With this arrangement of switches and disconnecting switches which are mounted on poles,outside of the building, current may be taken from theMarysville line or from either of the Bay lines.

Itis similar in all respects to No. 5. The last source of energy is at Sacramento. Thisis derived from the sub-station of the Pacific Gas &Electric Company at 6th., & H Sts. There is onemotor-generator set similar to all of the others in useand this is owned by the Northern Electric Company. The total installed capacity of the sub-stations is5,200 kilowatts.
