Why Your Leviton DZ15S Switch Keeps Tripping Power

You flip on your Leviton DZ15S smart switch, expecting a glow of light or a hum of appliances, but—click—darkness strikes again. Your high-tech Decora Z-Wave switch is tripping power like a moody gatekeeper, and you’re left fumbling in the shadows.

The Shock of a Tripping Leviton DZ15S

It’s a quiet evening, you’re settling in with a book, and you tap your Leviton DZ15S switch—a sleek, Z-Wave wonder meant to make life smarter. But when it keeps tripping power, that futuristic dream fizzles into a frustrating blackout. This 15-amp marvel—built for lights, fans, and small appliances—shouldn’t play power police every time you use it. Overload? Wiring gremlins? App glitch? A tripping switch isn’t just inconvenient—it’s an electrical enigma begging for a spark of clarity. Let’s hunt down why your DZ15S is cutting the juice and flip it back to reliable brilliance—no more groping for candles.


Digging Into the Power Puzzle

Channel your inner electrician—count the load. What’s plugged in? Lights (100W) + fan (50W)—over 1800W (15A at 120V)? Overload’s the villain; your Leviton DZ15S self-protects. Trip instant? Short circuit—check outlets downstream (unplug all)—still trips? Wiring’s suspect—loose or frayed in the box (power off, cover off).

Delayed trip? Heat buildup—feel the switch; warm means resistance. Z-Wave glitch? App stuck—cycle power (breaker off/on), re-pair (press paddle 3x). Breaker upstream tripping too? Panel check—15A breaker match? Old wiring—aluminum or knob-and-tube? Each flicker or click’s a clue—trace the current.


Fixing the Trip Trap

Light it up—overload? Cut load—swap bulbs (LED, 10W each), unplug extras—test; steady glow wins. Short? Power off (breaker), open box (screwdriver)—tighten wires (white neutral, black hot), replace burnt (wire nuts, $2)—flip on. Heat issue? Swap switch (DZ15S, $40)—poor contact fries it.

Z-Wave off? Reset—hold paddle 7s, LED blinks, re-add to hub. Breaker mismatch? Upgrade (15A, $10)—electrician if unsure ($100). Old wiring? Pro inspection—aluminum needs fixes ($200+). Test—run 30 minutes; power holds, you’re the circuit savior; trips linger? Electrician for deep dive. Lights stay on—shock-free bliss.


Preventing Power Panics

Keep it live—tally watts; stay under 1440W (80% rule). Check wires yearly—loose loves chaos. Update hub firmware—glitches trip too. And breaker test—flip annually, stiff dies early. Your Leviton DZ15S should now shine steady. If your Lutron Caseta flickers, see this guide for flicker fixes.
