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.

Guy,
I forgot to send the attachment with a previous e-mail.
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.
Chris

Hi Chris I have a couple of Questions about the Capacitor Bank . 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 ?
Thank you
