Electrical Installation
The electrical installation for a 8800 S
ERIES
load bank consists of making connections for
the Supply-on-Test, an external supply used to power the load bank’s fans and control
system and, finally, a single phase supply that provides power for the control room lights
and cabinet heaters.
Figure 2-1
An 8800 S
ERIES
load bank can have up to three separate power sources.
The requirements for these three supplies are described separately here, but the following
general points apply in all cases:
•
The work must be carried out by a person with the appropriate training, qualifications
and experience.
•
All cables should be appropriately rated and installed in accordance with current
standards and accepted practice.
•
The connections to the load bank may be intended to be temporary, but it is essential
to apply the same standards to the cable glands and terminations as if the installation
were permanent.
Note: The Load Bank
supply cables must be
protected by a Short
Circuit Protective
Device (SCPD), which
is suitably rated to the
capacity of the supply
cables.
