1. INTRODUCTION
This specification covers the requirements for application of wire to MTA (Mass Termination Assembly) 156
Connectors. These requirements are applicable to hand or automatic machine application tools.
Specific wire and insulation ranges relative to the products covered in this specification are 26–18 AWG tin
plated solid, concentric fused stranded, and concentric stranded wire with standard PVC thermoplastic
insulation having a maximum insulation outside diameter of 2.41 mm [.095 in.] when terminated one position at
a time, or 1.78 mm [.070 in.] when mass terminating. Stranded wire configurations approved by Tyco
Electronics are 18 AWG 7, 16, and 19 stranded; 20 AWG 7, 10, and 19 stranded; 22–24 AWG 7, 10, and 19
stranded; and 26 AWG 7 stranded. Underwriters Laboratories (UL) Inc. UL1061 is the preferred wire for mass
termination use with UL1007 also being initially approved for single termination with all wire AWG.
Other wires evaluated and approved by Tyco Electronics are provided in the table in Figure 1. Wires approved
are specifically shown by UL wire style and wire AWG tested. Only wire AWGs specifically shown in the table
in Figure 2 for each UL style are approved by Tyco Electronics. Other wires should be submitted for formal
evaluation by Tyco Electronics prior to use to verify proper product function. For specific connector assembly
part numbers and wire sizes, contact the Product Information number at the bottom of this page.
When corresponding with Tyco Electronics Personnel, use the terminology provided in this specification to help
facilitate your inquiry for information. Basic terms and features of components are provided in Figure 1.

NOTE:
When selecting approved wire styles noted in this list, the MTA Application Specifications guidelines must be followed. Also, due to
wire variations in insulation wall thickness, hardness, and wire stranding, we would recommend evaluating the wire selected before
final application approval.
