4 INSTALLATION INSTRUCTIONS
4.5 Variations and Installation of Current Transformers
• Leviton split core CTs (Figure 9): The side with the white dot, H1, must face the
incoming LINE. White wire connects to X2 terminal, black wire connects to X1
terminal.
Installing split core CTs
1. Route CT wires through conduit if not already done.
2. Trim the wire to the appropriate length to avoid coils of excess wiring.
3. Strip wiring to approximately .300 inches.
4. Connect the CT leads to the appropriate meter as described above.
5. With power to the conductors turned off, place one CT around each
conductor, ensuring that the white dot is facing the line side.
Failure to install CTs in the correct orientation will lead to inaccurate meter
readings. Figure 10 through Figure 12 show wiring diagrams for the various
voltage configurations.
