Note:

1. Maximum permissible conductor temperature under service condition is taken at 70⁰C.
2. Maximum current rating in ground is considered at ground temperature of 35⁰C.
3. Maximum current rating in air is considered at a temperature of 40⁰C.

RW = Round Solid Wire (Conductor)

 RS = Round Stranded Conductor
