At where I used to work, (which was bought by a cal company) they improved everything but the installed elec dist sys.... R. the (alleged) leading electrician had the following theory.... "I can be out of electricity, I still have open slots in the breaker box"....lol Push came to shove when they tried to install a new "sofisticated electronic testing device" It wanted 480V. (big period) that section of the complex, had been running on 430volts fer the last year or so (due to all the additional equipment installed) The installation tech said if you can't supply me with 480v, than I will have to leave and take the warranty with me", some one called the yahoo from cal who was our new boss, he wanted us to change the taps on the xfmr. I refused citing "just what do you think will happen if they shut down the power users portions of this bldg??
it finally woke them up to upgrading the txu tranformer and switchgear
