        NLS 30399 | 2 x 35mm Heavy Duty Double Screw Connector

        The NLS 30399 BP connector is a heavy-duty insulated joiner for two 35mm² copper conductors. Rated at 80A, it supports active, neutral and earth conductors in high-load applications. A brass connector body paired with a clear flame-retardant PVC insulator provides durable performance with visibility of cable placement.

        This BP connector uses a double-screw design with deep slotted heads for a tight, secure clamp, and comes with screws backed off for quick installation. Sold individually (box of 10), it’s ideal for large-capacity cable joining and terminal work.

        NLS 30399 Features

        • 35mm² capacity: Suits large flexible copper conductors.
        • 80A current rating: Handles high-load circuits with ease.
        • Double screw retention: Two deep slotted screws for a secure grip.
        • Brass connector body: Ensures strong, stable electrical contact.
        • Clear flame-retardant PVC insulator: Provides protection and visual confirmation of connection.
        • Backed-off screws: Supplied ready for fast installation.
        • Active, neutral, earth compatible: Versatile for general or heavy-duty wiring.

        Where to use this NLS 30399

        • Joining 35mm² conductors in high-load circuits and submains.
        • Terminal connections requiring a secure, insulated joiner.
        • Switchboards and large cable runs where 80A-rated connections are required.
        • Service or upgrade work involving oversized cables.

        (30399)

        It is designed for two 35mm² copper conductors, making it suitable for large-capacity joins in high-load circuits.

        The connector is rated at 80A, supporting heavy-duty submains, switchboard feeds and other high-load wiring applications.

        Each conductor is secured by two deep slotted screws, providing a firm mechanical clamp and reliable electrical contact.

        No, this connector is intended for copper conductors only.

        Use the NLS 30399 when joining 35 mm² conductors or when an 80 A-rated, robust insulated joiner is required, especially in high-load submains, switchboards, or large cable runs.
