100A Products
What Are Hubbell 100A Electrical Products?
Hubbell 100A electrical products are heavy-duty wiring devices and power connection solutions rated for 100-ampere service — one of the highest amperage ratings available in commercial, industrial, and marine electrical applications. These components are engineered to handle significant electrical loads reliably and safely, making them a go-to choice for demanding environments where standard residential-grade hardware simply won't cut it.
A 100-amp rating means these devices are capable of carrying sustained high-current loads without overheating, arcing, or degrading over time. Whether you're wiring a shore power connection on a vessel, setting up a generator transfer circuit, or powering heavy equipment at a worksite, 100A-rated components provide the headroom and safety margin that high-draw applications require.
What's Included in This Category?
Hubbell's 100A product lineup typically spans several essential device types, all sharing that robust 100-amp current rating:
- Locking Connectors & Plugs – Twist-lock style plugs and connectors are designed so the plug physically locks into the receptacle, preventing accidental disconnection under vibration or tension. This is especially critical in marine, RV, and industrial settings.
- Receptacles & Inlets – Panel-mount or surface-mount receptacles allow for secure, weather-resistant termination points. Inlets are commonly used on generators, transfer switches, and shore power pedestals.
- Pin & Sleeve Devices – Industrial-grade pin-and-sleeve connectors offer an IP-rated, watertight connection ideal for outdoor or washdown environments.
- Power Outlet Assemblies – Complete outlet and housing assemblies that integrate the connection point and enclosure into a single, ready-to-install unit.
Why 100A Electrical Ratings Matter
Electrical components are rated for a maximum continuous current load. Using an under-rated device in a high-current circuit is a significant safety hazard — it can cause the device to overheat, melt, or even catch fire. Selecting components that match or exceed your circuit's amperage ensures long service life and compliance with electrical codes such as the NEC (National Electrical Code) and ABYC standards for marine applications.
100-amp devices are particularly common in:
- Marine shore power systems (dockside power for boats and yachts)
- RV and campground power pedestals
- Generator interconnects and transfer stations
- Industrial machinery and heavy equipment hookups
- EV charging infrastructure and commercial electrical panels
Key Considerations When Shopping 100A Electrical Products
Before selecting a 100A device, consider the following factors to ensure you get the right fit for your application:
- Voltage Rating – 100A devices are available in multiple voltage configurations, including 125V, 250V, and 3-phase 480V. Always match the voltage rating to your circuit.
- NEMA or IEC Configuration – The blade or pin configuration of a plug or receptacle must match its mating device. Common 100A NEMA configurations include the L16-100 and CS8369-series twist-lock styles.
- Weatherproofing & IP Rating – For outdoor, marine, or wet-location use, look for weather-resistant housings and appropriate ingress protection (IP) ratings.
- Wire Range & Termination Type – Verify the device accommodates your conductor gauge (typically #1 AWG to #4/0 AWG at 100A) and your preferred termination method (screw, lug, or compression).
- Code Compliance – Ensure the product carries relevant listings such as UL, CSA, or CE marking for your jurisdiction and application.
Investing in properly rated, high-quality 100A electrical components is fundamental to safe, reliable power distribution — whether on the water, on the road, or at the job site.
