MATERIALS
Do not use a combination of materials that forms an electrolytic couple of
such nature that corrosion is accelerated in presence of moisture unless
moisture is permanently excluded from the junction of such metals. Where
unusual conditions exist which would cause corrosion of conductors, provide
conductors with protective coatings or oversize conductors. Where
mechanical hazard is involved, increase conductor size to compensate for
hazard or protect conductors by covering them with molding or tubing made
of wood or nonmagnetic material. When metallic conduit or tubing is
provided, electrically bond conductor to conduit or tubing at the upper and
lower ends by clamp type connectors or welds (including exothermic).
