The electric power supply circuit is normally taken from a single phase of a three-phase system and a ground wire.
In this setting, that is in a single-phase connection, the flow of electricity is said to be via a single conductor but in a three-phase connection, it is made up of three separate conductors.
Therefore, Based on the above, The electric power supply circuit is normally taken from a single phase of a three-phase system and a ground wire.
