The discussion focuses on alternatives for supporting electrical cables in high-rise buildings exceeding 40 floors. The designer initially recommends using OZ / GEDNEY type S cable clamps with pozi-grip, which are noted to be costly. Participants suggest considering Hubbell-Kelems support grips as a more economical option, especially if the installation allows for interruptions in the PVC conduit every 60 feet, as per NEC Table 300.19(A). Additionally, the use of covered cable trays is recommended for effective cable management.

Welcome to the PF.eduardotobon said:I have a project of more than 40 floors in height, in which the cables go from ground floor to each of the floors (1 tube 2-1/2" PVC + 4 conductors THHN 3/0 + ground in the higher floors ) The designer recommends the use of OZ / GEDNEY type S cable clamps with pozi-grip These supports are very expensive and I want to know what alternatives are there to support the cables since the path is long.
