Key Takeaways
- A dedicated circuit for the charger, not a shared socket.
- A suitable protection breaker (about 40 A for 7 kW) with RCD protection and proper earthing.
- Check household load and panel capacity before installing.
- An 11 kW charger needs a three-phase supply.
Before buying a charger, make sure your home is ready for it. The key requirements:
1. A dedicated circuit
A charger is a high continuous load for hours, so it needs its own circuit straight from the panel with a correctly sized cable, not a socket shared with other appliances.
2. Protection breaker, RCD and earthing
A breaker of about 40 A is typical for a 7 kW charger and 50-60 A for 11 kW, with RCD protection and proper earthing to protect people from leakage current.
3. Panel capacity and household load
If the panel is full or the household load is high, you may need a panel upgrade or a load increase request to the utility. We measure the actual load and explain your options.
4. Supply type
A single-phase supply usually handles a 7 kW charger. An 11 kW charger needs three-phase supply and a car that supports that rate.
Costs are broken down in the installation cost guide. To book: load check and panel upgrade in Khamis Mushait.
Frequently Asked Questions
Do I need a dedicated circuit for an EV charger?
Yes. A dedicated circuit with a protection breaker, RCD and earthing is recommended because a charger is a high, continuous load.
