Thorough Inspection and Tests are Carried Out During a Electrical Compliance Inspection, but What Do We Look For During Our Inspection?
Many homeowners and property owners assume that an Electrical Certificate of Compliance (COC) inspection is simply a quick look at the distribution board. In reality, a proper compliance inspection is a detailed assessment of your entire electrical installation to ensure it meets South African safety regulations.
At Thermoelectrics, we take every inspection seriously because your safety and compliance are our top priorities.
1. Distribution Board (DB Board)
The distribution board is the heart of your electrical installation. During our inspection, we check:
- Correct labelling of all circuit breakers
- Signs of overheating or damage
- Secure connections
- Proper breaker sizing
- Main switch operation
- Earth leakage protection
- Compliance with SANS requirements
A faulty distribution board can create serious fire and safety hazards if left unchecked.
2. Earth Leakage Unit
The earth leakage device is designed to protect people from electric shock.
We test:
- Correct operation
- Trip time
- Trip sensitivity
- Overall functionality
A non-functioning earth leakage unit could mean dangerous faults are not detected.
3. Earthing and Bonding
Proper earthing is one of the most important parts of any electrical installation.
We verify:
- Earth continuity
- Main earth connection
- Bonding of metallic components
- Water pipe bonding where applicable
Without proper earthing, electrical faults may not disconnect safely.
4. Plug Points and Socket Outlets
Every accessible socket outlet is visually inspected for:
- Physical damage
- Secure mounting
- Correct polarity
- Signs of overheating
- Compliance with regulations
Loose or damaged sockets can become a significant fire risk.
5. Lighting Circuits
We inspect lighting installations to ensure:
- Safe wiring practices
- Secure fittings
- No exposed live conductors
- Proper switching arrangements
- Compliance with installation standards
6. Wiring Throughout the Property
Our inspection includes checking visible wiring for:
- Mechanical damage
- Incorrect joints
- Exposed cables
- Overloaded circuits
- Poor workmanship
- Unsafe alterations
Electrical work performed by unqualified individuals often fails in this area.
7. Isolation and Main Switches
We ensure that:
- Main isolators operate correctly
- Circuits can be safely isolated
- Switchgear functions as intended
- Emergency shutdown is possible when required
8. Circuit Protection
Every circuit should be protected by the correct breaker size.
We verify:
- Correct breaker ratings
- Suitable cable sizes
- Proper overload protection
- Short-circuit protection
Incorrect protection can lead to overheating and electrical fires.
9. General Safety Inspection
Beyond technical testing, we also look for:
- Exposed live parts
- Unsafe DIY modifications
- Damaged accessories
- Missing covers
- Extension cords used as permanent wiring
- General hazards that could place occupants at risk
10. Electrical Testing
Using calibrated testing equipment, we perform a range of electrical tests, including:
- Earth continuity testing
- Earth loop impedance testing
- Insulation resistance testing
- Polarity verification
- Earth leakage testing
- Voltage measurements where required
These tests help identify faults that cannot be detected through visual inspection alone.
