Description

Taps phase a of a three-phase plug as a single-phase pin, so single-phase blocks can connect to it. The other phases carry no current through this block.

Example

Three-phase loads A 10 V three-phase supply into a resistive star load, a series R–L star load, and a capacitor bank in delta.
