To calculate the nominal diameter of any concentric-lay-stranded conductor made from round wires of uniform diameters, multiply the diameter of an individual wire by the applicable factors listed below:

Number of Wires in Conductor | Factor to Calculate Conductor Diameter |
---|---|

3 | 2.155 |

7 | 3.000 |

12 | 4.155 |

19 | 5.000 |

37 | 7.000 |

61 | 9.000 |

91 | 11.000 |

127 | 13.000 |

169 | 15.000 |

217 | 17.000 |

271 | 19.000 |

For a greater number of wires use the formula:

Conductor Diameter = Wire Diameter x SQRT (1.332 x No. of Wires) |
