9.6 Paint refinishing
Indoor switchgear is finished with ANSI-61 gray
acrylic enamel paint (PPG W42713, part number
21525032650). To refinish damaged areas, remove
all loose paint, rust, scale, oil or grease. Sand any
scratches smooth using 220 grit paper or finer.
Apply a coat of good acrylic enamel primer
(Sherman-Williams E61 A 60, part number
21525025200) with a viscosity of approximately
24-32 seconds using a #2 Zahn cup. Reduce with
D5B9 Xylol (part number 21525038000) if needed.
Air dry the primer for a minimum of 30 minutes,
then apply the finish color coat of acrylic enamel.
The top coat should be applied within 24 hours for
best adhesion. If the area is to be spray-coated,
thin the acrylic enamel with D5B9 Xylol (part
number 21525038000). This thinning should only
be necessary if the paint was received in a five
gallon drum or more.
The recommended viscosity for the W42713
topcoat should be 24-32 seconds with a #2 Zahn
cup. The curing schedule for PPG W42713 is dust
free in 5 minutes, touch in 30 minutes, handle in
60 minutes, full cure in 7 days. Both the primer
(Sherwin-Williams E61 A 60) and paint (PPG
W42713) should be applied only when temperature
is above 55 degrees Fahrenheit. Application of
special paint will be per the manufacturer’s Product
Data Sheet which includes instructions on thinning
and application.
9.7 Circuit breaker lifting mechanism
Under normal conditions, no special
maintenance procedures or lubrication is required
for this device. If the cable is abraided under any
condition, it should be inspected for broken
strands or other damage and replaced if necessary.
