an electric frying pan into the top and bottom of a single receptacle does not trip a breaker. The local inspectors test for this by measuring the voltage between the 2 hot terminals on each kitchen receptacle: if they do NOT measure 230Vac, it fails the test. Industrial wiring shares the neutral between the 3 phases for most 120V outlets and for area lighting. You tend to find dedicated neutrals only on special outlets such as those dedicated for computers and such. dwayne Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 17 years of Engineering Innovation (1984 - 2001) * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Do NOT send unsolicited commercial email to this email address.
