Rubber electrical grommets help protect intact cable insulation at a specified opening. They are one part of an electrical installation and do not replace grounding, overcurrent protection or suitable cable insulation.
Match the cutout, panel thickness and cable dimensions to the drawing. Confirm any required sealing, strain relief or electrical properties using the relevant specification.
Color may support an agreed identification scheme, but it does not establish an insulation rating. Choose the compound for the operating environment and verify the installed part. Address damaged wiring or unsuitable equipment through the appropriate repair rather than relying on a grommet alone.
