Leviton T5320-WMP: The Tamper-Resistant Outlet That Actually Earns Its Keep

The Leviton T5320-WMP gives you 10 tamper-resistant duplex outlets rated for 15 amps at 125 volts. Each outlet features both quickwire push-in terminals and traditional side-wire screws, wrapped in an ultrasonic-welded thermoplastic housing that handles temperatures from -40°C to 60°C.

Worth it for contractors doing residential work where code compliance matters. The TR shutters prevent kids from jamming keys or hairpins into the slots, and that TR symbol on the face proves NEC 2008+ compliance at inspection. At 4.7 out of 5 stars across nearly 10,000 reviews on Amazon and Home Depot, electricians have voted with their wallets.

Skip it if you’re doing basic shop wiring where tamper resistance adds cost without benefit. Standard non-TR outlets cost less and work fine where child safety isn’t a concern.

Installation Flexibility That Saves Time on the Job

The dual termination system accepts 14 AWG solid copper in the quickwire push-in terminals, while the side-wire screws handle both 14 and 12 AWG. That flexibility matters when you’re mixing wire gauges in a remodel or dealing with whatever the last guy left in the box.

The shallow profile maximizes wiring room in crowded boxes. Every electrician knows that dance — trying to fold wires back without breaking connections while the device won’t seat flush. Leviton shaved enough depth here to make a difference, though some users still find it tight with thick 12 AWG runs in overcrowded boxes.

The push-in terminals work exactly as advertised for 14 AWG solid copper. Strip to the gauge mark, push straight in, done. No wrapping screws, no checking torque specs. But here’s the thing — quickwire only accepts 14 AWG solid copper. Got stranded wire or 12 AWG? You’re back to the side screws.

Built for Montana’s Temperature Swings

The -40°C to 60°C operating range covers everything Montana throws at buildings. That matters more than you’d think. Outlets in unheated garages, shops, and crawl spaces see temperature extremes that crack cheap plastic housings. The impact-resistant thermoplastic nylon construction and ultrasonic welding create a housing that won’t split when temperatures plummet.

The V-2 flammability rating meets code requirements without going overboard. You’re not paying for V-0 aerospace specs you don’t need in residential work.

Where These Outlets Shine (And Where They Don’t)

These work perfectly in residential new construction and retrofits, schools, daycare facilities, and any commercial space where NEC requires tamper resistance. The 10-pack format makes sense for production builders cranking out tract homes or apartment complexes where every outlet needs TR protection.

The self-grounding brass clip speeds installation when you’ve got proper metal boxes. No pigtailing ground wires to the device — the clip handles continuity through the mounting strap. The heavy-gauge steel mounting strap won’t bend when you’re torquing it down to a warped box.

What’s missing? Wallplates aren’t included. And while users praise the 10-pack format, you’re committed to white. No almond or ivory options if the homeowner changes their mind mid-project.

Professional Consensus

Contractors praise ease of installation and the effectiveness of the safety shutters across nearly 10,000 combined reviews. These aren’t fancy smart outlets or USB-equipped models. They’re workmanlike 15-amp receptacles that meet code, install quickly, and hold up over time.

The shallow profile addresses a real jobsite problem. The dual wiring options provide flexibility without compromising connection quality. The -40°C rating handles Montana winters. And those UL, CSA, and NOM certifications mean you won’t have inspection issues.

Leviton backs these with a 2-year limited warranty covering materials and workmanship defects. That’s not industry-leading, but it’s sufficient for a mechanical device with no electronics.

The Verdict

The T5320-WMP delivers what contractors need: code-compliant TR protection, flexible installation options, and durability. The shallow design that maximizes box space solves a real problem. The quickwire option for 14 AWG saves time on big jobs.

These aren’t revolutionary. But sometimes you just need outlets that install fast, meet code, and don’t generate callbacks. The T5320-WMP handles that assignment.

Frequently Asked Questions

Can quickwire terminals be used with 12 AWG wire? No. Quickwire push-in terminals accept 14 AWG solid copper only. For 12 AWG wire, use the side-wire screw terminals.

Do these outlets require a special wallplate? These fit standard 5-15R duplex wallplates. Wallplates are sold separately.

What’s the actual temperature rating? These outlets operate from -40°C to 60°C (-40°F to 140°F). That covers any installation location in Montana, from unheated garages to attics.

Are these suitable for outdoor installation? The outlets themselves aren’t weather-resistant. For outdoor use, install them in a weatherproof box with an in-use cover.

How do the tamper-resistant shutters work? The TR shutters prevent insertion of foreign objects like keys or hairpins. Both slots must be pressed simultaneously with equal pressure — like from a proper plug — for the shutters to open.
