Eaton 2P 100A EV Charger Emergency Shutoff Review

When hardwiring 80A EV chargers such as the Autel MaxiCharger 80A EV Charger, I don’t treat the EV charger’s emergency shutoff as an afterthought. At this power level, the shutoff is just as important as the charger itself.

I chose the EATON 2P 100A EV Charger Emergency Shutoff because I wanted something clearly built for high-amperage EV charging, not a light-duty switch pushed beyond its comfort zone.
From the start, this one felt like the right EV Charger Emergency Shutoff for a hardwired 80A EV charger installation.

Installation Experience

The first thing I noticed was the enclosure quality. It’s solid and rigid, with none of the flex we observed in the SIEMENS 2P 60A EV Charger Emergency Shutoff. That matters when mounting it outdoors, where vibrations, bumps, or temperature changes are common.

Inside, there’s plenty of working room. The spacing makes it easy to land larger EV charger branch circuit conductors without forcing bends or stressing terminals. That alone saves time and helps keep the install clean and professional.

NEC-Compliant Installation Setup

The non-fusible design works well for high-amperage EV charging and keeps the system simple. With an 80A EV charging continuous load, all charging current passes directly through this shutoff, so solid construction, EV charging branch circuit amperage support, and reliable contacts really matter here.

Overcurrent protection is handled upstream with a dedicated 100-amp double-pole breaker, sized correctly for continuous EV use. I paired it with #3 AWG copper conductors rated for 75°C, installed in properly rated conduit for the environment.

This setup fully supports the Autel MaxiCharger 80A EV Charger and follows NEC requirements for continuous loads. The Eaton shutoff serves as the required local disconnecting means under NEC Article 625, giving a clear and accessible way to shut down power at the charger. From both a safety and inspection standpoint, this configuration checks every box.

Real-World Use

In daily use, the shutoff does exactly what it should. The handle action is firm and decisive. When it’s switched off, there’s no doubt the charger is fully de-energized. That confidence matters when servicing equipment or explaining safety steps to a homeowner.

The labeling is clear and easy to read, even from a distance. In an emergency, no one has to guess which switch to pull.

Built for High-Amperage Charging

This shutoff pairs extremely well with the Autel MaxiCharger 80A, which is one of the best high-output residential chargers available. At 80 amps, everything upstream and downstream needs to be sized correctly, and this Eaton shutoff feels like it belongs in that system.

It doesn’t feel oversized or excessive. It feels appropriate, which is exactly what you want for continuous high-load equipment.

Durability and Environment

After being in service, the Alloy Steel NEMA 3R enclosure still looks solid. No loose hardware, no fading markings, and no signs of corrosion. Whether installed in a garage or outdoors, it’s clearly designed to hold up over time.

That long-term durability is important, especially for EV setups meant to last years without constant attention.

Any Downsides?

It’s larger than smaller safety switches, but that’s expected for a 100A-rated shutoff. For high-amperage EV charging, I see this as a benefit, not a drawback. The extra space improves wiring, heat handling, and overall reliability.

Final Thoughts

The EATON 2P 100A EV Charger Emergency Shutoff is a strong, dependable choice for serious EV charging installations. It installs cleanly, operates with confidence, and provides the safety margin an 80A charger demands.

We recommend this shutoff for high-amperage 80A EV charger installations, especially when using the Autel MaxiCharger 80A EV Charger. It’s a component I trust, and one I’d use again without hesitation.
