Leviton 78003 – Frequently Asked Questions

1) Will a Leviton 78003 wallplate fit a standard single-gang duplex receptacle box?
Yes. The Leviton 78003 is a 1-gang plate with a single duplex receptacle opening, so it covers one standard duplex outlet in a single-gang box. It is a device-mount plate, meaning it screws to the receptacle itself rather than to the box or the wall, which pulls it flush over the device.
2) Can I use this Leviton white plate over a decora or rocker switch opening?
No. This one is cut for a duplex receptacle, the figure-eight opening with two round-shouldered halves. A decora, GFCI, or rocker switch needs a rectangular opening plate instead. A toggle switch needs a toggle-cut plate. Match the plate opening to the device face or it will not seat.
3) What is the difference between Leviton 78003-P and 88016-P duplex wallplates?
Both are white 1-gang duplex receptacle plates and they are ordered by model: 78003 and 88016. They are the two catalog numbers this white thermoset duplex plate is sold under, so specify the model number your job or standard calls out when you order.
4) Is thermoset a better wallplate material than nylon or standard plastic for a commercial building?
Thermoset is a cured, cross-linked plastic, so it does not soften with heat and it resists cracking and fading better than ordinary molded plastics. That matters in corridors, break rooms, and rental units where plates get hit and cleaned repeatedly. Nylon plates flex more and shrug off impact; thermoset holds its color and rigidity. For a white plate standardized across a property, thermoset is the usual commercial choice.
5) Will this white wallplate match the other Leviton plates already installed across my property?
If the existing plates are Leviton white, this will read as the same standard white finish, since Leviton holds one white across its wallplate lines. What can differ is sheen and texture between material families, so a thermoset plate set next to a smooth nylon plate on an adjacent wall may not look identical up close. For a uniform look on a fleet of units, standardize on the same model number, 78003 or 88016, throughout.
6) Is a device-mount wallplate okay when the receptacle sits recessed or proud of the drywall?
Device mount means the plate rides on the receptacle, not the wall, so if the device is set back too far behind the drywall the plate will tilt or leave a gap at the edges. Fix the device position first with a box extender or by adjusting the strap screws so the receptacle ears sit flush with the finished surface, then install the plate. That is the most common reason a new plate does not sit flat on a remodel.
7) Is this an outdoor or wet-location outlet cover?
No. This is a flat interior finish plate for dry indoor locations, residential and commercial. Outdoor receptacles, damp locations, and anything exposed to weather need a weatherproof in-use cover with a gasket and a hinged lid, not a flat thermoset plate.
8) Do I need to buy mounting screws separately for this Leviton duplex wallplate?
Wallplate screws normally ship with the plate, and on a device-mount duplex plate the single center screw threads into the receptacle's mounting strap. If you are replacing a plate only and reusing the existing receptacle, the original screw works fine. Keep in mind this plate does not include a receptacle, box, or ring: it is the finish cover only.
