Drywallers and electrical boxes


When I had my RI inspection (I passed ) the inspector made a comment about using deep boxes on 2x4 walls that would have drywall on both sides. He said it is best to feed both cables through an outer box hole so they can be pulled to the center of the 2x4 for stapling - drywallers and their screw guns can miss the 2x4
I watched them put up some of the rock - they go pretty fast. If the screw misses, they just load another and move it a bit.
What nobody mentioned though was the "rotary saw" they use to cut the box holes. They partially hang the sheet, then plunge the saw into the box, then feel for the box edge and jump over it, and then trace the outside of the box by feel. I didn't know this is how it is done and some of the boxes didn't have the wires tucked way back and they nicked a few with that saw. I have the remaining wires tucked way back in the boxes.
They only covered up one recessed ceiling light
It has been interesting....

Welcome to residential construction.Every trade gets into a groove that makes the job sail smooth. All trades usually comply with each other to get a job done smoothly.

HA!

Sheetrockers are the WORST!!

Typically non-American speaking crews with NO regard for the other guy. They don't give a damn because once they are done they are gone.
The only ones that might care are smaller local guys that get repeat work. This way they can be back charged for screw-ups, or not get the next job.

I just can't wait to see how much joint compound gets into the boxes, but there aren't a lot of seams close to the boxes. They will be priming and painting one coat too....... How about stuffing newspaper into the boxes? Those plates would be OK if it was only a couple of rooms but a whole house?

I usually work within the same group of guys, where I wouldn't mind twice to let a tool or two out on the job.

If they cut the wires, their Rotozips were set incorrectly. The guard should be set so that the depth of the cutter part of the blade is no deeper than the thickness of the drywall. The tip of the blade is just a round piece of metal with no cutter, this is usually called the pilot point, this is what feels the outside of the box for tracing. This part of the blade is the only part that should protrude from the other side of the drywall. For safety sake you should always push the wires back as far as possible into the box, but in all honesty, I don't mind when they cut the wires. It's very apparent how the wires get cut and I make out like a bandit fishing new ones. The GC gets his due when he pays me to clean up after the hacks he hired to drywall in order to save a buck.

I've stuffed newspaper before and had decent luck. It doesn't save damage from the rotozip, but it keeps out the mud, texture, primer and paint - especially if it will be a spray job.

I found out the hard way after pulling my wires out of the box and noticing every one was primer white.

I don't know a dry-waller that uses a dept-gage on their cutout tool.
I have an electrical inspector that knows me, and I don't strip any wires until the drywall guys are done. That way they only nick the outer case of the romex.

Ask the inspector if he/she will let you do that.

I have had a drywaller cut the device mounting ear off a metal box before.

I have had them cut completely through the wires in a box.

The depth gauge is original equipment with all the Rotozip type tools. Anyone who knowingly takes it off and damages wires is 100% to blame. Back-charge baby.

I don't either but that doesn't mean they can willy nilly run the bit in 2 or 3 inches. If one is competent, they can use a roto zip without a depth gage and not cut the heck out of everything. It's called "paying attention to what you are doing" and having some respect for others work.
