Only thing NEC requires is:

225.52

(E) Uniform Position. Where disconnecting means handles
are operated vertically, the ?up? position of the handle shall be
the ?on? position.
Exception: A switching device having more than one ?on?
position, such as a double throw switch, shall not be required
to comply with this requirement.

a readily accessible place. They shall be installed such that
the center of the grip of the operating handle of the switch

than 2.0 m (6 ft 7 in.) above the floor or working platform.
Exception No. 1: On busway installations, fused switches
and circuit breakers shall be permitted to be located at the
same level as the busway. Suitable means shall be provided

@jrae,
you said the question asked for the direction? Not sure 404.8 applies in this case!

edit to add: I can see someone linked this thread with another. This is why they posted section 404.8

I would not put too much faith in an interview question. Most of the time those questions are based on how they want it done.
