A Distribution Board (DB Board) is the central point of your electrical system where power from the utility is distributed to various circuits throughout your property. It contains circuit breakers, earth leakage devices, and surge protection to ensure safe and efficient power distribution.
Power Distribution Hub
The main point where electricity is distributed to different circuits in your property.
Safety Protection Center
Contains safety devices that protect against overloads, short circuits, and electric shock.
System Control Point
Allows control and isolation of different electrical circuits for maintenance and safety.
Circuit Breakers
Earth Leakage
Surge Protection

Warning Signs Your DB Board Needs Attention
Don't ignore these warning signs - they indicate potential safety hazards.
Frequent Tripping
Circuit breakers trip regularly
Breakers that trip frequently indicate overloaded circuits, faulty wiring, or undersized protection. This can lead to complete electrical failure or fire hazards.
Burning Smell
Smoke or burning odor from DB
Any burning smell or smoke coming from your DB board indicates overheating wires, loose connections, or component failure. This is an immediate fire risk.
Old Fuse Box
Still using ceramic fuses
Ceramic fuses and old-style DB boards don't meet modern safety standards. They lack earth leakage protection and proper overload protection.

DB Board Upgrade FAQ
Common questions about distribution board upgrades.
Signs you need a DB upgrade include:
- Frequent circuit breaker tripping
- Still using ceramic fuses (old fuse box)
- Adding major new appliances (air conditioner, pool, solar)
- Burning smell or discoloration around DB
- No earth leakage protection (test button)
- DB is more than 20-25 years old
- Insufficient circuits for your needs
- Planning property renovations or extensions
We offer free DB assessments to determine if an upgrade is necessary.
The duration depends on the complexity:
- Simple DB replacement (like-for-like): 4-6 hours
- Standard DB upgrade (residential): 6-8 hours
- Complex upgrade (with rewiring): 1-2 days
- Commercial/Industrial: 1-5 days depending on size
We typically complete residential upgrades in one day with minimal disruption. For complex projects, we can arrange temporary power if needed.
Our standard DB upgrade includes:
- New DB enclosure with adequate ways for future expansion
- Main circuit breaker appropriate for your supply
- 30mA earth leakage protection device (essential for safety)
- Individual circuit breakers (MCBs) for all circuits
- Type 2 surge protection device (protects electronics)
- Proper labeling of all circuits
- Neat cable management and termination
- Comprehensive testing and verification
- Certificate of Compliance (CoC)
Additional items like additional circuits, sub-DBs, or specialized protection can be added based on your requirements.
Yes, in most cases. We use a systematic approach to minimize disruption:
- We install the new DB next to the old one first
- Transfer circuits one by one during the day
- Essential circuits (fridge, security) are prioritized
- Brief power interruptions (15-30 minutes per circuit)
- We coordinate timing to minimize inconvenience
For critical applications (medical equipment, servers), we can arrange temporary generator or UPS power during the upgrade.
In most cases, yes. Tripping problems are often caused by:
- Overloaded circuits: Modern DB allows proper circuit distribution
- Faulty old breakers: New breakers provide reliable protection
- Insufficient capacity: Upgrade provides adequate circuit capacity
- Earth leakage faults: New earth leakage device properly detects faults
However, if tripping is caused by wiring faults or faulty appliances, these issues need to be addressed separately. Our assessment identifies the root cause before we recommend solutions.
