About once a month I get a call to replace the old 2” rigid metal conduit that stubs up from the ground into the bottom of the meter can. The iron oxidation that occurs on the rigid metal conduit is always more noticeable or prominent right at grade . The conduit always breaks right at the soil line . Just below grade the conduit is rusted but not broken, it’s still in tact. Just above grade the rigid metal conduit is intact.
I’m an electrical contractor in the coastal area here in Florida and I see the strange phenomenon all the time.
Because of this , I have been obsessing this week going down the rabbit hole over Metal alloys, Iron oxidation, galvanizing on conduit & enclosures, powder coating, liquid enamel coating blah blah etc.
Why is the iron oxidation so pronounced right at grade?
Is there a product data information that tells you what metal alloys are used for rigid metal conduit?
Is RMC galvanized with tin or Zinc?
And what about GE , SQ-D , or Eaton outdoor enclosures? I can’t find a product data sheet to tell me what the metal alloys are used for those specific enclosures. Are they galvanized, are they powder coated or are they liquid coated?
