Wire & Cable Acronyms: Making sense of the letters

Decorated letters

If you work anything like we do around here, you’ve probably gotten into the habit of using all the wire acronyms in the book, but may not have spent a ton of time reflecting on what they mean in a while.

Well, we opened up our old manuals again to refresh our memories, and thought we’d remind everyone else while we were at it.

Let’s test it out:

RHW: Rubber insulated, moisture resistant, good up to 75°C

USE-2: Underground Service Entrance wire that can stand wet environments up to 90°C

XHHW: Cross-linked polyethylene insulation, moisture resistant and good up to 90°C in dry environments
