Answer
RHW Cable Insulation Temperature Rating
🔍 Understanding the RHW Designation
The insulation code RHW specifies the following properties of the cable:
- R — Rubber (or thermoset) insulation
- H — Heat resistant (rated for 75°C)
- W — Suitable for use in wet locations
🌡️ Maximum Operating Temperature
Based on electrical standards, RHW insulation is rated for a maximum operating temperature of:
75°C
🔄 Celsius to Fahrenheit Conversion
Using the standard temperature conversion formula:
°F = (°C × 9 / 5) + 32
Substituting the values:
°F = (75 × 9 / 5) + 32 = 135 + 32 = 167°F
✅ The maximum temperature rating for RHW cable insulation is 167°F
