Installation Method Examples

Appropriate Reference Methoad For

Determining Current- Carrying Capacity Description

OPEN AND CLIPPED DIRECT:

Sheathed cables clipped direct to or lying on

a non- metallic surface

Method 1

CABLES EMBEDDED DIRECT IN BUILDING MATERIALS:

Sheathed cables embedded directly in

masonry, brickwork, concrete, plaster or the

like (other than thermally insulating

materials)

Method 1

IN CONDUIT:

Single core non- sheathed cables in metallic

or non- metallic conduit on a wall or ceiling

Method 3

Single core non- sheathed cables in

metallic or non- metallic conduit in a

thermally insulating ceiling, the conduit

being in contact with a thermally conductive

surface on one side

Method 4

Multi core cables having non- metallic

sheath, in metallic or non- metallic conduit

on a wall or ceiling

Method 3

The wall is assumed to consist of an outer weatherproof skin, thermal insulation and an inner skin of plasterboard of wood- like material

having a coefficient of heat transfer not less than 10 W/m2K. The conduit is fixed so as to be close to, but not necessarily touching, the

inner skin. Heat from the cables is assumed ti escape through the inner skin only.

Space means a clearance between adjacent surfaces of at least one cable diameter (De). Where the horizontal clearance between adjacent cables exceeds 2 De, no

correction factor need be applied.

Notes: 1) The factors in the table are applicable to groups of cables all of one size. The value of current derived from application of the appropriate factors is the

maximum continuous current to be carried by any of the cables in the group.

2) If, due to known operating conditions, a cable is expected to carry not more than 30% of it’s grouped rating, it may be ignored for the purposed of obtaining the rating factor for the rest of the group.

For example, a group of N loaded cables would normally require a group reduction factor of Cg applied to the tabulated It. However, if M cables in the

group carry loads which are not greater than 0.3Cglt amperes, the other cables can be sized by using the group rating factor corresponding to (N-M) cables.

3) Factors are given for single layer of cables and do not apply when cables are installed in more than one layer touching each other.

4) For circuits having more than one cable in parallel per phase, each set of three conductors should be considered as a circuit for the purpose of this table.

Another important factor for the determination of the conductor size is the maximum

allowable current during a short circuit when the maximum allowable current during a short circuit when the maximum allowable conductor temperature is higher than

during normal operation.

The maximum permissible short circuit current of XLPE cables up to 1Kv with copper conductors can be calculated with the formula:

The values of fault current given in the graph are based on the cable being fully loaded at the start of the short circuit (conductor temperature 900c), and a final conductor

temperature of 2500c, and it should be ensured that the accessories associated with the cable are also capable of operation at these values of fault current.
