Installing Receptacle Boxes

I'm in the process of installing electrical boxes and was wondering how you know where to set the box for sheetrock thats 5/8 rather than 1/2"? The boxes that I got have a marking for 1/2" only. Is it ok to set to that mark or will the boxes be too recessed? This is new construction BTW.

Boxes can only be 1/4" back from non-combustible material. Just use a tape measure or a scrap piece of wood/drywall to set your boxes at the proper depth.

You're allowed 1/4", not 1/8" (5/8 is 1/8 bigger than 1/2 anyway).. So technically he'd be fine setting them at 1/2" as long as the holes were cut neatly so the device yokes are supported by the sheetrock...

I use the scrap material to space the boxes. There may also be a thin line already on the box for both 3/8" and 5/8" rock.
