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. Table 1 applies only to conduit or tubing systems [Note 2].7- Lookup tables, 8- Excel spreadsheets. And I explained the first two methods in this Article. Also, In Article " Voltage drop calculations- Part Two", I explained the third method: U.S Method and today I will continue explaining how to use Chapter (9) tables method for Voltage Drop Calculations as follows. 3.2 NEC Chapter 9 – “Tables 8 ...
