Follow these tips to prevent coating damage during installation
Although engineers and electrical designers recognize the
performance advantages of using PVC-coated conduit in corrosive
environments, making sure field installers understand and adhere
to accepted installation practices continues to be a challenge.
But it doesn't have to be this way. All it takes to realize a
successful installation is to follow a few simple precautions,
use the right tools, adhere to manufacturer-specific
recommendations, and protect the coating at every stage of the
installation. In fact, PVC-coated conduit installation
procedures are pretty much the same as those used to install
standard galvanized conduit, with a few minor exceptions.
Materials and tools. There are three basic types of PVC-coated
conduit: primary PVC coating over bare steel, PVC coating over
listed galvanized steel conduit, and primary PVC coating over a
supplementary coating of zinc. These PVC-coated raceways are
generally installed as a system, which mean
