Transformer disconnect requirement

[bgelectric]

Can someone give me a code reference for the requirement for disconnects for transformers.
Are disconnects for transformers required to be within the location of the transformer?
Plans show a meter with a disconnect beside it, then another disconnect prior to the transformer..

See 450.14 in 2011.

450.14 Disconnecting Means. Transformers, other than Class 2 or Class 3 transformers, shall have a disconnecting means located either in sight of the transformer or in a remote location. Where located in a remote location, the disconnecting means shall be lockable, and the location shall be field marked on the transformer.
