When the circuit breaker is received, check
for signs of damage. If damage is found or
suspected, file claims as soon as possible with
the transportation company and notify the
nearest Powell representative.
Estimated size and weight for shipping a
PowlVac DHP replacement circuit breaker on a
pallet:
• Size: 31” width x 35” depth x 61” height
• Weight: 850 lbs.
The circuit breaker is attached to the pallet by
three metal shipping brackets. When these are
removed the circuit breaker may be removed
from the shipping pallet. Refer to

After the circuit breaker has been removed
from its shipping pallet it may be rolled on
its own wheels on a level surface. This is the
preferred way of handling the circuit breaker.
When rolling the circuit breaker, it should be
pushed and steered by the steel frame or the
front cover.
!
CAUTION
Do NOT handle or move the circuit breaker
by the primary disconnecting devices, as
damage may occur.
If necessary, the circuit breaker can be moved
by an overhead crane. To lift the circuit breaker
with an overhead crane, use the two lifting
points which have been provided for hooks at
the top of the circuit breaker (Figure 4, a).

Shipping and storage of electrical equipment
requires measures to prevent the deterioration
of the apparatus over a long unused period.
The mechanical and dielectric integrity must
be protected. Electrical equipment is designed
for use in a variety of environments. When
the equipment is in transit and storage, these
design considerations are not fully functional.
In general, the following measures must be
considered.
1. Equipment designed for indoor installation
must be stored indoors in a climate
controlled environment to prevent
condensation of moisture. Exposure to rain
and the elements, even for a short period,
can permanently damage the equipment.
Space heaters within the equipment should
be energized, if so equipped. Humidity
controlling desiccant materials should
be utilized when space heaters are not
provided or cannot be energized. The
temperature should be kept above 33°F/1°C
and below 140°F/60°C. The relative
humidity should be kept below 60% or a
dew point of 15°C/59°F. The equipment
should be stored in such a manner as
to leave all doors and panels accessible
for inspection. The equipment must be
inspected on a routine basis to assure
operational integrity.
