System Cables
Before installing the system cables, you need to take the following points into
consideration.
1.
All cables need to be well secured and protected from physical damage and
exposure to heat and humidity.
2.
Cables with an acute bend should be avoided.
3.
Where a cable passes through an exposed bulkhead or deck head, a watertight
gland or swan neck tube should be used.
