[QUOTE="Ardet R, post: 466873, member: 30040"] If the heater is labelled as Class II and the cable is entering the enclosure through a protected entry and no exposed insulation is accessible within the cabinet then the cabinet ought to be a random piece of metal and not part of the electrical installation, in this case the likelihood of the cabinet being an extraneous conductive part is very (very) low and bonding should not be required, and would be prohibitively inconvenient to do (though the latter does not remove the requirement, if it exists). If the heater is class I and mounted to the cabinet and / or there is exposed insulation and so the cabinet is being used as an enclosure for electrical parts that may cause the cabinet to become live, then the cabinet would be part of the electrical installation and so would require earthing. From what you describe I would expect that the cabinet would not require either earthing or bonding, but this would be down to your assessment on site as you know the details of the installation.
