APPLICATION GUIDELINE FOR TERMINAL BLOCKS

NEMA - National Electrical Manufacturers Association

Abstract: This standard applies to one piece, or modular, or two piece terminal blocks with screw-type or screw-less-type clamping units intended for industrial use, and fixed to a support or to a Printed Circuit Board (PCB) to provide electrical and mechanical connection for the following round, solid, or stranded conductors:
a. Copper conductors only, without special preparation, having a cross section of 24 AWG to 2000 kcmil (0.2 to 1014 mm²), or 30 AWG to 8 AWG (0.05 to 8.37 mm²) for Printed Circuit Board (PCB) terminal blocks.
b. Aluminum (uncoated) conductors only, without special preparation, having a cross section of 12 AWG to 6 AWG (2.5 to 16 mm²) for solid conductors and of 12 AWG to 2000 kcmil (3.3 to 1014 mm²) for stranded conductors.
c. Aluminum (uncoated) and copper conductors, without special preparation, having a cross section of 12 AWG to 6 AWG (2.5 to 16 mm²) for solid conductors and of 12 AWG to 2000 kcmil (3.3 to 1014 mm²) for stranded conductors.
The terminal blocks are intended for use in circuits of rated insulation voltage not exceeding 1000 V AC at a frequency not greater than 60 hertz, or not exceeding 1500 V DC.
This standard does not apply to connectors specifically designed for, and forming, an integral part of equipment, which are dealt with in the relevant equipment standards.
NOTE This standard may be used as a guide for the termination requirements for disconnect type or other special terminal blocks for which there is no standard at this time.
