- Avoid creating large loops of CT wiring, and limit the amount of wire that needs to be untwisted.
- Twist-on wire connectors (wire nuts) can be used, but ensure they are rated appropriately for the installation and specifically for the stranded wires. Ensure the appropriate size is used to create a solid mating between the sets of wire.
- Butt splice and other styles of crimp connections can work well when used in conjunction with the correct ratcheting crimping tool is used.
- The most reliable connection is a soldered connection with heat shrink. Consider solder seal butt splices (example) in conjunction with a crimp tool and hot air gun.
- Always perform a tug test on your wire landings to ensure the meter can accurately register the energy usage across the wiring.
