Browse our expert-reviewed archive of Zinsco-compatible circuit breakers built to support safe, code-compliant home and commercial electric vehicle (EV) charger installations.
All breaker listings and reviews are handpicked by our licensed electricians and certified EV charger installers to ensure reliable circuit protection for your EV charger, based on both charger and panel amperage. We’ve reviewed popular Zinsco breakers like the RC models, as well as rarer series such as the HQ breakers, all of which we have hands-on experience with.
At Electric Vehicle Geek, we help homeowners, electricians, and EV enthusiasts install and upgrade circuits for Level 1 and Level 2 EV chargers. Our Zinsco breaker listings highlight safe, reliable options—evaluated for performance, compatibility, and the ability to handle continuous EV charging loads without nuisance EV charger circuit breaker tripping. Each review includes detailed guides on breaker types, amperage, single-pole and double-pole compatibility, wiring diagrams, wire sizing, and EV charger compatibility.
Zinsco panels were widely used across North America for decades and are still present in many older homes. While the original Zinsco breakers are no longer manufactured due to safety concerns, certified replacement breakers make it possible to upgrade existing systems without a full panel replacement – especially when adding a dedicated EV charger circuit.
Our Zinsco Breakers reviews and product selections are based on:
Firsthand EV charger installation experience
Independent EV charger & accessories testing
Up-to-date NEC and manufacturer guidance
Decades of electrical and EV charging expertise
Whether you’re a homeowner, EV installer, or licensed electrician, selecting the right Zinsco breaker for EV charging is critical for safety and performance. Our circuit breaker reviews include detailed specs—amperage ratings, single-pole or double-pole configuration, and panel compatibility.
