Measuring current in centre tapped supply

Former Community Member
Former Community Member

Hi all,

I am wanting to monitor the current to a 110V motor fed from a centre tapped transformer. Total current could be max of 16A, so a CT will be required. My question  is, how do I get the actual current used by the motor? Can I simply put 1 leg through the CT, set the meter to the correct ratio and that's me or am I missing something?

Cheers

    The the fact that the supply is from a center tapped transformer is not relevant. The connections to the motor should consist of two current carrying wires and probably a protective earth.

    Measure the current in either of the two current carrying wires.
