How far can I run wires to CTs?
Setra CTs come with length of 15 feet and the Rogowski coils come with lengths of 6 feet. Additional leads can be extended for 100 feet using an approved wire. The Rogo is qualified for up to 100 meters. The extension wire must be 18AWG twisted pair wire for the CT. The extension wire for Rogo is 22AWG shielded twisted pair wire and the shields must be connected.
