there was a proposal for the 99 or the 02 that addressed manual starters, it indicated that some manual starters (controllers) did not provide adaquate gutter space to be listed as a disconnect. also disconnects are subjected to a list of tests that a unlisted manual starter is not subjected to.
. A manual starter may be a disconnect if it is so listed as I understand it.

I agree a motor controller requires a disconnect in accordance with 430.102(A) The original question ( I Believe) addressed appliances and a still regard article 422 as the king pin in most appliance installations. the breaker is allowed to serve as a disconnect if it is within sight and if not if the means to lock it is inplace with or without a lock. The 05 Code also made a like change to 430.102 and again in 440

"430.111 Switch or circuit Breaker as both Controller and Disconnecting means."

"(A) General The switch or circuit breaker complies with the requirements for controllers specified in 430.83, opens all ungrounded conductors to the motor, and is protected by an overcurrent device in each ungrounded conductor(which shall be permitted to be the branch-circuit fuses). The overcurrent device protecting the controller shall be permitted to be part of the controller assembly or shall be permitted to be separate. An autotransformer-type controller shall be provided with a seperate disconnecting means".

It seems to me that the switch in the example you give is both and this section seems to say we don't need another disconnect unless it is an autotransformer-type controller. Provided the switch meets the requirements of 430.83.

What do you think???
 
i gotta go but the style manual does not advocate general references such as section 9 of 430. this needs to change I think that the ref to this section is more for 430 109 and 110 kinda rather than 102 but I'll look into it Gnite

the sox won

I just looked at the handbook, it says

"..... It is the intent of 430.111 to permit omission of an additional device to serve as a disconnecting means.
Note that a separate disconnecting means must be provided if the controller is of the autotransformer type or compensator type....."

The disconnect that this section is referring is to serve the controller , is it not??
 
I don't understand the bit about the autotransformer type controller requireing a separate disconnect , it seems as if this section is referring to the disconnect for controllers and not motors.
 
Ryan I see your point , after about the 20th time reading that damned section.
Thanks.

I just find it hard to believe that this has been overlooked for all these years.
 
I still say that in reading the definition of disconnecting means in Art 100 that the single pole switch in the disposal circuit is a disconnecting means and not a controller.
If any thing needs to be massaged, it is the definition of controller in Art 430.
 
I still don't understand why 430.111 seems to require a disconnect for a specific type of controller . But does not ommit the requirement for others????

An autotransformer-type controller shall be provided with a seperate disconnecting means".

The above controller requires a separate disconnect . Separate from what?... the attachment plug...It seems they all do??

If 430.11 offers no relief why does it mention a specific type of controller needing a separate disconnect
