Earthing CAT6 SWA cable connecting EVSE.

Sparkingchip

Armoured External Cat6 UTP Solid Cable (Price Per Metre) | Cat6 Cable (cablemonkey.co.uk)

When running CAT6 SWA to Electric Vehicle Supply Equipment to provide an internet connect to allow the equipment to be activated remotely using an App or by the electric supplier if the consumer has signed up for a tariff that allows the electric supplier to select the precise charging times should the SWA armour always be earthed at one end only or should it mirror the connection of the CPC or armour of the EVSE supply circuit?

    Salespeople like to give features a fancy name to upsell products, so it’s important for installers not to get lost in a world full of gobbledygook. 

    Zappi has a feature called “esense” all it is is a terminal in the EVSE allowing it to be hardwired with a 1 mm cable to the off-peak contactor of a smart or dumb meter switching the boost on in the EVSE when an off-peak tariff is available, allowing the meter to take control of the charging period utter regardless of it being smart or dumb.

    Now that seems straightforward.

    eSense
    The eSense input can be used for two function:
    1. It can be configured to automatically activate a Boost during ECO or ECO+ charging, whenever economy tariff electricity is available. The eSense input must be wired to a circuit which is live or an external volt free contact which closes during the economy tariff times for this to function.
    2. It can be used to limit the zappi output or stop the charge – for instance, using an external contact from a smart meter or control box provided by the Distribution Company who may require the ability to control the power being used to charge an EV if their network is overloaded
