[16] Some products may be discontinued. Refer to www.se.com/us for the most current product information. [17] These maximum current values assume the use of insulated copper conductors with 167 o F (75 o C) temperature rating and are calculated based on NEC Article 310, Table 310-16. In most cases this value is the maximum ampacity of the wire which has the greatest current carrying capacity. The actual allowable current for a particular application depends on the size, insulation class, and other characteristics of the wire used. The UL ratings are shown. The CSA rating may be higher or lower. Refer to the catalog for CSA ratings. [18] One end-barrier is required for each assembly of like blocks. [19] Orders must specify the standard package quantity (Std. Pack) or multiples of that quantity.
