You need to ensure the CT sensor clamps are installed on the correct cable to receive the correct readings

These options are a guide only and you should consult your electrician to ensure the location of the CT sensors is correct

Pull the clip on the CT clamp and open it

Place the cable in the CT and close it. Make sure the clip on the CT clicks closed and locks in place

Drill a hole in the side or bottom of the switchboard. It should be large enough to accommodate all the CT cables you are installing plus a rubber grommet

Install a suitable rubber grommet into the hole (Not supplied)

Pass the connectors through the hole

If the switchboard is located outdoors, ensure the penetration into the switchboard is waterproof
