15A Weather-Resistant Self-Test GFCI Receptacle
15A 125V ground-fault receptacle with a NEMA 5-15R 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. The face is tamper-resistant, so the shutters stay closed unless both slots are pressed at once. The body carries the weather-resistant construction for damp and wet locations — the cover is a separate line item.
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 self-test monitoring helps verify GFCI protection status
- UL/cUL listed under the UL 943 Class A GFCI framework with a 5mA ±1mA trip level
- WR and TR construction supports outdoor and public-facing applications that require both weather resistance and tamper-resistant protection
- Standard 15A receptacle configuration with contractor-oriented installation use
- 7 standard colors — White, Black, Ivory, Almond, Grey, Brown, Graphite
- Use with a listed extra-duty in-use cover where required for wet locations

- Property management buyers handling apartment and condo exterior upgrades
- Project buyers who need a standard 15A outdoor GFCI rather than a 20A T-slot device
- Choose a 20A WR GFCI receptacle when the project requires a NEMA 5-20R / 20A device format rather than a standard 15A receptacle. WTST20 — 20A Weather-Resistant Self-Test GFCI Receptacle
- Choose an indoor TR GFCI receptacle when the installation does not require weather-resistant construction. TST15 — 15A Tamper-Resistant Self-Test GFCI Outlet
- Choose a non-TR WR GFCI receptacle only when the installation location does not fall within the tamper-resistant receptacle requirements that apply to specified 15A and 20A nonlocking receptacle locations. TS15 — 15A Non-Tamper Resistant Self-Test GFCI Receptacle

How to Install a 15A WR GFCI Receptacle
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.

WTST15 — answered
Is the WTST15 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.
Why does the WTST15 feel tighter when I push a plug in?
Because it is tamper-resistant. The shutters stay closed unless both slots are pressed at the same time, which is what makes a TR receptacle feel firmer than a standard outlet. NEC 406.12 requires listed TR receptacles in dwelling units, guest rooms, education and child-care facilities and similar occupancies — the tightness is the feature, not a defect.
Is WTST15 waterproof?
It is weather-resistant, not waterproof. The WR construction covers the device itself for the damp and wet locations described in NEC 406.9, and the device is only half of that assembly — the cover and the box are separate line items. Ordering the WR rating without the cover is the most common way a damp-location install fails inspection.
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.
What do you need from me to quote a mixed order?
The model list with quantities, the project type, the colour and the plate schedule. The quotation comes back in one business day with the specification sheet for each line item, the listing reference it holds and the packing detail for the DC — one document rather than four.
