Table - B Current ratings

The current rating given in tables are based on normal conditions of installation described below:

  1. Maximum Conductor temperature 70O C for PVC insulation & 80O C for HRPVC insulation.
  2. Thermal Resistivity of soil 150O C cm/w
  3. Thermal Resistivity of PVC 650O C cm/w
  4. Ground temperature 40O C
    (To the highest point of cable laid direct in the ground)
  5. Depth of laying 75cms

Note: For cables in air , no reduction in current rating is necessary provided that

  1. The horizontal clearance between circuits is (a) not less than six times the overall diameter of an individual cable, and (b) not less than the overall width of an individual circuit, except that the horizontal clearance may need not in any case exceed 150mm.
  2. If the number of circuits exceeds 4, they are installed in a horizontal plane. However, for installation conditions other above, current rating factors incorporated in IS 3961 Part II please be applied.

The following points should be taken in to consideration before selecting any particular size and type of cable:

  1. The system of power & voltage source where the cables are being used.
  2. Conditions of installation at site.
  3. Current carrying capacity of cable.
  4. Voltage drop of cable.
  5. Short circuit capacity of cable.
  6. Availability of the selected size of cable.
