Furthermore this cable shall be sized no smaller than #12, unless on a switched leg, or by special permission of the electrical inspector.
      (1)   Unless special permission is granted, anything other than the installations mentioned above (commercial installations for the purpose of this ordinance) shall be installed in approved metallic raceway, no smaller than metric designator 16 (trade size ½").
      (2)   Metallic sheathed cable of metric designator 12 (trade size 3/8") may be used in no lengths greater than 6', and where not exposed to physical damage, to facilitate the wiring of branch circuit receptacles, and lighting whip. Longer lengths may be permitted with special permission of the electrical inspector.

         (b)   This conduit shall have a weatherproof junction box sized in accordance with the latest edition of the NEC ® for terminating the conductors from the service disconnect to the mobile home.
      (2)   The mobile home park owner, rather than a tenant, shall furnish and install the mobile home service equipment.
