        National Light Sources | White Pole Filler 6 Module | Electrical Accessories

        The NLS 30424 is a white pole filler used to cover unused sections of an electrical switchboard or sub-board that may expose live parts. The 30424 is 108mm long and 52mm high, and is supplied with 2 full (18mm) fillers and 8 half (9mm) fillers to suit DIN rail configurations.

        Electricians often face gaps in switchboards after removing failed devices or during retrofit work where circuit protection is being relocated. The NLS 30424 closes these gaps safely, preventing accidental contact with live conductors and meeting Australian standard practice to block access to live cables. On the jobsite, these fillers snap off at pre-scored break lines, so a single pack covers most filler needs without carrying multiple products.

        Licensed electricians stock these as a must-have in the van because they are inexpensive, fit all standard DIN installations, and work with any manufacturer's switchboard. The quick snap-fit design cuts install time, and the cost versus name-brand alternatives is a solid margin play on residential and commercial retrofit jobs. Supply one pack on every quotes with switchboard work and customers appreciate getting a complete, safe installation rather than an incomplete board.

        Features

        • 6-module configuration — supplied with 2 full (18mm) pole fillers and 8 half (9mm) pole fillers, covering most DIN rail gaps on standard switchboards.
        • Pre-scored break lines — allow sections to snap off cleanly without tools, so the 30424 fits single-pole, two-pole, three-pole, and four-pole applications from one pack.
        • White finish — matches Clipsal, NLS, Hager, and other major switchboard brands, maintaining a neat appearance on display homes and rental properties.
        • Live parts protection — complies with Australian standard practice to cover and limit access to live conductors, closing gaps that could expose circuit protection or busbars.
        • Universal fit — works on all standard DIN rail switchboards and sub-boards regardless of manufacturer or breaker type.
        • Low cost — delivers excellent value compared to name-brand alternatives, supporting healthy margins on retrofit quotes.
        • On-site essential — every electrician's van needs a pack; pre-scored fillers snap off on demand, so there's no need to carry multiple sizes or brands.

        Where to use

        • Switchboard retrofit work — the NLS 30424 covers DIN rail gaps left after removing failed MCBs, RCBOs, or older breakers during upgrades and repairs.
        • Sub-board installations — fills unused pole spaces when sub-boards are first installed with fewer breakers than the board capacity, preventing live-part exposure.
        • Renovation and new-build boards — used during initial installation to close gaps until final circuits are added, meeting compliance requirements from day one.
        • Residential and commercial jobs — standard filler for any switchboard type, on both domestic single-phase and commercial three-phase installations.
        • Display homes and rental turnover — ensures a complete, professional appearance and meets safety standards for properties with no final circuit configuration yet.
        • Rental maintenance and upgrades — used when existing breakers are removed or relocated, preventing dangerous gaps that attract compliance citations.

        The NLS 30424 is not suitable for live parts that generate heat (such as overloaded busbars) or for direct contact with water or chemicals. Install only on dry, indoor switchboards and sub-boards, and never use as a substitute for proper circuit protection. Do not install the 30424 in damp, wet, or corrosive environments, or in applications requiring fire-rated enclosures.
