I get asked quite a bit how I label my wires and finally got around to an answer. I did not always use this technique and over the years have tried lots of "solutions" before settling on a solution that both works for me and seems to last in the marine environment.
For me I have found that a simple Brother P-Touch label maker from Staples works wonders. These label makers often go on-sale for $9.99 to $20.00. Even for teh one pictured I paid just $19.99 plus the TZ tape. Using a P-Touch is not however without some tricks and techniques, which I will explain.
In order to use a Brother P-Touch you will want to invest in their TZ label tapes shown in this photo. they come in many colors but black letters on white tape seems to work best. These tapes do not turn black when you heat shrink over them like the cheaper Brother tapes do. The cheaper labels will turn black once you hit them with a heat gun but the TZ labels survive, provided you don't go over the top with your heat gun.
