Comment on Question and Response for February , 2020: Good Morning.
This is almost always my first read of the day.  Keep up the good work.

Regarding the answer for the CQD for February 4.  I think it’s important to note that although Section 440.14 says the disconnecting means must be in sight there is one more step in this process.  It should be noted that in Article 100 “within sight” and all other variations of it are defined.  The equipment must be visible and not more than 15 meters (50 Ft.) distant.




Hi Stan, great to hear from you and thanks for the comments. Yes agreed, it is important for Code users to understand the definitions and how they provide needed clarity and support of requirements. The NEC defined  terms "in sight from" "within sight from" and within sight" are such defined terms. The equipment has to be visible and not exceed those distances.
