Electrically-Operated Ground and Test Device

IB-65060

VI. MAINTENANCE

A. GENERAL

A regular maintenance schedule should be estab-
lished to obtain the best service and reliability from
the ground and test device.  The ground and test
device is designed to require maintenance every
1000 operations or once a year, whichever occurs
first.

Actual inspection and maintenance will depend on
individual application conditions such as number of
operations, time between uses, and storage condi-
tions. When the ground and test device has been in
storage for an extended period of time, it must be
inspected and cleaned before being used.  See
Section IV. INSTALLATION, C. STORAGE, D.
PREPARING THE ELECTRICAL GROUND AND
TEST DEVICE FOR USE.

A permanent record of maintenance work and inspec-
tions should be kept.  The degree of record detail
depends on the operating conditions.  The record
should include the dates and results starting from the
date the device is first put into service.  Dates and
results of inspections and routine maintenance
activities should be recorded.

B. INSPECTION AND CLEANING

Inspect the ground and test device for loose or
damaged hardware or parts.  Tighten any loose
hardware, and replace missing or damaged hardware
or parts.

When necessary, remove loose dust and dirt from the
ground and test device with a vacuum cleaner, a
clean, dry cloth, or an industrial-type wiper.  DO NOT
use an air hose to clean the ground and test device.
Dirt or grit may be blown into critical parts, including
bearings, which will cause excessive wear of the
parts.

Primary insulation should be cleaned if needed.
Wipe insulation parts clean with a dry lint-free cloth
or an industrial-type wiper.  If dirt adheres and will not
come off by wiping, remove it with distilled water or a
mild solvent such as denatured alcohol.  Ensure that
the ground and test device is dry before use.  DO
NOT use any type of detergent to wash the surface of
the insulators, as the detergent may leave an electri-
cal conducting residue on the surface as it dries.

C. LUBRICATION

The contact surfaces of the primary disconnect stabs
and the fingers of the ground shoe should be lubri-
cated with a thin film of Mobilgrease 28.  Before use,
particularly if the ground and test device has been in
storage for a long period of time, wipe these surfaces
with a clean, dry cloth, and apply fresh lubricant.

VII.  RENEWAL PARTS

A. ORDERING

Should any part require replacement due to wear or
damage, order renewal parts from Powell Apparatus
Service Division (PASD).

When ordering parts, provide the following informa-
tion from the ground and test device name plate:

•

Name of the ultimate user

•

Location of the installation

•

Type of device including rated voltage and
rated amps

•

Serial number of the device (see device name
plate)

•

Description of the part

•

Photo of the device with the needed part
marked will be helpful in assuring that the
proper part is furnished

To order parts, visit the Powell Web site at
www.powellservice.com or call 1-800-480-7273.
