Equipment Cabinet Factory Wiring
Internal equipment cabinet wiring shall be factory installed, color coded
and bundled neatly or routed via wiring duct. Installation of cables and
wiring shall be as specified.
2.6.23.1
Termination
Terminations shall be made with pressure type connectors or lugs. Stranded
conductors shall not be wrapped around screw type terminals. Incoming
cables shall be connected to CMS controller via terminal blocks. Internal
wiring shall be terminated at one side of the terminal blocks.
2.6.23.2
Nameplate for Device Inside Equipment Cabinets.
Nameplate for device mounted inside equipment cabinet shall be stamped with
the device number only. Nameplate shall be 10 mm 3/8 inches wide stainless
steel tape, attached to the device with stainless steel wire.

Continuous Emissions Monitoring
**************************************************************************
NOTE: A continuous emissions monitoring system
(CEMS) is required by the Clean Air Act Amendment
(CAAA) of 1990 if the fuel utilized is oil or coal
and the heat input is 3 megawatt (10 million BTU/HR)
or greater. A CEMS may also be required by state or
local laws. If a CEMS is necessary the designer
shall review the CAAA and the relevant state or
local law early in the project to allow time to
incorporate the required CEMS specification and to
determine which flue gas emissions will be included
in the required reports. Before acceptance of the
installation, the Contracting Officer shall be
furnished a written test report which provides
documentation that the CEMS equipment has passed
factory and field certification tests required by
federal, state and local regulations. The
investigation will determine if the reported values
may be calculated or should be direct measurements.
The CAAA includes measurement options for gas/oil
fired units depending upon the particular category
of unit as defined by the regulations. Fill in the
data to state what method of measurement or
calculation will be utilized for the determination
of the report variable.
Emerging flue gas flow monitor technologies are
available. The traditional differential pressure
technique specified uses familiar equipment that can
be maintained by plant personnel. This type of
measurement device has reliably satisfied regulatory
requirements. The possible use of other
technologies should include a thorough investigation
of flue gas flow monitor regulatory requirements and
