Chris,

Let's proceed from here. Will you explain the exceptions?

Wrong choice of words on my part sorry, I just wanted everyone to know that in order to use a 20 amp receptace on a 15 amp circuit you must first be using a single receptacle on a individual branch circuit...

2 quick questions about recepticles


I guess where my brain is twisted is on my exp. wiring the typical dwelling unit . I always ran a dedicated 20A rect to beat the GFCI rule in basements. Rule goes away in '08. My head hurts.

2 quick questions about recepticles


So now that the great debate is over, can anyone else weigh in on the issue of why recepticles aren't designed with 2 ground screws to feed through like the hot and neutral?

Its already been answered, because of a continuity issue.

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

I understand you answered this from a CODE standpoint. That is not what I am looking for. I want to know from the people who work in the trade as to why it was never developed this way in the first place.

I guess I am not going to get anywhere with it.

2 quick questions about recepticles


With the ground back to the panel and the continuing ground on separate screws, it is easy to break the ground continuity without thinking about it and forget to reconnect it. Whereas with the ground wires fastened directly to one another, disassembling the ground at least has to be a conscious and pro-active maneuver.

It is true that all ground wires coming into a box are to be tied together. Still, it is required that in new construction that a ground wire accompany the feed in the same cable or conduit back to the panel as opposed to relying on a ground going back to the panel via a different physical routing.

I work in the trade, and to answer your question as simple as I can, because its a dangerous method. and the NEC would never allow it to be developed that way.

Coincidentally- this is the same reason I like to use pigtails for continuous runs of hot and neutral as well rather than the separate screws.

2 quick questions about recepticles


"Low impedance path"


That is our goal as pro's. How can I, as a pro who understands Grounding and Bonding, speed the path back to the source in the case of a ground fault? I work very hard at it. Continuity is key.

I have a problem with the new MC all purpose. You don't technically have to bond a device if you remove the retaining clip on the device or purchase self grounding devices. I see continuity issues here. Granted, It would never be a danger if we all LOTO.
