The NEMA or industry standard symbol for a light is shown at which location?

The NEMA or industry standard symbol for a light is designated to indicate the typical or appropriate placement for lighting fixtures in various environments. Location I, as identified in this question, represents general installations where standard lighting equipment can be used effectively. This location typically pertains to areas with controlled conditions, such as commercial buildings or spaces where the fixtures will not be exposed to harsh environments.

In contrast, other locations such as II, III, and IV typically indicate specific conditions that may require different types of lighting fixtures or installations. For example, these locations may apply to outdoor settings, harsh industrial environments, or other specialized scenarios. Each of these designations is created to ensure that electrical components, including lighting, function safely and efficiently in their surrounding conditions.

Thus, the correct answer reflects the standard placement of light fixtures in suitable environments, making it clear that Location I corresponds accurately with the NEMA symbol for lighting installations.
