[RE-wrenches] Label Durability

[Dave Angelini Offgrid Solar]

If there was something available like a sharpie with acrylic latex I
would use it more. Just easier to put it in the JB and know it will last.
As far as code, I just do what the inspector wants. Luckily I do not see
them much

the mistake of writing the "start date" for the test wall in Sharpie, but I
think it only lasted the first couple years. As others have pointed out,
the ink will usually fade and become illegible within a few years -
depending on the level of direct sunlight exposure. I've got plenty of
photos from site re-visits showing labels with handwritten numbers that are
no longer visible. As Martin pointed out, it's questionable whether labels
can even include handwritten text based on NEC 110.21(B)(2)... So, I guess
in response to your follow-up comment, feel free to show those folks this
photo along with the message "here is your sharpie" (it's completely
vanished).   We experimented with nylon labelmaker tape and found that to
generally hold up better than Sharpie. We also tried out a handheld
engraving tool (for plastic/phenolic labels), but that was kind of a
non-starter. At one point we even invested in a full-fledged engraving
machine. I believe it came with its own software, and we purchased sheets
of blank placard material. Unfortunately, we could never get our machine
operator to turn the corner on making the label creation process efficient

Did you use a sharpie
on the box? I wonder how a sharpie or PICA marker would hold up for 10
years. 

 It's an awesome test though. I love it.
