What does Rhw mean on wire?
For example, in the case of “RHW,” the “R” stands for rubber or neoprene outer insulation, the “H” stands for a heat resistance of 75 degrees Celsius (it would be “HH” for 90 degrees Celsius) and the “W” stands for the ability of the wire to withstand water damage.

USE-2 can be used as RHW-2 or RHH cable at temperatures up to 90°C in wet or dry locations. What does the “-2” stand for? It is a designation used for the 90° C temperature rating. In the past, there was a plain USE, but it is now generally considered obsolete and replaced by USE-2.
What is difference between XHHW and XHHW-2?
THHN/THWN-2 is a thermoplastic product, while XHHW-2 features thermoset insulation….HOW TO KNOW THE DIFFERENCE.
| THHN/THWN-2: | XHHW-2: |
|---|---|
| T = Thermoplastic | X = Cross-Linked Polyethylene (XLPE) |
| HH = High Heat Resistant | HH = High Heat Resistant |
| W = Water Resistant | W = Water Resistant |
| N = Nylon Jacket | (Not Required) |
What does RHH or RHW mean?
RHW wires are an underground service entrance cable for direct burial in which the conductor temperature will not exceed 90 degrees Celsius wet or dry. RHW-2/USE-2 and RHH cables have a voltage rating of 600 volts and are high-heat, moisture, and sunlight resistant.
