In general yes; however, if fraudulent, counterfeited, or non-applicable listing mark or logo is used on the electrical products, or if the installer misapply or use the product for other than its intended purpose, or if the installer does not follow the installation instructions of the product, the Department would treat them as an unlisted electrical product, and will notify the testing agency of the problem. The installer will be required to resolve the matter with the listing agency, or submit the product to City of Los Angeles Electrical Test Lab for evaluation and approval or any other recognized testing agency, or remove the product.
