In rail transit industries, stray current related corrosion is predominant. NEC is silent (or suttle about it) in a way that Authority in Jurisdiction can decide the need for protection against corrosion of RGS (Rigid Steel Conduits) or other underground metallic infrastructure near 3rd rail (the one carrying DC 650 volts power for train traction).
I know underground storage tanks are usually coated with corrosion resistant tapes/paint, or encased in concrete.
Many Transit systems 9NYCT, etc.) require all underground conduits in concrete encasement as a sound engineering practice.
Do you know of any standards/code, etc that may insist on such requirements? If not, why not? Why NFPA 130 addresses such requirements.
I would appreciate input from forum
Thanks.
