Re: `Clark Building', 7357 SW Beveland
As is required for this installation, I am submitting the attached documents for review
and approval or correction. I have included 2 of each of the following: building floor
plans, fault current calculation by PGE, load calculation, and a service and a
modular metering layout. Upon completion of the review please return one copy to
my office.
This project is a new multi- tenant, multi -use building. The construction type is V -N.
As such, the wiring method will be a combination of type NM -B cable and conduit.
The available fault current for this project is 26,469 amps per Ken Gutierrez of PGE.
All main breakers will be rated 42KAIC.
The permit application is being submitted at this time. I have included both the plan
review fee and the permit fee with this information.
Please call if you have any questions. Thank You.
Sincerely,
Stuart M. Jarme
