8. 90A and 100A 1-pole breakers require an adjoining position be left unoccupied for thermal reasons.

9. Size protectors (fuses or circuit breakers) as required by the National Electric Code (NEC) and/or local codes.

Refer to the equipment ratings to assure current does not exceed:
Continuous Load (List 1) - 64% of protector rating
Maximum Load (List 2 - typically end of discharge) - 80% of protector rating.

10. Field-wired Conductors - Follow all National Electric Code (NEC) and local rules and regulations when making

field connections.

• Size field-wired conductors based on listed recommendations, National Electric Code (NEC) and/or local

codes based on 70°C ampacity.

• Insulation rating: 90°C minimum; 105°C (minimum) if internal to enclosed equipment cabinets.

11. Bonding Network - Suitable for installation as part of either

• Common Bonding Network (CBN)

• Isolated Bonding Network (IBN)

12. Facilities - Suitable for installation in

• Network Telecommunication Facilities

• Locations where the NEC applies

13. DC Return - Isolated DC Return (DC-I) or Common DC Return (DC-C)
