    Try Part 5, chapter 52.

    And Chapter 54.

    Although, Appendix 4 has a more complete set of advice.

    Cable size also affects voltage drop and whether ADS is achieved.

    and 433/434 - sometimes it's a case of matching the conductor to the protective device characteristics rather than vice-versa.

    and 534.4.10 if SPDs are involved.

    or being pedantic 132.6 - as most of the others flow from that.

    132.6 (ix) and cost constraints.
