Reply to comment by Vyzantinist in Attaching TV wall mount - how to avoid electrical wiring in the walls? by Vyzantinist

Yes, but there aren't that many wires in your wall, and chances of hitting one are close to zero if you're trying to hit studs to hang a TV mount. Diagram

Figure you have 3/8" drywall on 2x4 studs... The electrician would have put any wires halfway back on the stud or further - so your lag screw would have to penetrate the wall 1 5/8" just to reach where a wire might be, and pierce layers of plastic and paper protective sheathing perfectly to cause a problem. And IF there was a problem, the breaker would trip before causing any real harm.

Nail plates are only required if the hole drilled through the stud is closer than 1 1/4" from the face of the stud. So if it's a hole for one wire and it's centered on the stud, there won't be a plate.

Assuming there's no plate, a screw that is shorter than 1 3/4" won't hit the wire, but in this case OP is talking about a wall mount which likely has longer hardware. You'd be very unlucky to catch a wire, but it's not impossible.
