2 / 8 page 408-2433 Insulation Piercing COPALUM Terminal and Splice Crimping Heads Rev A 2 of 8 Tyco Electronics Corporation Conductors must always be within CMA limits of wire barrel. A. Condition 1 See Figure 2, Detail A Maximum CMA fill for copper conductor should not exceed 40% of total CMA. For example, six No. 14 solid aluminum 12.14 mm2 [24,000] Cir Mil plus one No. 8 stranded copper 8.10 mm2 [16,000] Cir Mil equals 40,000 Cir Mil. The one No. 8 stranded copper conductor is approximately 40% of total CMA 20.24 mm2 [40,000] Cir Mil being crimped. Figure 2 Wire Barrel AB C DE Six No. 14 Sol. Aluminum: 12.14 mm2 [24,000] Cir Mil One No. 8 Str. Copper: 8.10 mm2 [16,000] Cir Mil (Not to Exceed 40% of Total CMA) Round Copper or Aluminum (10 Equal Size) Square Copper or Aluminum (6 Equal Size) T W T W T 1/4 W T 1/4 W 10.52 mm2 [20,800] Cir Mil Area - Circular Mils Terminal and Splice Sizes 6.07 mm2 [12,000] Cir Mils = 59% Load ing of 10.52 mm2 [20,800] Cir Mils B. Condition 2 See Figure 2, Detail B A maximum of ten equal size round conductors may be crimped without removing film insulation. C. Condition 3 See Figure 2, Detail C A maximum of six equal size square conductors may be crimped without removing film insulation. D. Condition 4 See Figure 2, Detail D Four identical rectangular conductors, where one conductor thickness is equal to or greater than 1/4 the width of one conductor, may be crimped without removing film insulation. E. Condition 5 See Figure 2, Detail E Two identical rectangular conductors, where thickness of one conductor is equal to or less than 1/4 of the width of one conductor, may be crimped without removing film insulation. F. Condition 6 See Figure 2, Detail F In some instances, it may not be possible to fit a particular CMA loading into the normally recommended terminal or splice. In these cases, where seven or more equal round, or a combination of solid aluminum and stranded copper conductors are used, and the total CMA is at least 50% of maximum CMA of the next larger size terminal or splice, the larger size may be used. Example: three No. 14 solid conductors equal about 6.07 mm2 [12,000] Cir Mils. This falls within the CMA range of a 12–10 terminal or splice accepting a maximum CMA of 6.63 mm2 [13,100] circular mils. However, it may not be possible to insert all three conductors into the recommended terminal or splice. It is possible to insert all three conductors into a No. 8 size terminal or splice accepting a CMA range of 6.63–10.52 mm2 [13,100–20,800] circular mils. The 6.07 mm2 [12,000] circular mils amounts to 59% loading of the maximum CMA for No. 8 size terminal or splices. Therefore, No. 8 size terminals or splices may be used. G. Condition 7 When using a variety of solid conductor sizes, none of the conductors should vary more than one (1) wire gage. (Ideally not more than 1/2 wire gage.) 2.4. Wire Preparation Do not use stranded aluminum wire. 1. Select the proper terminal or splice wire size and crimping head combination for the wire size being used. See Figure 3. 2. Determine correct terminal or splice wire loading by referring to Paragraph 2.3, and CMA range listed in Figure 3. 3. Strip stranded copper wire to dimension indicated in Figure 3. NOTE i NOTE i |
