SECTION 3 .0-Stora g e , Safety,
I t i s recom mended that the breaker be put into service
i m mediately in its permanent location. If this is not possi
ble, the fol lowing precautions m ust be taken to insure the
proper storage of the breaker:
1 . The breaker should be carefully protected against
condensation, preferably by storing it in a warm dry room,
since water absorption has an adverse effect on the insula
tion parts. Circuit breakers for outdoor switchgear should
be stored in the equipment only when power is available
and the compartment heaters are in operation to prevent
condensation.
2. The breaker should be stored in a clean location free
from corrosive gases or fumes. Particular care should be
taken to protect the equip ment from moisture and cement
dust, as this co mbination has a very corrosive effect on
many parts.
CAUTION:
IF THE BREAKER IS S TORED FOR
ANY LEN G TH OF TIME, IT SHOULD BE INSPECTED
PERIOD/CA L L Y TO SEE THA T RUSTING HAS NO T
S TA R TED AND TO A SSURE G OOD MECHANICAL
CONDITION. SHOULD THE BREA KER BE STORED
UNDER UNFA VORABLE A TMOSPHERIC CONDI
TIONS, IT SHOULD BE CLEANED A ND DRIED O U T
BEFORE BEING PLACED I N SERVICE.

3 . 1 Safety
Each user m ust maintain a safety program for the protec

potential hazards associated with electrical equipment.
The following requirements are intended to augment the
user's safety program , but NOT supplant the user's
responsibility for devising a c:::> m pl et e safety program .
The following basic industry practiced safety require

person's knowledge; his m ental awareness; and has planned
and executed actions often determ ine if an accident will
occur. The m ost im portant m ethod of avoiding accidents is
for all associated personnel to carefully apply a thorough
understanding of the specific equipment from the viewpoints
of it's purpose, it's construction, it's operation and the
situations which could be hazardous.
All personnel associated with installation, operation and
maintenance of electrical equipment, such as power circuit
breakers and other power handling equipment, must be
thoroughly instructed, with periodic retraining, regarding
power equipment in general as well as the particular m odel
of equipment with which they are working.

nance practices such as OSHA publications, National Electric
Safety Code (ANSI C2
, The National Electrical Code, and
NFPA 7 OB Electrical Equipment Maintenance m ust be
c losely studied and followed. During actual work, supervi
sion should audit practices to assure conformance.
3. Excellent maintenance is essential for rel iability and safety
of any electrical equipment. Industry publications of recom
menced maintenance practices such as ANSI/NFPA 70B,
Electrical Equipment Maintenance, should be carefully stud
ied and applied in each user's formation of p lanned
maintenance.
