Ampacity Management of Cables in
Distribution Networks
When a cable is being
selected for any given
circuit, many factors
have to be considered.
The type of cable may
be dictated by the
installation conditions,
supplier preference, or
company policy as well
as other factors. Similar
considerations dictate
whether single-core or
three-core cables are
selected. When the
conductor size is being
selected, limitations with
respect to voltage drop,
fault current withstand
capability, and ampacity
have to be taken into
account. For distribution
circuits, the design load
that forms the basis for the
ampacity requirements
will usually relate to the
maximum expected future
load for the circuit rather
than the expected initial
load. This presentation
provides details of
many of the factors that
influence the ampacity of
cables used in distribution
circuits.
