One of my students challenged me today and said that he was told by an electrician that the terminals on a receptacle could not be used to continue the run. In other words use the receptacle to splice the hot and neutral in a 120V circuit.
I am aware that the neutral terminals on a receptacle cannot be used to carry a common neutral when two circuits are involved but I cannot find anything in the code that precludes someone from using the terminals to continue the circuit.
Additionally I do realize that the device is the weakest part of the circuit and that not using it as a splice has its advantages but I am strictly interested if it is against the code to do it.
UL 'White Book' 2003 edition: Category RTRT (receptacles) "Sgl & duplex receptacles rated 15A and 20A that are provided with more than one set of terminals for the connection of line and neutral conductors may be used to feed a single set of branch circuit conductors connected to other receptacles on a multi-oulet branch circuit."

I think this is a rehash of the "pigtail v. no pigtail" argument of years ago.
Ask him how he would remove the receptacle for service (on a temporary basis, of course), but keep the "downstream" circuit live, without cutting, stripping, and joining the conductors.
(With the pigtail method, of course, you could simply cap the exposed ends and blank the box - until you return with the correct color receptacle )
BTW, the actual wording for multiwires is
NEC 300-13 ('96 version - it's what I have at the FD) Mechanical and Electrical Continuity - Conductors
(b) device removal
In multiwire branch circuits, the continuity of a grounded conductor shall not be dependent upon device connections, such as lampholders, receptacles, etc., where the removal of such devices would interrupt the continuity.
I'd just use the argument that a good practice should not be limited to a single application, just because it's not required.

Golf junkie, what right does the ahj have require above the NEC? Is that how things work there? Also millions of homes are wired with the receptacle terminals as feed throughs. There is absolutetly nothing wrong with this unless it is a multiwire circuit. Your problem was probably loose connections on the original install.

Doug, The governmental unit that adopts the code can make any changes that they want when they adopt the code. These changes become part of the code for that area. The inspector cannot require more than what the local code requires. If the adopted code does not require that all receptacles have pigtails, then the inspector cannot require this. Don
