Topic: Imperial & Metric
2 yrs ago i did an electrical installation on an Asphalt Plant in Freeport Airport on Grand Bahama Island, what prompted me to say this the fact that you are still in imperial in the U.S.
when i arrived on site i needed various types of cable and heavy duty switch boxes so i jumped into the car and off i went to the wholesalers when i got in they did not understand a word i was talking about, off course i was in metric ?, i was rabbiting on about 150mm 4 core cable, switch boxes with 25mm entries and 32mm i went everywhere and i could not get any sense.
I told the site manager (a chinese chap with the chinese company) that i couldnt get this material i needed so he said i know a man in America that may be able to help me, this chap rang me wanting to know what i wanted, again i was off in metric he said whoooo hang on i dont understand a word of all that i will come over to see what you want.
this chap arrived about a week later i showed him what i wanted, but instead of telling him the cable sizes i needed he wanted to know the voltage and current required, and how much in yards or feet, so i told him i wanted 600volt 600amp cable with a 600amp changeover switch and he went away happy, about a week later everything arrived in a big box and i done the job.
we have been in metric along time now in the uk, and off course all electrical materials are all in metric, but we dont think in imperial anymore, lbs & ounces = Kilo grams, lbs per sq feet = Bar
1 Bar = 14lbs, anyway do you think some day the U.S. may change to metric.
