Is it ok to install a non-coated box along with my PVC coated conduit installation?

Question: Chris, is it ok to install a non-coated box along with my PVC coated conduit installation?

Answer: Non-coated boxes should never be used, only coated boxes will provide the protection necessary to prevent corrosion and maintain the necessary ratings. Also, non-coated products of any type should never be used with coated products. The product should be installed as a system and non-coated products compromise the integrity of the installation.

Wrong conduit box type                               Coated conduit box is correct
