Mar 16, 2021 · Table 8 provides that value for conductors ranging from 18 AWG to 4/0. When you go larger than 4/0, the conductor size is expressed in thousands of circular mils (kcmil). A 4/0 conductor is 211.6kcmil, and the next size up is 250kcmil. The NEC does not specify a maximum voltage drop for general circuits.

The reason for that change was table usage was confusing and incorrect usage was a common cause of incorrect conductor sizing. However, those weren’t the only tables in Chapter 9. It still has pages and pages of tables today. The first such table is, not surprisingly, Table 1.Where wet contact (immersion not included) is likely to occur, Class 3 wiring methods shall be used or Vmax shall not be greater than 15 volts for sinusoidal ac and 21.2 volts peak for nonsinusoidal ac. 3. If the power source is a transformer, VAmax is 350 or less when Vmax is 15 or less. 4.Maximum size of conductors – limited to sizes shown in table. Maximum number of conductors: 1.
