Equipment Rated for 100 A or Less — NEC 110.14(C)(1)(a) items 1 through 4:
For equipment with termination provisions for circuits rated 100 A or less or marked for 14 AWG through 1 AWG conductors, the NEC allows conductors to be used based on the following four conditions:
- Conductors rated for 60°C.
- Conductors with higher temperature ratings can be used, but their ampacity must be based on the 60°C rating.
- Conductors with higher temperature ratings are allowed if the equipment is listed and identified for use with those conductors.
Equipment Rated above 100 A — NEC 110.14(C)(1)(b) items 1 and 2
For equipment with termination provisions for circuits rated above 100 A or marked for conductors larger than 1 AWG, the NEC 110.14(C)(1)(b) items 1 and 2 allow conductors to be used based on the following conditions:
- Conductors rated 75°C
- Conductors with higher than 75°C can be used, but their ampacity must be based on the 75°C rating.
