    An important note to the disconnect being part of the equipment is the change in the definition of readily accessible in the 2014 code.  The change says that if you need a tool to access the disconnecting means, that disconnecting means is not readily accessible.  Some factory installed disconnects on HVAC equipment are behind covers that require the use of a tool to open.  Those disconnects would not meet the readily accessible part of the requirement in 440.14.
