300.5 (D)(3) Requires a warning ribbon at least a foot above unencased service conductors that are buried more than 18" deep. Don't you think that this should be required on other underground installations as well?
OK, maybe the example is a little silly, but I think my question is a valid one.
Why should it be a requirement to put a warning ribbon above a 100 Amp residential 120/240 Volt service lateral, maybe fed by a 25 KVA transformer, when there's no requirement to provide the same type of warning above a 1000 Amp 480 Volt feeder?
Is my reasoning even goofier than usual? What am I missing here?
