Overview #
Power coming into the property is monitored by a Current Transformer (CT) that clamps around the property’s incoming power cable and is then connected to the charge point.
- The CT has a cable allowing it to be connected to the charge point.
- Additional cable may be added to the CT cable but to maintain a good signal, it is recommended that cables extensions are kept as short as possible.
How to Connect the Wire #

Connect the CT to the Property #
- The CT clamp should be positioned around the phase cable between the Meter and the Consumer Unit.
- The arrow shown on the CT clamp must point in the direction of electrical flow TOWARD the consumer unit.
• Alternatively, if required, the CT clamp may be positioned on the Neutral cable leaving the Consumer Unit. The arrow on the CT clamp must point in the direction of electrical flow AWAY from the consumer unit.
