Hi Everyone.

Just wondered what different methods people use to label their cables/wires so you know what which wire does what. Sometimes I find colour coding isn't sufficient and it's good to have some labels indicating the purpose of a wire. I was thinking about just using white sticky labels but wasn't sure if there were any better methods being used by anyone else.

go to an electrical supply house, they have numbers and letters in little rolls, adhiesive backed that are used for marking wires and cables. there are also tyewraps available with "flags" that can be written on to mark cables.
I use color coded wire, orange for +5, red for +12, and such for wireing inside projects, takes up less space.

Depends on the size of the project, there are standard industrial labels available that you clip on wires, there is the DYMO label printer which is quite useful but not a very cheap investment, or as you noted you can use your own stickers but those might not stand very well to old age, dust, weather etc.

+1 on T+B markers. My two favorites are the rolls/sheets of preprinted number/letters and the laser printable labels. Good stuff.

I would caution against use of a normal tape label printer, such as those made by Casio, Brother, etc., if the wires must be in a hot environment. We used this type of labeler for test configurations in the computer room, and it worked well in the controlled environment. When I tried to use the same in our attic, the labels peeled off in the summer heat.

I have used a few methods. The pre-printed numbers and letters are nice, but then you have to keep an index or log for them. Masking tape gets either dry or gooey. Last year I tried ZipTape Rite&Wrap:

Each marker label has a white area you can write on -- ball point, marker, soft pencil. For the 3/4" x 1-1/4" label, the writing area is 3/4" x 5/16" . The tail is clear. You then wrap it around the wire. with the tail going around last. That gives protection to the writing. The back of the white area also has adhesive, so you can put them on as flags. They have been on wiring for my furnace for about a year, have not gotten gooey or hard, and are readable. They do stick tightly, so getting them off without a #11 blade can be hard, unless you have good fingernails.

Here's a link to one of several American vendors. I believe Amazon and regular electronic parts houses sell them too. http://www.markertek.com/product/zt-rwd-51/ziptape-rwd-51-rite-wrap-wire-marker-dispenser-51?utm_medium=shoppingengine&utm_source=googlebase&utm_source=google&utm_term=Product_Target&utm_campaign=Shopping+-+Cable+Management&utm_medium=cpc&utm_content=w1wzR35y|pcrid|74923782140|pdv|c|&gclid=CIfhwL3Q2coCFYVAaQodJ1IAxQ

Another alternative is little PVC numbered "cuffs". They are extruded and wound on a reel like wire, but sliced part way through so you can just twist one off the end when you need it. There are various types, some are stretchy enough to suit a range of diameters while others have gussets and can accommodate more diameters.

Some are colour coded as well as numbered.

The wire cutter/stripper we use also has a laser writer that literally writes any text you desire at any increment along the wire.

That's what we use at work, can you tell we do a lot of hand wiring jobs?

When still working, at Delphi/Packard, they used engraved wheels with a concave edge to print on the wires. This was spark plug wire though.
