Recommended Inspection Maintenance
Recommended Inspection Maintenance
Southern States’ disconnect switches are designed to operate with minimum maintenance. While disconnecting
switches are not readily serviced at frequent intervals,
periodic inspection is important for satisfactory operation
and maximized overall life . Frequency of inspection and maintenance depends on the installation site, weather,
atmospheric conditions, experience of operating personnel, and any special operation requirements.
During operational testing, the switch should be opened and closed several times, if possible, to clean the contacts
and free the moving parts. A visual inspection, when the switch is wet, or temperature scanning detector may
indicate hot spots that could serve as potential sources of trouble. Directional microphones or ultrasonic detectors
can be used to locate local corona sources on the switches which can be eliminated during normal switch
maintenance.

* NOTE: Inspection/maintenance is suggested to be performed every two (2) years when installed in harsh environments with
excessive airborne contaminants such as salt spray and industrial pollutants.
It is recommended that maintenance on these switches be performed in accordance with ANSI
STANDARDS
C37.30.1-2011
. In addition, well-established live-line servicing and maintenance
procedures may be used in accordance with user practices and local and OSHA regulations.
