It would be unusual to run across an electrical component that isn’t UL (Underwriters Laboratories) approved, but always check for this tag or stamp of approval on anything you buy, whether it’s a flashlight, power tool, or electrical device. A UL listing is your assurance that the product has been tested for safety. Receptacles, light switches, light fixtures, and appliances all should have UL approval. Keep in mind that UL approval doesn’t imply longevity or ease of installation. A cheaper, lower-end product will never be the equivalent of a more expensive product.
