    Not really looking for other info, but details are what make an installation Code compliant.

    For example. do you know whether the Main Switchboard will be overloaded by adding loads to it? The...

    In addition to assuming a storage-type, I figured such being 3Ø and drawing 100A would likely be large enough... but an assumption all the same. :D

    The requirement doesn't say specifically how to measure.

    That said, I imagine the intent is shortest route of a 6' cord. Have you considered whether it is shorter by running a cord under the door?

    Barring omitted pertinent details, yes... but will require secondary protection. See 450.3(B) and Table

    Just covering possibilities. Early on you mentioned cable reel as a possibility. If secured to the moving room, no issue. If reel is at the stationary end, then you'd have a termination in between.

    Not real familiar with 620, but seems rather unsafe if a shunt trip was required. What if a person was actually in the dumbwaiter when it was tripped. With manual reset required, hard to tell how...

    Assuming a storage-type water heater, 422.12 requires it to be considered a continuous load. 210.19/20 requires 125% for conductor and OCPD ratings.

    Look at 225.18.

    Line-to-line voltage is used for the nominal voltage determination.

    225.60 is in Part III, which is for over 600V installations.

    230.24 is for not over 600V... but Part VIII doesn't supplement or modify 230.24 but the Informational Note of 230.200 refers one to...

    Second thought... if there is any cable termination between small building and moving room, I don't see how it could qualify under uses permitted [400.7].

    I don't believe so. Direct buried is where the earth is in contact with the cable. Besides, is direct burial is prohibited?

    I don't see why there would even be a need to install flexible cable in the underground raceway portion. The flexible cable should only be from the cable reel to the moving room.

    If they do go...

    Hard to say. Definitely not ideal at the instances you took the measurements. As you noted, the current changes with loads getting turned on and off. Just using a one-reading meter, the powered...

    Of course there are "unlesses". But it doesn't change the minimum ampacity possible... just under that condition. Same if a load exceeds 16A... it's a condition which would raise the lowest...

    The secondary conductors would be considered protected if they are of an ampacity greater than the primary OCPD rating multiplied by the primary-to-secondary voltage ratio. Say primary is protected...

    The grounded conductor (neutral) is permitted to be smaller than the ungrounded conductors. Code isn't specific whether 'smaller' is regarding ampacity rating or physical size. The last sentence of...

    I think Gus took the right approach, being 1" EMT is limited to 20 THHN conductors.
