Why might conduits be painted or coated?

Conduits are commonly painted or coated primarily to provide insulation and corrosion resistance. The coating acts as a protective barrier that helps prevent electrical conductivity, which is critical in ensuring safety when conduits are installed in environments where they may be exposed to moisture or corrosive substances. This protective layer helps to prolong the lifespan of the conduit by preventing rust and degradation, which could lead to failure in electrical systems.

Additionally, insulation improves safety by preventing unintended electrical contact with the conduit, which could pose shock hazards. The choice of coatings can vary depending on the environment and specific requirements of the installation, ensuring that the conduits remain effective and safe over time.
