| I've got a code question and can't seem to find the answer, so I'm
asking the experts here for help.
This is a commercial building containing office areas, break rooms
etc. This building also has a communication and dispatching area with
monitors for a CCTV and data input from remote sensors. This building
is in the USA and is to be wired to the 2002 NEC. The building is in a
very rural area of Texas where competent commercail/industrial/High
Tech electrical inspectors are very rare to say the least.
The communication and CCTV/senser room originally had one emergency
back up generator. This generator went through typical switchgear to a
dedicated emergency power distribution system.
At a later date this room was expanded, more equipment added and a
second emergency generator added. This involved building another
distribution system for the additional equipment because of
insufficient capacity of the single generator. Switchgear kept the two
systems separated under emergency generator operation.
The company now want's to further expand this communication and
monitoring center. An additional generator is available for free and
the current plan is to use that third generator to provide emergency
back up power for the additional equipment just like generator #2.
This is being chosen because of cost savings of using the third free
generator rather than up sizing gen. #2 or #1
I am somewhat involved in this project and believe we have a major
code violation. I have been pouring through the 2002 NEC however and
can't find a specific article that seems to forbid it. Help ! Do you
see a code violation and if so what article ?
