About this level

Practical summary

Group 432 sits in the PSIC 2019 hierarchy under F Construction > 43 Specialized Construction Activities. This group usually narrows the choice to a small family of classes such as Electrical installation, Other construction installation, and Plumbing, Heat and Air-conditioning Installation. It is useful when two or three neighboring activities look similar but should not be collapsed into one code.
