Ideal Use

• New, large-scale luxury residential properties and custom-designed homes.
• High-specification renovations demanding completely concealed electrical infrastructure.
• Multi-dwelling units or apartment complexes where centralized, high-capacity flush boards are specified.
• Small to medium commercial buildings, boutique hotels, or modern office spaces designed with integrated services.
• Installations within drywall, brick, or block wall structures during new construction, requiring maximum circuit capacity and future-proofing.

Tips

• Exclusive Professional Installation: This high-capacity flush mount distribution board must be installed, thoroughly tested, and commissioned only by a qualified, certified, and registered electrician, strictly adhering to SANS 10142-1 and all applicable local wiring regulations.
• Meticulous Wall Cavity Preparation: Ensure the wall opening and recess depth are prepared with high precision according to the flush mount enclosure's specifications (DB-ST-18W-PF: approx. 365mm L x 217mm W x 85mm D for the box). The enclosure base must be securely and squarely fixed.
• Perfect Wall Finishing Integration: Coordinate with plasterers or drywall installers to ensure the wall finishing (skimming, plastering) around the enclosure frame results in a perfectly seamless and flush aesthetic.
• Considered Cable Management: Pre-plan and carefully manage all cable entries into the enclosure before final fixing into the wall cavity, ensuring no strain on cables or terminals.
• Adherence to Torque Specifications: It is absolutely critical that all terminal connections (main incomer, earth leakage, MCBs, neutral/earth bars) are tightened precisely to the manufacturer's specified torque values to prevent any future issues.
• Systematic Earth Leakage Testing: Establish and maintain a schedule for regularly testing the earth leakage device by pressing its "T" (Test) button (monthly is highly recommended) to verify its ongoing life-saving functionality.
• Rigorous Safety Before Access: Before attempting to access the interior of the distribution board for any reason (adding circuits, inspection, maintenance), the main electrical supply MUST be completely isolated, locked out, and tagged out.
• Documentation and Accessibility: Despite its concealed nature, ensure the installed board's location is documented and remains reasonably accessible for future maintenance, testing, and circuit identification. Clear internal labeling of all circuits is essential.
