Great tips everybody!

Here's one, that you may or may not be aware of, that might be of particular use when roughing-in multi-ganged switch boxes (I have a designer/architect that is fond of 4, 5, and even 6-ganged centralized switch bays).

Before drywall and paint, use a flag of White PVC electrical tape and a sharpie a to identify eacvh lead. Write down an abbreviated description, like "PWR IN", "PWR OUT", KIT CANS (kitchen cans), etc.

The reason for PVC tape is that paint and drywall mud will usually scrape right off, and the sharpie will pretty much hold no matter what.

If this isn't enough protection (For sloppy drywallers and painters), a bit of 2" wide blue masking tape over the boxes can easily be removed during finish work.

Thanks for your input, and please feel free to add to this thread. I'm sure we can all learn a little bit from this.

Thanks
