15A Tamper-Resistant Self-Test GFCI Outlet
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.
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.

TST15 — answered
Is the TST15 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 TST15 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.
Can I use the TST15 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.
