DIY GFCI switch with CT

hlf0319 · Dec 10, 2021

Hi,
I got an old electrical box (used for pool equipments). The GFCI switch in it broke. It's made by Leviton but no longer in production. Can someone give me idea on how to DIY such GFCI?

The GFCI is marked as 125V 60HZ 20A, the front is traditional, but the back has a current transformer core. When things are plugged, the 120V wires are plugged in the front leads and three wires go through the core (0V, 120V, 240V).

Any help is appreciated. Thanks.

It appears that you have the wrong GFCI receptacle.
