EV Chargers & Your Home Supply đźŹ
An EV charger is a high demand device (32A) on your home’s supply, and it can run for a long time – potentially up to 12 hours! ⏳
UK Homes usually have a main fuse rated at 60A, 80A, or 100A.
With this in mind it is important to manage the load the charger is putting on your home supply.
Load Curtailment helps by:
🔍 Monitoring the load on your home supply
🔽 Reducing the charger’s power if you are close to the fuse limit
🔼 Increasing the power again when there’s capacity available
Load curtailment requires the External Current Transformer (CT) to be fitted.
Note: If the External Current Transformer (CT) is removed or disconnected, the charger will de-rate and charge at a slower rate of ~1.4kW (6A) to protect the main fuse.
