Let's get the terminology correct to start with.
The conductors that connect the load to the supply are LINES (or 'line conductors', NOT 'phases'! Which is why the voltages measured between them are called 'line voltages'.
PHASES are not conductors, but the connections, such as individual loads (or the windings of an alternator or transformer) between line conductors, or between a line conductor and the neutral.
So 'phase voltages' are measured between lines (in the case of a three-wire system) or between a line and a neutral (in the case of a four-wire system).
So we measure line voltages BETWEEN lines, and we measure phase voltages ACROSS phases.

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
