    I don't think any "enamel" coated conduit has been on the market in the last 40 or 50 years.
    Here is the information from the UL White Book for "Rigid Ferrous Metal Conduit (DYIX)"

    Probably because the editors never changed the commentary when the 2005 wording of "125 volt, 15 and 20 ampere circuits" was changed in the 2008 code to say "outlets not exceeding 240 volts".

    Why would you try to make the other side's points for them?...when I debated in college you would never say anything favorable to the other side...you lost points if you did.

    I am not sure there was even an arc...looks more like heat damage to me. I would guess a poor connection issue, either at the fuse clip or at the actual switch contact.

    That is based on the design the elements...stoves and ovens use those types of elements and they don't need to be in water.

    I think they are called "calrod" or something like that.

    A typical building, even though is has those "harmonic" producing loads, doesn't normally have enough of those loads to require counting the neutral as a current carrying conductor.
