20A Self-Test GFCI Outlet (Non-TR)
20A 125V ground-fault receptacle with a NEMA 5-20R face. It is built as a Class A self-test GFCI — the device checks its own protection circuit and locks out the reset if that check fails.
Part of the Class A self-test GFCI line — UL 943 Ed. 6 construction, 5 mA ±1 mA trip level, automatic self-test with reset lockout on failure.

- Confirm TR or non-TR before ordering — NEC 406.12 applies to dwelling units and public spaces.
- On WR models the receptacle is half the assembly: the cover and the box are separate lines.
- GFCI + USB models take a decorator opening and a deeper wall box — confirm the box before the order.
- Automatic periodic self-test verifies protection with lockout on failure
- UL/cUL listed under UL 943, Class A: trips at 5mA ±1mA
- Non-TR face: for applications not requiring tamper-resistant construction under NEC 406.12
- NEMA 5-20R configuration with back-wire and side-wire terminal options
- 7 standard colors — White, Black, Ivory, Almond, Grey, Brown, Graphite
- Wall plate included

Use this one, or step to another
- Contractors sourcing a 20A GFCI replacement with a NEMA 5-20R face
- Distributors building out 20A indoor GFCI inventory
- Facility and MRO buyers who need a clearly identified 20A self-test model
- Procurement teams comparing 15A vs 20A GFCI device formats for project use
- Choose a 15A self-test GFCI outlet if the project calls for a standard 15A face instead of NEMA 5-20R TS15 — 15A Non-Tamper Resistant Self-Test GFCI Receptacle
- Choose a TR GFCI receptacle if the installation location requires tamper-resistant construction under the applicable code scope TST15 — 15A Tamper-Resistant Self-Test GFCI Outlet
- Choose a WR GFCI receptacle if the installation environment requires a weather-resistant device WTST20 — 20A Weather-Resistant Self-Test GFCI Receptacle
- Choose a USB GFCI receptacle if the project also needs integrated device charging UWTST15 — 15A Combination USB GFCI Receptacle with Dual USB-A

How to Install a 20A GFCI Outlet
The plate for this device is T9603 1-Gang Decorator Receptacle Wallplate. Order the plate with the device so the opening, the face and the finish arrive on the same delivery — and confirm the wall box depth on any combination or fast-charge model before installation day.

TS20 — answered
Is the TS20 a self-test device, or do I have to test it myself?
Every model in this line is self-test. The device runs an automatic periodic check of its own protection circuit and, if that check fails, locks out the reset — so a failed GFCI cannot be reset and left in service. On the UL 943 framework the self-test is a requirement, not an upgrade, and it removes the monthly manual test that nobody in a guest room or a rental ever performs.
Where is a non-TR device still acceptable?
Outside the occupancies listed in NEC 406.12 — in practice commercial maintenance areas, mechanical and utility rooms, industrial spaces and like-for-like replacement of existing non-TR devices in locations the code does not cover. Verify against the NEC edition your AHJ has adopted; if the project type is unclear we quote the TR configuration and flag the assumption in writing.
Can I use the TS20 outdoors or on a covered porch?
No. This model is not weather-resistant and is published for indoor dry locations. For exterior walls, patios, pool and irrigation equipment or a garage with direct weather exposure, order the WR model in the same line and pair it with the correct cover.
Does it come with the wall plate and the screws?
Yes — wall plate included, and the matching plate for this face is T9603 1-Gang Decorator Receptacle Wallplate. Mounting screws ship with the device. If you need plates packed separately for a distributor program, that is a packaging instruction on the order rather than a second purchase.
Can a 15A device go on a 20A circuit?
A 15A receptacle is permitted on a 20A branch circuit where the circuit serves two or more receptacles — that is NEC 210.21(B)(3), and it is normal practice in commercial and multi-unit work. What is not interchangeable is the face geometry: a NEMA 5-20R device on a 15A circuit fails the same inspection the other way round. Confirm the circuit design rather than the look of the device.
Does the GFCI protect the outlets downstream on the same circuit?
Yes, when the LOAD terminals are used: the hot and neutral feeding the downstream devices land on the brass and silver LOAD terminals and everything beyond them is protected by this device. Reversing LINE and LOAD is the error that shows up as a GFCI that trips as soon as a downstream load is plugged in — and it silently removes the downstream protection as well.
