Installation notes

Before you install.

Open a question for model-specific guidance and sources.

Verified against the manufacturer's documentation (rev. PK-93792-10-00-2B AR0088; product specifications), checked 2026-10-20. Manufacturer documentation →

Which receptacle is this?

Leviton GFTR2-MW is a tamper-resistant GFCI receptacle rated 20 A / 125 V, including 20 A feed-through, for nominal 120 V circuits. Its Class A leakage threshold is 5 mA ±1 mA. Confirm the installed environment and product variant.

What do LINE, LOAD and PLUG mean?

The installation sheet distinguishes incoming LINE from protected downstream LOAD wiring. PLUG marks the receptacle face in this diagram. The common ground connection remains separate from the switching contacts.

What does the example check?

The drawing keeps both current-carrying conductors paired through the device and preserves earth. It includes upstream branch overcurrent protection. Reset and Tripped change contacts manually; leakage sensing, reset interlocks, automatic trip times and physical commissioning tests are not simulated.

Specifications and terminal map.

Check the model, ratings and connection points against your own unit before choosing installation hardware.

Catalog specification

Leviton GFTR2-MW 20 A / 125 V GFCI receptacle for nominal 120 V circuits, with Class A 5 mA ±1 mA leakage response. LINE is the supply; LOAD is protected downstream wiring; PLUG represents the receptacle face. Separate branch overcurrent protection is required. Only manual contact states are modeled.

The map identifies line, neutral and protective-earth connections. This page does not calculate an AC cable size or protection rating.

Sources and connection guidance

Equipment specifications. Model details, ratings and terminal roles come from the catalog. Check your unit’s label and current manufacturer documentation for its exact revision.

AC planning boundary. The drawing identifies conductors and connection points; supported switching states show contact continuity only. Crimp does not calculate AC load flow or verify fault protection, leakage trips, source isolation or grounding. This overview does not calculate cable sizes or validate protective devices. Follow the complete manufacturer installation instructions.
