EV Charger Load Certificate & Load Increase Study in UAE

EV Charger Load Certificate and Load Increase Study in UAE

Installing an EV charger is not only about choosing a wallbox. The electrical supply must also support the new load safely.

This is especially important for 22kW chargers, multiple charging points, dealerships, workshops, fleets and commercial DC chargers.

MEV Charger provides site inspection, load calculation and technical reporting for EV charger projects across the UAE.

What Is an EV Charger Load Certificate?

Customers often use the term “load certificate.” The more accurate term is an electrical load assessment report or load increase study.

The report can show:

• Proposed charger load
• Number of charging points
• Required current
• Available electrical capacity
• Main panel condition
• Cable and breaker suitability
• Whether a load increase may be required

When Is a Load Study Recommended?

• Electrical capacity is unknown
• An 11kW or 22kW charger is planned
• More than one charger will be installed
• The main breaker is heavily loaded
• Breakers trip repeatedly
• A commercial or fleet project is planned
• The consultant requests a load schedule
• The authority requests drawings or load details

What We Check

Main Distribution Board

Main breaker, spare ways, busbar, connected loads and available capacity.

Existing Loads

Air conditioning, lifts, pumps, machinery and other major equipment.

Proposed EV Load

Number of chargers, charger rating and expected simultaneous use.

Cables and Route

Cable size, route length, voltage drop and installation method.

Protection and Earthing

Breaker, RCD/RCBO, isolation, short-circuit protection and protective earth.

Typical Charger Load Examples

These are planning values. Final design depends on the charger, cable length, demand strategy and authority requirements.

What the Report Can Include

• Site and client details
• Existing supply and main breaker
• Existing load estimate
• Proposed EV load
• Total connected load
• Maximum-demand estimate
• Recommended cable and breaker
• Earthing observations
• Load schedule
• Single-line diagram where required
• Installation or load-increase recommendation

Does the Report Guarantee Approval?

No. Final approval belongs to the relevant electricity authority and may require an approved consultant, contractor, municipality, landlord or building management.

Authorities in the UAE

Dubai — DEWA

EV charging projects in Dubai must follow DEWA technical and regulatory requirements. Public charging operations may also require a CPO licence.

Sharjah — SEWA

SEWA is the electricity authority in Sharjah. Submission requirements depend on the site and project.

Northern Emirates — EtihadWE

Etihad Water and Electricity is the current name of the authority formerly known as FEWA.

Abu Dhabi — TAQA Distribution

TAQA Distribution provides electricity-load approval and load-upgrade inspection services. Documents may include drawings and load schedules.

Do You Always Need a Load Increase?

No. Some sites have enough spare capacity. Others can reduce the upgrade by using:

• Lower charger power
• Dynamic load management
• Scheduled charging
• Load sharing
• Phased installation

Example: Five 22kW Chargers

Five 22kW chargers have a connected rating of 110kW. However, approved load management can limit simultaneous demand and distribute the available power.

Who Needs This Service?

• Villa owners
• Apartment buildings
• Car showrooms
• Workshops
• Commercial parking
• Hotels and offices
• Fleet operators
• Developers and government projects

Our Process

1. Receive site and charger details
2. Inspect the electrical system
3. Calculate the EV load
4. Check panel, cables, protection and earthing
5. Recommend charger power
6. Prepare the report
7. Support the consultant or authority process where applicable
8. Install after approval

Conclusion

A load assessment helps prevent overloaded breakers, undersized cables, unsafe connections and unnecessary upgrade costs.

MEV Charger can inspect the site, calculate the load and prepare a clear technical report. Final approval remains subject to the relevant authority and approved project parties.
