If the load is 100 A ,the meter records correctly if the CT ratio is 100/5 as the meter gets 5A current . If the CT ratio is 600/5 the current in the meter will be 5/6 A for the same load current . Hence to get the correct reading ,multiply by 6.

On monitor it is written that current rating is 2.2 Amps. Is it a monitor current drawing capacity or CPU & monitor. If it is only monitor rating, what will be the rating of only CPU and what will be the power consumption rating of PC, Monitor & Scanner? In net, I learnt that computer consumes only 200-300W while running. With the current rating of 2.2 Amps, how it could be 200-300Watts. Please explain?
