Bill, I think this is just another example of a munufaturer that has no idea how electricl systems work. Grounding is not required here, but bonding is. As Tom stated a rod will not help any if there is a fault in the heat cable. Does the wording in 426-3 about installing cord connected snow melting equipment per Article 422 mean that we don't have to provide GFP for the snow melting equipment as required by 426-28?
