Yes, we see it done (or attempted) a bunch of times in each of the various series. I've selected an example from each: Enterprise ---------- In [Ent: United][1], Tucker sets a phase pistol to overload inside a wall panel. It causes substantial damage. [![enter image description here][2]][2] DS9 --- IN [DS9: Empok Nor][3], O'Brien uses his combadge to signal a phaser to overload. It explodes and causes a substantial diversion. [![enter image description here][4]][4] TNG --- In [TNG: The Hunted][5], Danar sets two phasers to overload. One in the turbolift (which Worf averts) and another inside a security panel which then explodes. [![.][6]][6] Voyager ------- This one's a bit tricky. In [Voy: Worst Case Scenario][7], we see a phaser set to overload but in a way that causes a backfire.
