Home EV Charger Installation, Step by Step

Installing a home charger is a straightforward job for a qualified electrician, but each step matters for safety and charging speed. Here is what a proper installation looks like.

1. Check the electrical panel

Most home chargers run on a dedicated 32 A or 40 A circuit, delivering 7.4 kW (single-phase) or 11 kW (three-phase). The board needs a free way for a dedicated breaker and enough spare capacity.

2. Choose the charger

• 7.4 kW single-phase wallbox — the most common choice.
• 11 kW three-phase wallbox — if your supply and car support it.
• Portable charger — useful as a backup, but slower.

3. Install a dedicated breaker

The charger must have its own circuit with appropriate protection (MCB plus RCD, or an RCBO). Never share the circuit with other appliances.

4. Run the cable

Use good-quality, outdoor-rated cable sized for the distance — typically 6 mm² or 10 mm². Keeping the run short reduces voltage drop and cost.

5. Mount the charger

Fix it to a solid wall near the parking bay, protected from direct sun and rain where possible.

6. Test

A proper commissioning test confirms that charging starts straight away, nothing overheats, and the breaker does not trip under full load.

Indicative cost

Simple installations are often quoted around AED 500–1,200 for labour and materials, rising to AED 1,500–3,000 where panel upgrades are needed. Always get a site-specific quote.

Safety rules

• Never charge through an extension lead.
• Always use a dedicated breaker.
• If in doubt, use a licensed electrician.
