These Notes and Legend refer to tables D-1, D-2 and D-3 on the following
Load on building system will be based on the feeder amps not the
If the requested additional load to the building, when added to the
existing building loads, creates a marginal condition on the service
size, then, the building loads will be looked at on an individual basis to
verify actual demand load based on the actual NMCI seat count. If this
demand load exceeds building capacity, then DoN must provide
additional power to the building.
If existing air conditioning within the facility is adequate to support the
NMCI requirements, the air conditioning ampacity (site cooling amps)
should be subtracted from the total feeder ampacity indicated. This
would also reduce the breaker and wire sizes.
Cooling (Heat to Room) only includes all NMCI equipment. Other
loads such as lighting and building envelope must be added.
These tables were developed for the NMCI contractor survey and
design teams. The nomenclature is therefore, not self explanatory. If
detailed information is required, it is available from the NMCI
Where an Equipment Cooling Module (ECM) is indicated, it refers to an
inside cabinet air conditioner with independent ducting out of the room
