A restaurant places unusually high demand on an electrical installation. Cooking, extraction, refrigeration, dishwashing, hot water, air conditioning, lighting, payment systems and backup power may run together for long periods in a hot, wet and grease-contaminated environment.
A valid electrical COC and test report are essential for the qualifying fixed electrical installation, but they are not a restaurant operating licence. They do not replace a food-premises Certificate of Acceptability, fire clearance, gas documentation, approved building work or municipal trading requirements.
The strongest compliance process maps every load and responsibility boundary before opening, refurbishment, sale, lease hand-back or insurance review.
01
Know exactly what the restaurant COC covers
The COC should identify the installation or portion inspected and be accompanied by the relevant test report. It covers the qualifying fixed electrical installation—not every plug-in appliance, gas system, extraction performance issue or food-safety condition.
Where a tenant fit-out adds circuits, boards, isolators, signage, kitchen equipment or backup power, the added or altered work must be properly inspected, tested and documented. An older landlord certificate cannot prove that later restaurant work is compliant.

02
Build a kitchen load schedule before energising equipment
Equipment lists change during fit-out. A restaurant may add a fryer, combi oven, coffee machine, ice maker, water heater or extra refrigeration after the original design. The supply and distribution system must be checked against the equipment actually installed.
Record nameplate ratings, phases, starting currents and operating patterns. Consider what runs simultaneously during preparation and peak service, not merely the average bill.
- Ovens, fryers, grills, induction equipment and hot-holding units.
- Refrigerators, freezers, cold rooms and ice machines.
- Extraction fans, make-up air and air-conditioning systems.
- Dishwashers, glass washers and water-heating equipment.
- Coffee machines, point-of-sale equipment and small-power circuits.
- Signage, feature lighting and external areas.
- Generator, inverter and essential-load circuits.
03
Design for heat, water, grease and cleaning
Sockets, isolators, cable routes and enclosures must suit their location. Water, steam, hot surfaces, grease and pressure cleaning can damage equipment that would be acceptable in a dry office.
Provide accessible local isolation for fixed equipment where required, protect wiring from heat and mechanical damage, and keep electrical equipment out of positions where routine cleaning exposes it to water or chemicals. Repeated earth-leakage tripping should be diagnosed, not bypassed.
- Sinks, dishwashers and wash-down areas.
- Hot lines, ovens, fryers and extraction canopies.
- Cold rooms, condensers and defrost systems.
- Floor-level outlets and damaged flexible leads.
- Outdoor, delivery and refuse areas.
- Temporary appliances added during peak service.
04
Make the distribution boards understandable under pressure
Restaurant staff need to isolate a failed appliance without switching off the entire premises or guessing at unlabelled breakers. Board schedules, isolator labels and emergency instructions should match the live installation.
Review protective-device ratings, conductor sizes, circuit balance, earth leakage, signs of heat and the capacity of the incoming supply. Thermal damage and loose terminations often become visible only after sustained peak load.

05
Coordinate generators, inverters and essential restaurant loads
Decide which refrigeration, extraction, lighting, point-of-sale and safety systems must remain operational during an outage. The backup design should prevent backfeeding, use suitable changeover and protection, and match the real starting and continuous loads.
Label circuits excluded from backup and document the shutdown and restart sequence. A backup system that operates in one test mode may still overload when refrigerators, ice machines and extraction restart together.

06
Do not confuse the electrical COC with other restaurant approvals
A restaurant may need municipal business or trade-licence processes, a food-premises Certificate of Acceptability, fire clearance, approved building or occupation documentation and gas-system evidence. The exact list differs by municipality and premises.
For example, municipal guidance can require a Certificate of Acceptability and fire clearance as part of food-business processes. These documents address different risks and should be tracked separately in the opening file.
- Fixed electrical installation and applicable COC/test report.
- Gas installation and gas appliances where applicable.
- Food-premises hygiene and Certificate of Acceptability.
- Fire systems, extinguishers, extraction and emergency arrangements.
- Building, occupation, zoning and trade-licence requirements.
- Appliance service, cleaning and maintenance records.
- City of Tshwane trade licence guidance — Municipal example showing separate food, fire and business requirements.
07
Create one opening, acquisition or hand-back file
Before opening or taking occupation, record the landlord/tenant electrical boundary, review the existing COC, inspect all fit-out work and close defects. Before a sale or lease exit, test the final configuration after removals and reinstatement.
Keep certificates with their test reports, drawings, equipment schedules and alteration records. A one-page certificate separated from its scope and test evidence is difficult to interpret years later.

- Single-line diagram and board schedules.
- Applicable COC and test report for the final installation.
- Backup-power diagram and operating instructions.
- Defect, repair and commissioning records.
- Landlord/tenant boundary and acceptance record.
- Planned inspection and maintenance schedule.

FAQ
Questions readers also ask
Does a restaurant need an electrical COC in South Africa?
The responsible user or lessor must hold a valid COC for a qualifying fixed electrical installation. Restaurant additions and alterations must be properly inspected, tested and documented.
Does the electrical COC cover kitchen appliances?
It covers the applicable fixed installation, not automatically every plug-in or specialised appliance. Equipment may need separate servicing, inspection, product evidence or commissioning.
Is an electrical COC the same as a food Certificate of Acceptability?
No. The Certificate of Acceptability concerns food-premises hygiene. Electrical COCs, fire clearance, gas evidence and business-licence requirements are separate.
When should the restaurant be tested?
After the final fit-out is complete, after material alterations, before opening or occupation when records are uncertain, and after damage, fire, flooding, overheating or major equipment changes.
Can the landlord’s old COC cover a new restaurant fit-out?
It cannot prove the compliance of later tenant additions. Review its scope and obtain the appropriate certification and test evidence for the altered work.
Why does a restaurant trip only during busy service?
Peak simultaneous load, heating cycles, refrigeration starts, damaged equipment, moisture or loose connections can reveal problems not present during quiet periods. A measured load and fault investigation is required.
