Splicing and tapping conductors is one of the most fundamental parts of any electrician’s job. When running power, choosing the right style or configuration of connector can make all the difference in saving you time and money. Each type of connector has a particular application where it excels.
Polaris® has a robust portfolio suited for most applications. Our connectors have between 2 and 12 wire ports, accept a wide range of wire sizes (#14 AWG to 750 KCMIL), have varying configurations like inline, single-side or dual-side entry and work in dry or wet applications. We are the original innovator of modern pre-insulated connectors, giving us over 35 years of experience in the category.
Polaris pre-insulated connectors are in general, simple enough to understand—all of them allow for passing current between conductors of the same or different type and size. Polaris pre-insulated parts are used in line- and load-side applications when splicing and tapping.
These connectors can vary from each other quite a bit, based on application, number of ports and port orientation, but they all have the same fundamental design. Each port features a screw which can be wound open then tightened down onto the inserted conductor, forming a secure join to the metal body of the connector. Unused ports are then covered by plugs.
There are two key benefits of choosing a pre-insulated connector:
- They install faster than other options
- No need for cover or taping
- Installs with just a torque wrench
- Ergonomic rounded shape
- They form safe and secure connections
- Sealed against dirt, moisture or debris
- Options for challenging applications
Pre-insulated connectors are a complete solution, without any need for additional cover or taping. The insulation coating the connector saves time and effort—once its installed, your job is done!
Installing a pre-insulated connector is easy: simply brush the conductors clean, strip back their insulation, insert one conductor into each port and secure the covered pressure screws.
The insulation coating results in an ergonomic rounded design. If you’re installing many of these or working in the tight confines of a cable tray or raceway, protecting your hands is a priority.
Every port—including the screws ports—have their own plugs, allowing you to seal the connector against moisture or debris. Some connectors are specially designed for direct burial or temporary submersion.
The Perfect Pre-Insulated for Your Job
There are pre-insulated connector options designed for any application, like Polaris Grey, which is specialized for fine-stranded wires. All of our connectors’ insulation layers are resistant to abrasion and chemicals, but some are also UV-resistant for exposed use or clear to allow for a visual check.
Once you see the benefits of pre-insulted connectors, it can be hard to go back. But you still have to choose a brand—and when it comes to electrical connectors, the original is still the best. Polaris is an established brand with a reputation for innovation and quality. We carry a huge range of sizes and configurations, with custom manufacturing available for the truly unique jobs, and even have options rated for parallel configurations.
We know electrical connectors, and we manufacture ours in America to guarantee the highest standard of quality with quick lead times. Try them for yourself and see why Polaris, the original pre-insulated connector, is still the brand most asked for by name.
