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/m2
K. 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.

Description
ON TRAYS:
Sheathed cables on a perforated cable tray,
bunched and unenclosed. A pertorated cable
tray is considerd as a tray in which the holes
occupy at least 30% of the surface area
Method 11
IN FREE AIR, ON CLEATS, BRACKETS OR A LADDER:
Sheathed single- core cables in free air (any
supporting metalwork under the cables
occupying less than 10% of the plan area
Two of three cables vertically one above the
other, minimum distance between cable
surfaces equal to the overall cable diameter
(De); distance from the wall not less than
0.5De
Two or three cables horizontally, with
spacings as above
Three cables in trefoil, distance between
wall and surface of nearest cable 0.5De or
nearest cables 0.75De
Method 12
Sheathed multicore cables on ladder or
brackets, separation greater than 2De
Sheathed multicore cables in free air
distance between wall and cable surface not
less than 0.3De

 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.

The correction factors tabulated above relate to the disposition of cables illustrated in terms 18 to 20 of Technical Table 1.3 and are applicable to the
current- carrying capacities for Reference Methods 12 or 13 of Technical Table 1.2.
When cables having different conductor operating temperatures are grouped together the current rating shall be based on the lowest operating temperature
of any cable in the group.

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 900
c), and a final conductor
temperature of 2500
c, and it should be ensured that the accessories associated with the cable are also capable of operation at these values of fault current.
