Continuity of Circuit

[Trey4U]

I'm fairly certain this is in the Code but for the life of me I can't find it. :? Basically that a circuit will not rely on a device for continuity. (Wiring into and ouf of a receptacle by the screws and not "pig tailing" the wire to feed the receptacle) Code reference?

Thanks!

must pigtail if it is a MWBC. don't have codebook handy to look up

Myself, I find the Wiring Methods article has a lot of handy information. in this case, check out 300.13(B):

300.13 Mechanical and Electrical Continuity ? Conductors.
(A) General. Conductors in raceways shall be continuous
between outlets, boxes, devices, and so forth. There shall be
no splice or tap within a raceway unless permitted by 300.15;
368.56(A); 376.56; 378.56; 384.56; 386.56; 388.56; or 390.7.
(B) Device Removal. In multiwire branch circuits, the
continuity of a grounded conductor shall not depend on
device connections such as lampholders, receptacles, and
so forth, where the removal of such devices would interrupt
the continuity.

Similar requirement for equipment grounding conductors and is likely the reason only one equipment grounding terminal is found on devices.

250.148(B):

(B) Grounding Continuity. The arrangement of grounding connections shall be such that the disconnection or the removal of a receptacle, luminaire, or other device fed from the box does not interfere with or interrupt the grounding continuity.
