Enclosure Finish
The responsibility for ensuring that the nish protects the
enclosure lies with both the man ufacturer and the user.
Enclosures provided are nished with S&C’s Ultradur II
Outdoor Finish, which provides lasting protection. To retain
this protection, the user should take periodic corrective
action as follows:
STEP 1� Touch-up any penetration of the nish to bare
metal—such as scratches and abrasions caused
by shipping or vandalism—to maintain the
original integrity. S&C touch-up nish and primer
are available in aerosol spray cans. See Figure 54.
No other nish or primer is approved. The area
to be touched up should be cleaned to remove
all oil and grease. Sand the area, removing any
traces of rust that may be present, and make sure
all edges are feathered before applying primer.
STEP 2� Provide an occasional simple wash -down—such
as an automobile would be given—to remove
surface contaminants. Use any ordinary mild
household detergent solu tion.
STEP 3� In those cases where the enclosure must be
renished by the user before the nish has weath -
ered—for example, to match other equipment—a
special precaution must be taken. The entire
surface must be sanded to provide a tooth to bond
the new coat to the Ultradur II Outdoor Finish.
Maintenance Recommendations in Extremely
Corrosive Environments
For applications involving exposure to extremely corro-
sive environmental conditions (i.e. industrial chemicals,
CaCl
2
, etc.) that may affect the condition of the switchgear
tank, S&C’s recommended periodic cleaning could provide
extended life. Contact S&C if corrosion on the tank is found.
For outer pad-mount or custom-designed enclosures
that have already experienced some corrosion, follow the
instructions in the “Enclosure Finish” section for specic
instructions. If not further exposure to a corrosive environ-
ment is expected, one treatment may be enough.
To remove accumulated contaminants, use a mild deter-
gent and potable water. The detergent should be mild soap,
not bleach or any cleaners that contain chloride. Cleaning
alone may be sufficient in most cases, but the application of
a water-displacing oil-based spray after washing is further
recommended for extremely corrosive environments.
