Panel Lug Wire Range
Panel Lug Wire Range lookup table with assumptions and boundary notes.
Scope
Panel lug marking planning only. It does not approve conductor termination, torque, parallel conductors, or conductor size.
Lookup table
Decode common panel lug markings by conductor material, temperature marking, and wire-range label context.
Scroll sideways to keep row labels aligned with hidden columns.
| Lug marking | Conductor material | Temp lookup (C) | Wire-range context | Boundary |
|---|---|---|---|---|
| CU | copper conductor only | 75 | copper-only lug marking lookup | lug label planning only; wire range, torque, and conductor preparation come from equipment markings |
| AL | aluminum conductor only | 75 | aluminum-only lug marking lookup | lug label planning only; wire range, torque, and conductor preparation come from equipment markings |
| CU/AL | copper or aluminum conductor | 75 | dual-rated lug marking lookup | lug label planning only; wire range, torque, and conductor preparation come from equipment markings |
| AL7CU | aluminum or copper conductor | 75 | 75 C lug marking lookup | lug label planning only; wire range, torque, and conductor preparation come from equipment markings |
| AL9CU | aluminum or copper conductor | 90 | 90 C lug marking lookup | lug label planning only; wire range, torque, and conductor preparation come from equipment markings |
Notes
- Check table values for preliminary lookup and arithmetic checks only.
- Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
