[QUOTE="John Roberts, post: 124672, member: 126"] Re: Crest Pro Lite 7.5 In my experience UL does not ASSume, they certify designs as safe, so the light fixtures are well tested. Even things like the line cords used are specified and certified. That has not been my experience. Hopefully you have the UL file number for that OEM amp module, where UL tested and certified it as safe without a fuse/breaker. There are different ways to skin any cat, so if the amp can safely operate w/o a line cord fuse/breaker it's all good. FWIW with modern amps the resettable mains breaker is more a short term power limiting device than used for human safety. The transformer will probably have an internal thermal fuse for when the breaker fails hard on (they can do that). I have had my share of knock down drag out battles with UL over things as simple as what line cord I use on a 3kW amp, which is modest power by modern standards. JR [/QUOTE]
