Tips

• Professional Installation Required: This distribution board must be installed, tested, and commissioned by a qualified and certified electrician in accordance with local wiring regulations and SANS 10142-1.
• Wall Cavity Preparation: Ensure the wall opening and cavity depth are correctly sized for the flush mount enclosure. Allow for secure fixing of the enclosure base.
• Making Good: Plan for plastering or finishing around the enclosure frame to achieve a neat, flush finish.
• Cable Entry: Plan cable entry points into the enclosure before fixing it into the wall.
• Torque Settings: Ensure all terminal connections are tightened to the manufacturer's specified torque values.
• Earth Leakage Testing: Regularly test the earth leakage device by pressing the "T" (Test) button (monthly is recommended).
• Safety First: Always isolate the electrical supply before opening the distribution board cover or performing any maintenance. Lethal voltages are present inside.
• Accessibility: While flush-mounted for aesthetics, ensure the board remains accessible for future maintenance, testing, and inspection.
