3. Upgrade or Expand Your DB Box
The distribution board (DB) is the core of your home’s electrical system. However, older DB boxes may lack sufficient circuit slots or still rely on outdated fuses and non-compliant circuit breakers. Using these can lead to frequent tripping, overheating, electrical fires, or even total power failure.
To enhance overall safety and performance, upgrade to a modern DB equipped with RCCBs (Residual Current Circuit Breakers) and MCBs (Miniature Circuit Breakers). These components are designed to detect faults, prevent electrocution, and protect your appliances from sudden voltage spikes. Also, consider installing separate circuits for lighting, air-conditioning, kitchen appliances, and general power points to maintain proper load distribution.
4. Ensure SS 638 Compliance
In Singapore, SS 638 compliance is mandatory. This code sets the benchmark for all residential and commercial electrical installations, ensuring safety, proper load handling, and installation standards. Non-compliance can delay renovation approval and put your home at risk.
Ensure that your contractor uses components approved by the Energy Market Authority (EMA) to meet regulatory standards. Additionally, proper wiring methods must be followed to guarantee long-term safety and system reliability. For residents of HDB flats or condominiums, they may need to submit documentation to their HDB branch or condo MCST for approval before work begins.
5. Coordinate with Renovation and Interior Design Teams
Electrical planning must go hand in hand with your overall renovation. From residential electrical services to concealed conduit routing, your electrician should work closely with your interior designer or renovation contractor.
Remember to provide your LEW with your final appliance list and layout plan upfront to avoid unnecessary hacking or delays later. A clear floor plan showing appliance locations allows for more efficient planning and smoother installation. Keep in mind that concealed wiring and trunking should always be installed before any tiling, carpentry, or ceiling work is carried out.
6. Allow for Future Expansion
As technology evolves, your electrical system should be ready to accommodate new additions. Whether it’s extra LAN ports, CCTV points, or future smart home hubs, plan ahead during the upgrade.
Leave spare capacity in your DB box and ensure enough space in your conduits for future wiring. If you live in a landed property, you might also want to prewire for electric gates or solar panels.
