        NLS | 12 Pole Surface Mount Switch Board 100A 250/415V | IP40

        The NLS 30182 is a 12-pole surface-mount distribution board rated up to 100A at 250/415V (50/60Hz), designed for the Australian domestic electrical market. The 30182 suits upgrades from older fuse-based boards to modern RCBO or MCB protection and is widely specified for residential renovations, site offices, sheds, and small commercial installations. It complies with IEC standards and is made of fire-resistant polycarbonate.

        Switchboard upgrades and protection retrofits often call for a board that balances feature set with budget constraints. The 30182 accommodates most leading brands of circuit protection devices including RCBOs, RCDs, and MCBs without requiring adapters or custom fabrication. Electricians value the compact footprint paired with generous internal space, which streamlines wiring and reduces on-site rework. The included earth bar and neutral links eliminate the need to source separately, speeding up the complete-fit-off and reducing job costs.

        Compact size is the hallmark of the NLS 30182 range, yet the board delivers straightforward wiring layout and ample internal space for neat circuit routing. The reasonable price point makes the 30182 a natural choice for value-conscious installers and renovators who refuse to compromise on component quality. DIN rail mounting and included identification labels mean the board reads clean on final inspection, instilling confidence in the householder and simplifying future service calls.

        Features

        • 12-pole capacity — accommodates up to 12 standard 18mm-wide protection devices (MCBs, RCBOs, RCDs) from major brands including Schneider, Hager, Clipsal, and HPM.
        • Smoke-tinted transparent door — allows clear visual inspection of circuit breakers and switches without opening the enclosure, speeding diagnostics and routine checks.
        • Earth and neutral busbars included — moulded terminal blocks for neutral and earth conductors are supplied ready to install, eliminating the need for separate terminal blocks and reducing wiring time.
        • Full DIN rail supplied — pre-installed industry-standard DIN rail accepts all common circuit protection devices without requiring additional rails or adapters.
        • Pole fillers and identification labels included — blank pole fillers seal unused slots and the supplied circuit labels allow clear, professional marking of final circuits for maintenance and safety compliance.
        • IP40 rating — suitable for indoor use in dry locations; not weatherproof and not rated for external mounting or damp exposed areas.
        • Up to 100A rating — rated for on-load currents of 100A (single-phase) or 63A (three-phase), covering the majority of domestic and small commercial distribution scenarios.
        • Fire-resistant polycarbonate enclosure — complies with IEC standards for electrical safety enclosures and resists impact and UV degradation better than standard plastic.
        • Compact dimensions — measures approximately 256mm length, 210mm width, and 100mm depth, fitting standard cavity spaces in walls and tight cupboard installations.
        • One-year warranty — covered under NLS manufacturer warranty for domestic and commercial use; in-home support available through authorized dealers.

        Where to use

        • Domestic switchboard upgrades — replacing outdated fuse boxes with modern RCBO or RCD protection during renovations, extending or rewiring existing homes.
        • Residential renovations and extensions — new additions, kitchen rewires, and full house rewiring projects where a compact, value-focused board fits the budget and site footprint.
        • Rental properties and holiday homes — straightforward protection layout and clear labelling reduce tenant/guest confusion and simplify ongoing maintenance and inspections.
        • Site offices and portable buildings — temporary or semi-permanent installations on construction sites, relocatable homes, and site office installations where a full-size board is overkill.
        • Garden sheds and outbuildings — powering workshop tools, garden lighting, and auxiliary services on residential properties with a compact, cost-effective load centre.
        • Small commercial installations — retail fitouts, small offices, and service provider bases requiring basic circuit protection without the cost or space footprint of industrial switchboards.
        • RCD or RCBO retrofit work — upgrading older MCB boards to incorporate RCD earth-leakage protection as required by AS/NZS 3000 amendments and state electrical compliance codes.

        The NLS 30182 is not suitable for external mounting, wet or damp locations, or installations where IP54 or IP65 weatherproofing is required. Do not install the 30182 outdoors, in bathrooms, laundries, or near pools or irrigation systems. For external installations, the NLS weatherproof range (IP54 and IP65 models) is the correct choice.

        Verified Sparky Direct customer reviews: NLS 30182 | 12 Pole Surface Mount Switch Board IP40 (30182)

        "Great value for money." — Alan

        "Very good product at a reasonable cost." — Ray Hartley

        "Perfect for a switchboard upgrade, very convenient size with all necessary components." — Kev

        (30182)

        The 30182 accepts most standard 18mm-wide single pole MCBs, RCBOs, and RCDs from leading brands including Schneider Electric, Legrand, Hager, and NLS. Confirm device width with the device datasheet or your supplier before ordering, as non-standard industrial breakers may not fit the DIN rail spacing.

        Installation must be carried out by a licensed electrician. The board is supplied pre-assembled but requires qualified termination of incoming mains, correct earth and neutral bar bonding, and compliance with AS/NZS 3000 and local electrical codes. All switchboard work in Australia must be done by a licensed professional.

        No. The IP40 rating is designed for dry indoor installations only. It is not suitable for external walls, weatherproof exposures, garages, laundries, poolside locations, or any area subject to moisture or temperature extremes. External installations and wet areas require IP54 or IP66 rated alternatives.

        The 12 pole positions accommodate up to 12 single pole devices (such as 12 × 10A MCBs, or a mix of 2 pole and 3 pole devices with appropriate filler strips). If future loads exceed 12 poles, a larger board (18 or 24 pole) must be installed as a replacement, not an addition.

        The complete kit includes the polycarbonate enclosure, pre-installed DIN rail, earth bar, neutral links, pole fillers, backboard, screws, and a sheet of circuit identification labels. No assembly is required on arrival; unpack and install protection devices and incoming/outgoing cables.

        The NLS 30182 is covered by the manufacturer's standard warranty against manufacturing defects. Specific warranty terms vary by region and supplier; contact Sparky Direct or NLS directly for details. The polycarbonate enclosure is built to last the service life of the installation if kept in a dry location.

        The 30182 can be used as a main board on modest installations (small homes, sheds, site offices) where the total electrical load is within the capacity of 12 circuits. On larger homes or commercial premises, it is typically used as a sub-board downstream of the main board. Consult a licensed electrician to determine the correct board size for your load.

        The 30182 combines a compact external footprint with generous internal wiring space, pre-installed DIN rail, and polycarbonate fire-resistant construction that holds its IP rating across years of service. It accommodates most major circuit protection brands without fitment issues, making it a straightforward drop-in solution for electricians across residential retrofits and new builds.

        The IP40 polycarbonate body protects internal terminals from accidental contact and dust ingress in indoor environments. The pre-installed earth and neutral bars ensure correct bonding, and the DIN rail mounting prevents device spacing drift that can occur with cheaper alternatives, reducing the risk of terminal arcing and fire.

        The board supports up to 12 final circuits, which suits most modest homes, extensions, and site offices. If your load grows beyond 12 poles, a larger 18 or 24 pole board must replace it. Plan for 20–25 percent spare capacity at install time to reduce the likelihood of a future upgrade.

        The NLS 30182 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
