No UL has many different listings and requirements, but it does not mean something is intrinsically safe.
Yes. According to UL Standards 486A and 486C, wire ferrules need to have UL approval. FerrulesDirect is the only company in the U.S. that offers UL approved ferrules See UL File #E326725.

No…..The luminaire ballasts run at 140KHz and comply with EMC,FCC, UL, and CE regulations with non-interference under normal circumstances. The regulations are in place to protect navigation and radio communications and the system will not interfere with portable or cellular/mobile phones.
If you mean UL Rated, that is an abbreviation for an electrical product being approved by the Underwriters Laboratories as safe to use or have. If you buy a space heater, for instance, that is not UL Rated and does not bear the stamp that it is UL Rated, I wouldn't recommend using it.
Yes, there is a difference between ETL listed and UL listed products. ETL is a mark from Intertek, a testing laboratory, while UL is a mark from Underwriters Laboratories. Both marks indicate that a product has been tested for safety, but they come from different organizations.
UL stands for "Underwriters Laboratory." Electric devices labelled "UL Approved" are safe to use in your home.
yes
that it has been tested to the NFPA 10/UL 711 standard and that it has passed the class A, B and C test requirements to be listed as such.
I assume you mean is it safe. Look for a UL (Underwriters laboratories) listing label on the equipment . That means it has been tested to a safety and performance standard for that type of equipment. There are other recognized test labs too. I reputable company will get its product listed.
ETL and UL are both certification marks for electrical products, indicating they have been tested for safety. UL is a more widely recognized certification, while ETL is newer but also reputable. Both certifications ensure that electrical devices meet safety standards, but UL is more stringent in its testing process. Having either certification indicates that a product is safe to use, but UL may provide a higher level of assurance.
A machine is UL approved (the correct phrase for an end-product is 'UL listed') only when UL has successfully investigated the complete machine construction and carried out any tests they deem necessary from the relevant UL standard.The investigation process is much more straightforward if all the safety related components are 'UL recognized' (the 'backwards 'UR'letters symbol you may have seen on e.g. relays, ICs, MOVs and suchlike). You must use UL recognized components from the correct category and observe the component's UL conditions of acceptability (e.g. UL voltage and current rating for terminal blocks).Hope this helps!John ShowellProduct Safety ConsultantProduct Approvals Ltdwww.productapprovals.co.uk
A UL fire alarm system is a fire system that has been installed to Underwriters Laboratories specifications and is certified by that same group. The system is inspected by a UL certified inspector on a regular basis and the system must at all times adhere to the UL standard. Any changes or modifications to the system must be UL approved. All of the alarm equipment must be UL certified as well. If the fire system is monitored by a Central Station, the Central Station must also meet the same stringent requirements in order to monitor the signals. The Central Station is also inspected by a UL inspector on a regular basis.
