#diy #tools #organization I often have a need to label wires and cables. Anything from 18ga hookup wire in electronics to thermostat wire to 14/12/10/8ga electrical wire to HDMI cables, and more. I've long advocated for Dymo labels like my trusty old Rhino 4200 in combination with inexpensive generic label cartridges. I recently was shown how nice the heat shrink labels are which DON'T FALL OFF(!!!). ![[Pasted image 20240516121948.png]] These are available in "black on white" and "black on yellow" in 1/4" (6mm), 3/8" (9mm), 1/2" (12mm), and 3/4" (19mm) nominal sizes. The size listed is the FLATTENED width. Dymo lists these as a 3:1 shrink ratio. I've had good luck with the "Aonomi" brand of generics on Amazon. ## 1/4" Wide *This is a good size for very small wire: as small as 22 gauge hookup wire, and as large as #12 THHN (snug fit on).* Diameter (unshrunk) = 3.8mm Diameter (maximum shrink) = ~1.3mm (6mm * 2 = 12mm circumference / 2pi = 1.9mm radius) White = DYMO 18051 Yellow = DYMO 18052 ## 3/8" Wide *This works well on a variety of wire sizes: as small as #14 THHN, and as large as #10 THHN.* Diameter (unshrunk) = 5.7mm Diameter (maximum shrink) = ~1.9mm White = DYMO 18053 Yellow = DYMO 18054 ## 1/2" Wide Diameter (unshrunk) = ~7.6 Diameter (maximum shrink) = ~2.5 mm White = DYMO 18055 Yellow = DYMO 18056 ## 3/4" Wide *This fits well over 10/2, 12/2, 12/3 NM-B (Romex). Probably 10/3, but untested.* Diameter (unshrunk) = ~12.1 mm Diameter (maximum shrink) = ~4.0 mm White = DYMO 18057 Yellow = DYMO 18058 ## Common Wire and Cable Diameters | Type | Diameter (mm) | | ------------------------------- | ------------- | | #14 THHN Stranded | 3.0 | | #12 THHN Stranded | 3.6 | | #10 THHN Stranded | 4.3 | | #8 THHN | 5.9 | | #6 THHN | 6.4 | | #4 THHN | 8.4 | | #3 THHN | 9.1 | | #2 THHN | 9.9 | | #1 THHN | 11.4 | | 1/0 THHN | 12.7 | | 2/0 THHN | 13.7 | | 3/0 THHN | 15.3 | | 4/0 THHN | 16.8 | | 12/2 MC | 12.3 | | 18/5 Solid Thermostat Cable | 4.5 | | CAT6A | 5.8 | | 22 gauge hookup wire (stranded) | 1.5 | | 12/2 NM-B (Romex) | ~4.3 x 10.2mm |
