Whenever I install a disconnect for a roof top hvac unit I'm always told to install a fused disconnect. Would it not be to code to install a nonfused disconnect as long as a hacr breaker is installed in the panel? 440-52(a) seems to tell me I only need one means of protection and 440-52(a)(3) says an inverse time breaker can be used as long as it matches the nameplate rating.Thanks for any thoughts and if possible refer to the 99 code if you can.
