Expert ScoreRead review

The Southwire 6/2 Gauge Wire for EV Charger (Stranded) installations is an excellent option for electricians and DIY enthusiasts wiring indoor circuits for EV chargers. Its robust construction, reliable performance, and easy-to-handle design make it a top choice for EV charging applications. For outdoor or underground installations, consider using a conduit with THHN wires or UF-B cable for added durability.

The Southwire 6/2 Gauge Wire for EV Charger (Stranded) (6/2 NM-B Wire – Stranded) is a reliable choice for installing hardwired Level 2 EV chargers. Designed for indoor use, this 6 gauge wire for EV charger installations delivers efficient and safe performance when wiring 50 amps EV charger circuits. The cable includes two 6 AWG stranded conductors and a 10 AWG bare ground wire, all protected by durable insulation that meets NEC standards.

The wire’s 6/2 configuration is ideal for powering 40Amps EV chargers such as Level 2 wall-mounted units on a 50Amps dedicated circuit breaker. We recommend flexibility and ease of handling during installation. The SIMpull jacket further simplifies routing the wire through conduits, walls, and joists, saving time and effort.

We recommend this 6/2 wire for a Tesla charger especially when it’s a 240V hardwired installation that doesn’t require a neutral conductor, wire terminals inside the Tesla Wall Connector are designed to accommodate up to 6 AWG, which makes this wire ideal for its installation. However, for NEMA 14-50 outlet installations, which require a neutral, you should opt for 6/3 NM-B W/G Wire instead.

Southwire ensures consistent product quality, and this cable is no exception. The 10 AWG ground wire offers reliable grounding for safety, while the thick outer sheath resists wear and tear. The stranded copper conductors provide excellent conductivity, minimizing voltage drop over long runs.
