Equipment Wiring Terminals for Use with Aluminum and/or Copper Conductors
UL 486E
1 Scope

1.1 This Standard applies to equipment wiring terminals for use with all alloys of copper, aluminum, or copper-clad aluminum conductors, in accordance with the National Electrical Code, ANSI/NFPA 70, as follows:

• a) equipment wiring terminals intended to hold one or more conductor(s);
• b) equipment wiring terminals intended for use in appliances and equipment that comply with the requirements for such appliances and equipment;
• c) ampere-rated equipment wiring terminals;
• d) horsepower rated equipment wiring terminals; and
• e) wire range rated equipment wiring terminals.

1.2 These requirements apply to field wired equipment wiring terminals which are an integral part of the equipment, or are intended for use in specific equipment.

1.3 This Standard is intended for equipment wiring terminals suitable for use with conductors in the size ranges as follows:

• a) Aluminum
  1) 12 AWG (3.3 mm2) and 10 AWG (5.3 mm2) solid; and
  2) 12 AWG (3.3 mm2) to 2 000 kcmil (1 010 mm2) stranded, Class B concentric, compressed, and compact.
• b) Copper-Clad Aluminum
  1) 12 AWG (3.3 mm2) and 10 AWG (5.3 mm2) solid; and
  2) 12 AWG (3.3 mm2) to 2 000 kcmil (1 010 mm2) stranded, Class B concentric.
• c) Copper
  1) 30 AWG (0.05 mm2) to 10 AWG (5.3 mm2) solid; and
  2) 30 AWG (0.05 mm2) to 2 000 kcmil (1 010 mm2) stranded, Class B concentric and compressed, and Class C concentric.
• d) Compact-stranded copper conductors for 2 AWG (33.6 mm2) and larger.
• e) Rigid (solid and stranded) metric wire falling within the ranges of the above AWG sizes.
• Note: For example, an equipment wiring terminal rated for 6 AWG – 250 kcmil may be additionally rated for 16 – 120 mm2.
• f) Other class and strand configurations as indicated by marking.

1.4 This Standard is intended for equipment wiring terminals suitable for currents not exceeding the ampacity of insulated conductors rated 75°C or 90°C in accordance with the rating of the equipment wiring terminal, if provided.

1.5 This Standard does not apply to:

• a) insulated equipment wiring terminals; and
• b) wire binding screw terminals.
