Should new wiring be protected from damage prior to drywalling?

Inspector allowed me to install switches & receptacles prior to rough inspection (which was passed). Have tested everything and it works. Now, contractor wants me to pull all these before drywalling. Says leaving them in place will slow the work and might cause damage to wires. Question: If they're going to cut openings with keyhole saws after slapping walls up, isn't there a real risk of damage to the exposed wires & what can be done in advance to protect them? Thanks.

Hate to tell you but your contractor is right, plugs never go on before the drywall, mainly because they don't want to be responsible for any damge that may occur.

If you can convince them to do it with them on you will have to remove the devices from the box and they will have to cut the holes in the drywall first, Then they will pull the devices through the cutouts as they put up the sheets. After they do this I would recommoned taking some poly and wrapping every plug and switch for it does not get covered in mud when they come into tape.

Most of the cutting will be done with routers. Remove the devices and push the wires as far back into the boxes as possible.

Thanks darren and brric. Don't mind pulling these. Should take hour or less and can label wire ends. Maybe should let the pros do their job and not worry. However, some pretty crowded boxes, and would be willing to do whatever recommended if further protection needed.

In addition to pushing the wires back as far as possible in the box, you might want to consider filling them with newspaper. I learned this the hard way after wiring my first house. After cutting out the boxes, the drywaller sprayed the texture and primer. Every wire had a nice coat of primer afterwards.
Some advice you receive on the internet can be worth exactly what you paid for it - be careful.

Wow first time I hear of this, guess it makes sense. Good to know. I always figured the plugs and switches would all go in first so they can be properly tested, and you just put painters tape on the holes to prevent dust from getting in while drywalling.

Great tip on the newspapers.

Basement is almost ready for plastering , messier yet for boxes.

I learn something useful here every day.
