Preparation for installation
Prior to installation of the type SDV6
distribution circuit breaker, careful design,
planning and construction of the
foundation or base on which the circuit
breaker will rest must be made. A
thorough analysis and careful construction
may alleviate many problems at the time
of installation, and during operation. It is
important that a relatively level surface be
provided capable of supporting the weight
of the type SDV6 distribution circuit
breaker, and 0.75 inch diameter anchor
bolts are not recommended.
Figure 4: Anchoring type SDV6 distribution
circuit breaker on page 14 illustrates
typical locations for anchor bolts. No
special leveling procedures are required.
Prior to installation of a type SDV6
distribution circuit breaker, study this
instruction book and the circuit breaker
drawings, such as outline, current
transformer diagram, elementary diagram,
connection diagram, protective relay
diagram and electrical bill of material and
nameplate engraving. Special attention
should be given to the foundation
information contained in this instruction
manual as well as the information
provided on the equipment drawings.
Verify the foundation conforms to the
requirements described in this instruction
manual and the outline drawing.
The type SDV6 distribution circuit breaker
is shipped with the legs attached. The legs
must be set to the desired height.
Directions are given in the notice decal.
Location
The circuit breaker should be located so
that it is readily accessible for manual
operation and inspection. Ample clearance
should be provided for doors and panels to
swing open, or to be removed for servicing
the circuit breaker.
