Which options do you need?
- Surge protection adds a Type 2 surge protection device to limit transient overvoltages.
- kWh metering records energy used by the connected circuit.
- Load balancing adds load management. Check how the selected unit operates with your charger before ordering.
Choose the base unit, surge protection only, surge plus metering, surge plus load balancing, or all three options. Compare the configurations and open your exact model.
For a location exposed to water, compare the plastic IP65 range.
Before ordering
Ask your installer to check the exact WCED model against the charger instructions and installation design, including the earthing arrangement and required residual-current and DC leakage protection.
Delivery
We normally dispatch WCED orders the same day for next-day delivery, subject to availability and checkout delivery options.
How the load-management option works
On EcoHarmony’s single-phase PME units with load balancing selected, load management cuts power to the charger when the property load reaches the configured limit. When the property load reduces sufficiently, the unit automatically reconnects the supply. The charger then restarts; the charging session should resume automatically, depending on the charger model and its settings. This is supply interruption and reconnection, rather than continuous adjustment of the charging current.
What is included with the selected options?
A CT clamp is included when load balancing is selected. It is not required for the other configurations. A kWh meter is fitted when the metering option is selected. Check the selected variant and any stated higher-specification substitution before ordering.
Supply and operating details confirmed by EcoHarmony, 2 November 2026. Meter certification, communications features and accessory specifications must be checked for the exact supplied model.
Three common ordering mistakes to avoid
From EcoHarmony’s customer enquiries, the common mistakes are choosing the wrong protection for the charger, the wrong size or rating, and the wrong IP rating.
- Protection: identify the exact charger model and what it already includes, then match the installer’s required PEN, residual-current, overcurrent and surge protection.
- Size and rating: confirm the specified current rating, phase arrangement and circuit count, as well as enclosure dimensions and available mounting space. A higher amp rating is not an automatic upgrade.
- IP rating: match the enclosure to its location and exposure. An indoor unit must not be assumed suitable outdoors because it is under cover.
