Electrical Installation
The electrical installation for a load bank consists of making connections both for the
Supply-on-Test and for an external supply that is used to power the load bank’s fans and
control system.
The requirements for the two supplies are described separately here, but the following
general points apply in both 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 cables for the supply must be sized appropriately and properly fitted terminals
must be used.
Voltage and frequency ratings
Ensure the external supply rating matches the voltage and frequency of the control circuit.
Exceeding the voltage ratings or supplying the wrong frequency can cause damage to the
load bank so please check the plate carefully before setup.
Figure 2-2
Consult the load bank’s name plate for voltage and current ratings
before making connections
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.

External supply wiring - the fan and controls power source
Refer to the load bank’s rating plate for the external power supply requirements. The
supply must be capable of supplying the fan motor starting current, and must be fused
accordingly. Load banks designed to be movable are fitted with an external power input
plug on the outside of the load bank.

The load bank is supplied with a 16A external cable coupler. Refer to figure 2-4 for correct
wiring configuration.

Connectors
The load bank is fitted with 400A, single pole PowerLock connectors to allow quick
connection and disconnection of the cables.
