Insulated Connectors for Power Distribution – Clear & Black Insulated Mechanical Connectors
Explore our dedicated selection of insulated connectors for power distribution and feeder circuits. This collection is part of our broader Connectors category and focuses specifically on insulated mechanical splice and multi-cable connectors – not terminals. Here you’ll find only heavy-duty insulated connector blocks designed for joining and distributing conductors in gutters, raceways, enclosures, panelboards, and similar applications.
Two Main Families: Clear & Black Insulated Connectors
To make it easier to shop, this collection is organized into two major sub-collections:
- Clear Insulated Connectors – Transparent insulated bodies that allow visual confirmation of conductor insertion and torque. Includes in-line and multi-cable clear insulated mechanical connectors in a wide range of wire sizes and port configurations.
- Black Insulated Connectors – Opaque black insulated mechanical and multi-cable connectors designed for demanding power distribution applications, available in single side entry, dual entry, and multi-port configurations.
Each of these sub-collections is further broken down into focused groups such as in-line insulated connectors and multi-cable insulated connectors (single side entry, dual entry, and other layouts), helping you quickly drill down to the exact style and wire range you need.
What These Insulated Connectors Are Designed For
These products are insulated mechanical power connectors, ideal for:
- Splicing and branching feeders and tap conductors
- Power distribution inside gutters, raceways, and enclosures
- Panelboard and switchgear terminations (where allowed by code)
- Industrial and commercial power distribution upgrades or retrofits
- Any application where an insulated splice or multi-port connector is preferred over open mechanical lugs
They are not ring terminals, spade/fork terminals, butt splices, or small crimp-style terminals. Instead, they are robust, block-style insulated connectors designed for larger conductors and higher-current applications.
Key Features of Our Insulated Mechanical Connectors
- High-Dielectric Insulation: Rugged rubber or plastisol coatings provide excellent electrical insulation and abrasion resistance.
- Dual-Rated for Copper & Aluminum: Many connectors are CU9AL dual rated for copper or aluminum conductors, simplifying material selection and inventory.
- Pre-Filled with Oxide Inhibitor: Factory-filled to help reduce oxidation and improve long-term conductivity at the connection point.
- Wide Wire Range: Models cover a broad spectrum – from smaller branch circuit conductors up to large feeder sizes, depending on the specific connector.
- Multiple Ports & Configurations: In-line, single side entry, dual entry, and multi-port layouts for flexible tap and distribution layouts.
- Easy Re-Entry: Many designs allow re-entry for inspection, troubleshooting, or future changes when needed.
- 600V Ratings: Suitable for standard low-voltage power distribution applications (check each product spec sheet for exact ratings and approvals).
How to Use This Collection
Start here if you know you need an insulated mechanical connector rather than a bare lug or compression terminal. From this page, simply choose between:
- Clear Insulated Connectors – when visual verification of conductor position is critical.
- Black Insulated Connectors – when a traditional opaque insulated connector is preferred.
Within each sub-collection, you can then narrow down by connector style (in-line, multi-cable, single side entry, dual entry, etc.), wire range, number of ports, and other key specs. Each product page includes detailed technical information, including dimensions, wire size ranges, material, voltage rating, and insulation type, so you can match the connector to your application and code requirements.
