Leviton T8300-W – Frequently Asked Questions

1) Will a Leviton T8300 receptacle accept a regular 15-amp plug, or only 20-amp plugs?
The T8300 is a NEMA 5-20R device, and a 5-20R face takes both standard 15-amp (5-15P) plugs and 20-amp plugs with the sideways blade. That is why it gets used for general-purpose outlets on 20-amp branch circuits: one device covers office equipment, vacuums, and the shop tool with the T-blade cord.
2) Is the Leviton T8300 tamper-resistant, and does that satisfy a TR requirement in dwelling units?
Yes, it is a tamper-resistant device with spring-loaded internal shutters that block a single-prong insertion into the energized contacts. Shutters only open when both blades push in together. If your drawing or inspector calls for TR receptacles in occupied or child-accessible areas, this is the TR version of a heavy-duty 20-amp device rather than a standard one.
3) Can I put a Leviton T8300 20-amp receptacle on a 15-amp circuit?
No. The T8300 is rated 20A at 125V and its 5-20R face invites a 20-amp plug, so it belongs on a 20-amp branch circuit wired with 12 AWG. On a 15-amp circuit you would be advertising capacity the wiring cannot carry. For a 15-amp circuit, use a 15-amp tamper-resistant 5-15R device instead.
4) What colors does the Leviton T8300 tamper-resistant receptacle come in?
Three: white (T8300-W), ivory (T8300-I), and red (T8300-R). Red is the one property managers and facility electricians ask about, since red devices are conventionally used to identify emergency or generator-backed circuits. White and ivory match standard wallplates and trim on general-purpose outlets.
5) How many wires does the Leviton T8300 receptacle need, and does it have a ground?
It is a 3-wire, 2-pole device: hot, neutral, and equipment ground. The ground terminal and U-slot are part of the configuration, so it needs a grounding means in the box. If you are replacing an ungrounded two-wire outlet in older construction, you need to establish a ground path before this is a legitimate swap.
6) Is the T8300 a straight blade or twist-lock receptacle?
Straight blade. The contacts are the flat, push-straight-in type of a normal wall outlet, not a locking device you rotate to seat. If your equipment cord ends in a twist-lock plug, this will not accept it and you need an L5-20R locking receptacle instead.
7) Is the Leviton T8300 heavy enough for a commercial corridor or a school, or is it a residential-grade device?
It is built as a heavy-duty grade device for repeated plug insertion and removal, which is what separates it from a builder-grade residential receptacle in a high-cycle location. Corridors, classrooms, workshops, garages, and utility rooms are the sort of openings it is intended for, and the TR shutters cover the occupied-space requirement at the same time.
8) Does the Leviton T8300 provide GFCI or AFCI protection?
No. It is a straight-blade tamper-resistant receptacle only, with no ground-fault or arc-fault electronics and no test and reset buttons. Where a kitchen, bath, garage, or exterior location calls for GFCI, either feed it from a GFCI receptacle upstream or protect the circuit at the breaker.
9) Will a standard wallplate fit the Leviton T8300, or do I need a special cover?
Standard decora-style plates will not work. The T8300 has a smooth face in the conventional duplex receptacle shape, so it takes an ordinary duplex wallplate, the kind with two round-ended openings. Nothing special is required, and the same plate you have on the rest of the run will fit.
