Size
The correct pit/surface ducting channel
size must be selected - each of the
following aspects of cable management
need to be reviewed to choose the right
width, length and depth of enclosure. |
Important factors include:
Minimum depth coverage for cables
Purpose of pit
Is segregation of cables required?
Will the pit be used for storage?
Other criteria |

Location
a. Traffic & Loading
Traffic – where enclosures are located
in vehicular or non vehicular areas and
where the possibility of non-deliberate
traffic in non-vehicular areas exists.
Loading – load standards are a tool
to enable an objective comparison
of products by providing an
independent measurement scale.
b. Durability
To ensure a long life, enclosures,
according to their intended location,
must be selected on the basis of their
materials and installed correctly. |
Important to note:
Pits positioned along a cable route can typically cause various types of load scenarios.
Each pit location should be individually considered

Safety & Security
Cable enclosures must not only facilitate
overpassing foot or vehicular traffic,
but also protect humans and livestock
against physical contact with potentially
live parts through accidental contact,
unauthorised access and injury from
on-site manual handling.
Additionally, the contents of an
enclosure must be adequately protected
from the ingress of water and foreign
matter. |
Important factors include:
Level of security required
Minimising the chance of damaged cables making lids live
Earthing of pits
Slip resistance
Ingress of foreign matter
Manual handling
Water ingress |

Site & User Requirements
a. Installation & Maintenance
The correct method of installation is critical
for an enclosure’s long term performance
and structural integrity. Consideration must
be given to ease of authorised access to
the enclosure.
b. Aesthetics & Identification
Should the cover be discreet and
match the pavement surface?
Do contents need to be
distinguished from other services?
Are there other unique
requirements? | Important factors include:
Encasement
Conduit entry
Accessories
Access
Visual continuity
Pit marking |
