Insulated studs

The Pro Installer insulated studs are a smart choice for marine installers. Increased stainless steel stud length allows up to three large cable lugs to be connected. The clear polycarbonate cover provides insulation/protection, while the snap-out side skirts allow for additional cable entry. The power tapping plate variant provides additional termination points for small cables.



• Modular sizing and common interconnection height: Easily linked with other Pro Installer Busbars and Fuseholders saving installation time and space

• Power tapping plate converts from a single stud, adding four connection points for smaller cables, while preserving access for larger cables

• Generous stud lengths allow securing of three 95mm2 (3/0) cable lugs

• Innovative clear covers provide insulation/protection, with “snap outs” for extra cable access as required

• Label recess on cover allows fitting up to 1⁄2” width (12.7mm) printed labels

• Snap out partition on double stud base provides insulation to separate studs for isolated (positive/negative) application. Snapping this partition allows easy linking of the studs

• Insert moulded studs offer superior mechanical strength

• Four mounting holes in base allow installer choice of using two, or four fastenings depending on level of securing required

• Designed for the harsh marine environment



• Note: no power passes through the stud so no amp rating is given

• 50 VDC

• High temperature, fiber reinforced plastic base provides strength and chemical resistance

• Clear poly carbonate cover

• Stainless steel studs/screws, and nickel plated brass nuts for longevity in the marine environment

• All threads are metric

• Double studs feature "snap out" insulating partition, to allow linking of studs
