Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 1):(15 A)
Concept:
The power rating
P = V I cos ϕ
where
V is the voltage
I is the current
Calculation:
P = 3 × 1000 W
V = 230 V
3 × 1000 = 230 × I
I =
= 13.043 A
The cable rating suitable for connecting a load of 3 kW to a single-phase supply of 230 V is 15 A
