Re: under-cabinet lights
Sam, I see what you mean. I had a heck of a time editting that.

Took me a little research to find but the reference you have made to the audio racks in 640.21 clearly shows that the cord and plug or directly connected is to relieve the use of a disconnecting means.
JW that section has nothing to do with the disconnecting means.Originally posted by jwelectric:
Mr. Bob
You are talking about audio cables in 640.21 and the term direct connection in lieu of a cord and plug is to say to not confuse the cord and plug as a required disconnecting means.
Audio cables do not connect to a premises wiring system.640.21 Use of Flexible Cords and Cables.
(E) Between Equipment Racks and Premises Wiring System. Flexible cords and cables shall be permitted for the electrical connection of permanently installed equipment racks to the premises wiring system to facilitate access to equipment or for the purpose of isolating the technical power system of the rack from the premises ground. Connection shall be made either using approved plugs and receptacles or by direct connection within an approved enclosure. Flexible cords and cables shall not be subjected to physical manipulation or abuse while the rack is in use.
That is not the answer to the question, a yes or no would have been an answer.Originally posted by jwelectric:
I did answer his question so this tells me that you must have a problem reading.

this is not totally all of the dispute.
JW, you don't see this as meaning "cord-and-plug-connection" is one method, and "direct connection" is a different method? How would this sentence be logical if the two phrases meant the same thing?Connection shall be made either using either using approved plugs and receptacles or by direct connection within an approved enclosure.
They do not use the term, "direct connection."Receptacle. A receptacle is a contact device installed at the outlet for the connection of an attachment plug.
This definition makes it clear that the wiring of a structure ends at the outlet. They explicitly state that the wiring internal to the luminaire is not a part of it.Premises Wiring (System). That interior and exterior wiring, including power, lighting, control, and signal circuit wiring together with all their associated hardware, fittings, and wiring devices, both permanently and temporarily installed, that extends from the service point or source of power, such as a battery, a solar photovoltaic system, or a generator, transformer, or converter windings, to the outlet(s). Such wiring does not include wiring internal to ap-pliances, luminaires (fixtures), motors, controllers, motor control centers, and similar equipment.

The requirement for sizing the overcurrent protection in a supervised fire pump disconnecting means to be able to carry locked-rotor current indefinitely is a key factor in the reliable power source equation. Due to the critical life safety and property protection function of a fire pump, opening of the circuit by an overcurrent device installed between the point of connection to the power source and the fire pump controller cannot be tolerated and has to perform as if there were a direct connection to the power source . A change in the 2005 Code clarifies that sizing for locked-rotor current applies only to overcurrent protective devices and does not extend to conductors or other devices in the fire pump motor circuit. Similar revisions to clarify this point are made in 695.5(B) and 695.5(C)(2).

I agree with Bob (iwire). This section does not say anything about plugs and cords. It does not tell whether or not a ?direct connection? includes plugs and cords.Originally posted by jwelectric: Using the fire pump in 695.4 that we all are familiar with I think will work best.
It is not explained at all in 240.20(A). That paragraph does not contain the word ?direct,? nor the word ?indirect,? nor any word or phrase that has a meaning similar to either word. It does not mention plugs and cords. All it has is the word "connected," without being associated with the word "direct." You would be stretching our language far too far, if you were to suggest that using the word "connected" in the absence of the word "direct" conveys the intent of distinguishing "direct" from "indirect."Originally posted by jwelectric: To find the definition of direct connect lets find out what is indirect connect. This is explained in full detail in 240.20 (A).
I submit that you have proven nothing.Originally posted by jwelectric: Now I have proved using code . . . .
