the old meter had a coil n wud spin faster or slower depending on the amount of current u used, dat was d turning disc u wud see, n dat disc wud turn a series of numbers , these nos wud represent d amot of units used and inturn ttec wud do deh calculation ( the previous numba minus d new value) a multiply buy d period of time which is every 2 months, and den dey wud come up with a kWh value den dey wud multiply d kWh by uh rate (residental or commerical) and dis is how dey use to com up wit d amt u hve to pay, dats why dey say it was an estimate, cus dey use to estimate d value on meter cus dey never use to come n check it all d time...
dats why wen these new meters now come on d system ppl taught dey bill was wrng or too high, cus dey using d same amt of tings in their house, but infact its more accurate to the true amt of power u using in uh hme. ppl jus accustom payin less cus d old meters/system were less efficient and accurate.
as for d size of the wires used, there is d electrical code in trinidad dat specifys wat size to use for wat appliance n equiptment, dey dse rate d wire size according to the current consumption.
for lights its 1.5mm n normal everyday use plug its 2,5mm...whereas for air cond, it wud vary wit d size of d unit, a 12000 btu dse normally use 4.0mm wit a 30A breaker.
