+ —1. What is the maximum current rating? >
- The rated current is 45A, with 8 AWG wire requiring 26 in-lbs torque for optimal contact.
-
+ —2. Is it suitable for outdoor use? >
- While the material is moisture-resistant, outdoor installations need waterproof enclosures.
-
+ —3. Can over-tightening damage the terminals? >
- Follow torque specs: 20 in-lbs for 10-14 AWG, 26 in-lbs for 8 AWG, to prevent deformation.
-
+ —4. Does it support voltages above 600V? >
- No, exceeding 600V violates safety ratings and may cause breakdown.
