You're right to check the codebooks! The requirement for GFCI protection for 14-50 receptacles in garages has evolved over time. Here's the breakdown based on typical NEC adoption cycles: 2020 NEC

This is where the change happened.

The 2020 NEC required GFCI protection for 125V through 250V receptacles rated 50 amps or less installed in garages. The language is in 210.8(F)

Therefore, depending on the state/local jurisdiction's adoption of the NEC, 2020 is the earliest you would likely see this requirement. However, keep in mind that some jurisdictions might have been on older versions of the NEC.

Important Considerations



Local Amendments

Always, always check for local amendments to the NEC. Some jurisdictions may have adopted the GFCI requirement earlier than the 2020 NEC. Or they might have grandfathering clauses for existing installations.

Specific Use Case

What the receptacle is used for might influence interpretation. Even before the 2020 NEC explicitly required it, an inspector might have cited other code sections requiring GFCI protection if the receptacle was clearly intended for portable appliances or equipment used in damp/wet locations (which garages can sometimes be).

Date of Installation

The code version in effect at the time of installation is generally the one that applies. If the receptacle was installed before the jurisdiction adopted the 2020 NEC (or local amendment), it likely wasn't required to have GFCI protection at that time.

"Garage" Definition

Make sure the space qualifies as a "garage" under the NEC definition. If it's a detached workshop or something similar, the rules might be different.To get the definitive* answer for a specific installation, you'd need to:1.

Identify the year the receptacle was installed.2. Find the NEC code version in effect in that jurisdiction at that time. (Your local building department or electrical inspector can tell you this.)3. Check for any local amendments to that code version.
