Yes. From time to time, a testing agency may list an electrical product that may be in violation of the electrical code, and sometimes in violation of the safety test standard that the equipment supposed to be in compliance with, or evaluated to the incorrect safety test standard. In these cases, when such a product is discovered, the testing agency is notified to take immediate corrective action. If in the opinion of the Department, the equipment is considered to be of eminent hazard to the public or the property, or if the testing agency is nonresponsive to the Department request to resolve the problem, the equipment is not permitted to be installed or energized until the matter can be resolved.

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.

According to Electrical Code article 100, an equipment or material that is tested by an approved testing agency meeting appropriate designated standards are considered as listed equipment, provided that also, the testing agency publishes a list of these products and the product bears the listing mark or logo of the testing agency.

Electrical equipment that is evaluated and tested by the City of Los Angeles Electrical Test Lab conforming to the requirement of the adopted standards and codes are considered as approved equipment.

Listed or field evaluated equipment that are tested and listed or field evaluated according to recognized standards as specified for each testing agency are considered as acceptable. You can find these standards as follows on our "Electrical Test Lab (ETL)" page under "Publications":

• Standards for testing agencies that have approval for listing of equipment
• Standards for testing agencies that have approval for one-time field evaluation

According to the City of Los Angeles Electrical Code section 93.0402, as well as section 110.2 of the State of California and National Electrical Code, only the conductors and equipment required or permitted (by the code) are acceptable when they are approved.

If an unlisted electrical product is inadvertently installed in the City of Los Angeles, the installer can request for a field evaluation of the product from the City of Los Angeles Electrical Test Lab or from a recognized testing agency, however, the equipment would not be permitted to be energized to operate until either an approval is obtained from the Electrical Test Lab, or an acceptable field evaluation by a recognized test lab is completed and a satisfactory report is submitted to the Department electrical inspection in order to obtain approval from them.

The rules and regulations of LADBS-ETL are provided in Information Bulletin P/EC 2014-005.

7. For new model with unlisted transformers, drivers or power supplies with a rating of less than 1KVA, provide two samples with schematic wiring diagrams and specification sheets.

The general and laboratory approval is good for 12 months. The product approval letter indicates the duration and expiration date of the approved product.

One-time approval is good for the duration where the equipment is installed, provided that the equipment is not modified or relocated to another location in or outside of the building or facility.

No. Unless it is part of equipment approval by the LADBS-ETL with prior approval, provided that the testing is witnessed by the LADBS-ETL and the test program and equipment have already been approved by the LADBS-ETL.
