About this level

Practical summary

Group 271 sits in the PSIC 2019 hierarchy under C Manufacturing > 27 Manufacture of Electrical Equipment. This group usually narrows the choice to a small family of classes such as Manufacture of electric motors, generators, transformers and electric generating sets and Manufacture of electricity distribution and control apparatus. It is useful when two or three neighboring activities look similar but should not be collapsed into one code.
