[2] [3] For shallow water surface supply air diving, the diver's umbilical is typically a 3-part umbilical comprising a 3 ⁄ 8 inch (9.5 mm) bore breathing gas hose, 1 ⁄ 4 inch (6.4 mm) bore pneumofathometer ("pneumo") hose, and diver communications cable, which usually also serves as a lifeline strength member. The pneumo hose is open at ...

A home with aluminum wiring installed prior to the mid-1970s (as the stock of pre-1972 aluminum wire was permitted to be used up) likely has wire made with the older AA-1350 alloy that was developed for power transmission.
For instance in North America, Grosbeak is a 322.3 mm 2 (636 kcmil) ACSR conductor with 26/7 Aluminium/Steel stranding whereas Egret is the same total aluminium size (322.3 mm 2, 636 kcmil conductor) but with 30/19 Aluminium/Steel stranding. Although the number of aluminium strands is different between Grosbeak and Egret, differing sizes of the ...
