Motor Disconnects At Sewage Aeration Ponds

I do not remember that, what code cycle allowed that?

The substantiation may prove very interesting and on point in this thread.

The only thing that has changed with the exception is the limitations on its use. Here is how it read in the 99 code.

A disconnecting means, in addition to the controller disconnect as required in accordance with Section 430-102(a), shall not be required for the motor where the disconnecting means for the controller is individually capable of being locked in the open position.

The exception was changed for the 2002 code to substantially what is it in the 2011 code. The real change is the limits as to where the exception could be used. In the 99 and earlier code it could be used anywhere.

Of course, and just like the motor it serves, the disconnect may need replacement sooner due to the environment.



And so is people taking shortcuts when the disconnect is not right at the equipment.

Did the exception not allow the controller disconnect to be the motor disconnect if lockable? You said you didn't remember that then followed up with same information you were disputing.
