Leviton 20 Amp, 20A-125V Isolated Ground GFCI Receptacle (GFTR2-IGO)
Features include high HF nuisance-tripping immunity, enhanced compatibility with electronics, wraparound steel strap for structural integrity, and a dual-function indicator light for power and proper wiring status. Best for industrial settings and equipment-heavy spaces where reliability matters. Consider this when your outlets power sensitive tools or communication devices in demanding environments.
Leviton 15A-125V Isolated Ground GFCI Receptacle (GFTR1-IGO)
Best for hard-use environments requiring compact, lighter-duty GFCI protection with isolation. Features wraparound steel strap for durability, a dual-function indicator, and wiring assistance during initial setup. Choose this if you need a robust 15A option that is easy to install in dense panels or tight spaces.
Leviton Straight Blade Isolated Ground 20A (5362-IGE)
Best for installations that favor a straight blade design with isolated ground. Notable for its compact size and straightforward terminal layout. Best for spaces where a two-pole, 3-wire configuration is standard, and the focus is on reliable isolation with simple wiring.
Leviton 20A-125V Non-Tamper-Resistant With Isolated Ground (MGFN2-GY)
Best for projects needing a modular option that requires a separate mating wiring module. Includes dual-function status indicator for clear feedback on power and protection status. Useful when wiring modules are purchased separately for larger installations. Note that the wire module is sold separately, so plan for additional components.
Leviton 20A Isolated Ground Duplex (5362-IG, Orange)
Best for industrial-grade installations requiring a rugged, orange-colored isolation receptor. Features include an impact-resistant thermoplastic cover and body, a single-piece brass mounting strap on heavy-duty devices, and a steel strap on more demanding models. Choose this when the environment benefits from heavy-duty construction and clear visibility of the device type.
Buying Guide
What makes an isolated ground GFCI receptacle the right choice?
- Isolated Ground purpose: IG outlets dedicate the ground path to minimize interference for sensitive equipment. This is essential for labs, recording studios, or medical devices.
- Amperage needs: Choose 15A for typical home outlets or 20A for higher-demand circuits. Industrial-grade options often exceed standard residential specs.
- Durability and environment: Industrial models include steel straps and rugged housings. HT-rated or weather-resistant variants suit harsher spaces or outdoor use.
- Wiring and installation: Some models require mating wiring modules or have line clamps pre-set for quicker wiring. Consider how the installation will fit into your panel or junction box.
- Protection features: Look for dual-function indicator lights, self-test functionality, and fault-clearing speed. Some designs perform self-tests more frequently to ensure continuous protection.
How to choose by settings and usage
- Home office and studio equipment: Prefer isolated ground options with self-test features for consistent protection of audio interfaces and computers.
- Workshops and garages: Industrial-grade models with wraparound steel straps provide durability under vibration and heavy use.
- Laboratories: Choose units with higher galvanic isolation and reliable fault handling to protect sensitive instruments.
Installation tips
- Read your circuit requirements and ensure the outlet matches amperage and voltage needs.
- Use appropriate wiring modules where required; some units require separate modules for proper function.
- Ensure the ground path is solid and that the receptacle is properly mounted to minimize interference.
FAQ
- What is an isolated ground GFCI receptacle? An outlet designed to isolate the grounding path to reduce interference for sensitive equipment, often paired with GFCI protection for safety.
- When should I use a 15A vs 20A isolated ground receptacle? Use 15A for typical lighting and standard devices; 20A is better for higher-demand circuits or equipment that draws more current.
- Are self-test features important? Yes, they help ensure continued protection by periodically verifying the outlet can trip on a ground fault.
- Do I need a separate wiring module for some models? Some models require a mating wiring module sold separately; check installation details before purchase.
- Can these be used outdoors? Some models have weather/tamper-resistant features; verify the product’s weather rating and enclosure requirements before outdoor installation.
- Which Leviton option is best for industrial environments? The GFTR2-IGO and 5362-IGE models are designed for hard-use settings with robust construction.
