NAICS 238210: Electrical Contractors and Other Wiring Installation Contractors

Specialty trade contractors primarily engaged in installing and servicing electrical wiring and equipment. A core specialty trade for federal building and base contracts.

What this NAICS code covers

NAICS 238210 is the North American Industry Classification System code that federal contracting officers assign to electrical contractors and other wiring installation contractors work. The code determines your small-business size standard for any solicitation issued under it, which in turn determines whether you can compete as a small business or pursue any of the socioeconomic set-aside programs.
