to the rules of the RCC-M. As used in thissubsection, the term "support" shall encompass

structural elements which are intended to carry

these loads to the fabric or to a structural steelmember of the building structure, in the extentthat these structural elements were designed to

fulfil this function. The rules of this subsection

do not apply toa! structural steel members referred to abo#e,

as defined in $ %&&', such as motors, #al#e

appro#ed shall be mounted in a configurationwhich is representati#e of ser#ice

configurations. The following conditions shall

be met- the procedure for securing attachments shall

be properly followed,- the test load shall be applied in the same
