Starter panel - bottom plate required ?

Starter panel - bottom plate required ?

Starter panel - bottom plate required ?

(OP)
I have a 3.3KV auto transformer starter panel for a centrifugal chiller.  The panel is a floor/pedestal mounted one, but there is no bottom plate.  Cable entry is from top.  

Does this meet the NEMA standards or is it mandatory to have a bottom plate ?

RE: Starter panel - bottom plate required ?

Depends upon which NEMA standard you are needing to comply to. NEMA type 1, then yes, it is permissible for floor standing equipment to have open bottoms against a solid floor or with conduit stub-ups in the floor or a cable trough. it is done all the time in Motor Control Centers. As long as there is no way to get hands or feet into the enclosure.

An open bottom would however violate any other NEMA environmental standard.
