Answer / cnu

Please be specific in asking your question.

max load in the sense, the max load is defined to a
particular cable that is operating at a particular voltage.

and max voltage from earth to phase means...... how can you
decide that.

a 3-ph 415V supply has a earth to phase volate of 230V,
which is the one we have in our house.

Same way a 11KV line has an earth to phase violtage of
6.3kV. and so on we go upto 800KV.

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?
