    Re: CQD answer published Wednesday, November 27, 2019 - 2020 NEC Emergency Disconnects

    1) AGREE with KEN.. it’s a Stupid idea some engineer came up with brought it to other engineers and over thought the process and added it to the 2020 code. WE ALL Still have time to voice out public objections on the 2020 NEC Bill Schell

    2) "The concerns you express about burglary and mischief can be dealt with by locating the disconnecting means outside and locking it in the on position but locating the panelboard inside the building. The really evil people will find a way to defeat everything. The benefit to having the disconnecting means outside is for emergency responders so they can deenergize the interior wiring before entering the building." If it's locked in the on position, how do 1st responders deenergize it? Dave

    3) Thanks for all your hardwork keeping us all on track. The poster that responded to the Nov 8 discussion on placing of breaker boxes on the exterior may be failing to understand what I believe to be the best reason to do so. The main breaker being accessible from the exterior favors when the fire department is dispatched to the building. First thing they do is to shut power down for safety reasons that I don't think needs to be explained. As you said, those "bad guys" will access a panel if they are in or outside the building if there intent is to disconnect security. Happy Thanksgiving to all! Jeff Frishof
