Why we did not multiply by 3 because of the three phases?? And you can see the rules in the second picture if I am mistaken so when we use them

Expert Solution
Step 1

Condition no (01) 

If the value of the load in the question is given as power [ whatever Active power (P), Reactive power (Q), Apparent Power (S) and together with the power factor ]

So we will consider it as three phase Power only (not consider as per phase power) 

So there is no need to multiply it by 3
