Re: FuelCell Power Plant - Area Classificaiton Issue

This looks like it belongs in the specs. What do you think?

Sorry in the earlier transmittal I was interrupted and sent the message by
mistake. The red text below is what I added to insure that the minimum
design standards are satisfied. From the discussion this morning, the
sensing instruments should or must be rated class I, div 2 and Fuelcell was
not willing to state that minimum was included in their design basis. The
wording below should bring closure to this issue, when placed in the contract.

Mike:

This is the recommended verbiage to address area classification issues:

The electrical system design and installation shall be in compliance with the
requirement of NFPA 70 (NEC), in particular, Article 500 with respect to
Hazardous Locations. The classification of locations shall be as recommended
by API RP 500 (Recommended Practice for Classification of Locations for
Electrical Installations at Petroleum Facilities.) The design compliance
with the NFPA requirements shall be demonstated in a design review or HAZOP
review meeting which includes representatives of Enron North America in the
review process.

Regards,

Dom
