What is a UL ratio?
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.
Is a machine UL approved if most of the componets are UL listed or does it need to be teasted as a whole for overall rating and UL approval?
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

Does UL approved mean fire resistant?
Not necessarily ... It depends on the product and the safety standards involved. UL approved simply means that the testing agencies Underwriters Laboratories (UL) or Underwriters Laboratories Canada (ULC) tested the product against safety standards. Underwriters Laboratories tests all sorts of products for all sorts of safety hazards. Presumably, if fire is a safety concern for the specific product tested, the approval would mean that the product met some sort of fire resistance standards.
Which is a better electrical cable to wire up your home Finolex or Havells?
All electrical wiring products in North America have to be UL or CSA approved. These are an independent testing laboratories that test products to destruction. The product is then given a range in which the product can be used. When you are looking for electrical products check for the UL or CSA approval stamps. If it is not on the product do not use it as your insurance company will use the non approved product clause if you make a claim on damage that the non approved product caused. Electricians can be fined if caught connecting non approved products. Be aware that there is a lot of off shore counterfeit products in the marketplace.
