Building Tomorrow® December 5, 2013 City of Springfield Electrical Permit Department 225 Fifth Street Springfield, OR 97477 Attention Guy Dixon: Rosboro would like to request an Electrical Plan Review for the installation of a 500 KVAR automatic power factor correction capacitor bank in our Mill A Sawmill. This work would be performed under our Master Permit Number 811-SPR2013-00939. This capacitor will be installed next to an existing 3000A switchboard and be fed with a 1200A breaker. The breaker will be set for 900 amp long time trip. Conductors will be sized to allow for the addition of up to 250 more KVAR in the future if needed. Our plant is located at 2509 Main Street here in Springfield. Please contact me with any questions or concerns. I'm usually available from 6 am to3:30 pm. Sincerely, Chris Miller Systems Tech.

NEC 460.2 (A): Each cell contains less than 3 gallons of combustible liquid. I've attached a spec. sheet for the capacitors in this installation. They are part# PSP0025H33S. The dimensions are 3.75" x 4.56" x 10.5" which equals 179.55 cu. inches. 1 gallon = 231 cu. inches so . each cell could only contain a little over% of a gallon max. I have requested information from the manufacturer concerning the quantity and type and will forward it to you when I receive it. NEC 460.2 (B): The entire unit is installed in a NEMA 12 enclosure. Let me know if you need anything else. Thanks.

Nec 460.2 A and B talk about flammable Liquid and Accidental Contact . Would you please reference these two Paragraphs and make comments regarding whether or not these codes are being met in your design ?
