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

What is the difference between stock tickers UN and UL?
Unilever is a dual-listing, Anglo-Dutch company. The company, therefore, has two listed stocks. UN is for the Dutch-listed stock and UL is for the UK-listed stock. The material difference is that the dividend from Dutch-listed stock is subject to Dutch tax law and the dividend from UK-listed stock is subject to UK tax law. From practical standpoints, because of the different withholding, UN seems to have greater tax burden than UL which resulted in UL typically traded at higher price than UN. A similar situation is Royal Dutch Shell, RDS.A is subject to Dutch and RDS.B UK dividend rules. Exchanges rates between three currencies (USD, EUR, GBP) might have impacts, too.

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.
