NEMA 14-50 receptacle

Trade jargonOhio homeowner glossaryCC-BY-4.0

TL;DR

A NEMA 14-50 receptacle is the four-prong, 250-volt, 50-amp outlet — long familiar from RV parks and electric ranges — that has become the standard plug-in point for Level 2 EV charging at home. Wired with 6-gauge copper on a 50-amp two-pole breaker, it supports chargers drawing up to 40 amps continuous, and the NEC requires GFCI protection for it in garages.

Definition

What it means

A NEMA 14-50 receptacle is the four-prong, 250-volt, 50-amp outlet — long familiar from RV parks and electric ranges — that has become the standard plug-in point for Level 2 EV charging at home. Wired with 6-gauge copper on a 50-amp two-pole breaker, it supports chargers drawing up to 40 amps continuous, and the NEC requires GFCI protection for it in garages. Spec-grade or EV-rated versions are strongly preferred, as bargain receptacles have melted under daily charging heat.
