5 - Electrical Installation
For safety purposes, only competent personnel should perform the electrical installation. All
equipment should be installed to current Electrical Regulations and Standards.
In order to obtain the maximum light output from the searchlight, it is essential that the full
operating voltage of the lamp fitted be applied to the lampholder contacts.
Method of Electrical Connection
1)
Disconnect the supply before working on the electrical system;
2)
The searchlight must be connected to a fused electrical supply, using suitably sized cable;
3)
If the searchlight is located a considerable distance from the supply, provision must be made in
the cable size in order to overcome the voltage drop. The following table should be used for
indication purposes only:

4)
Whenever possible cable terminations should be made below deck and with approved terminal
devices;
5)
If a spare auxiliary fuse or circuit breaker is not available, one of the correct type and rating
should be fitted and connected to a positive supply. It is advisable to locate a bus bar or main
connection and avoid any direct connection to the supply:
