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.
