Less voltage drop.
Higher amperage available at an outlet.

You are going to have to break out the calculator for me here....a longer length of wire (albiet one size larger) will have less VD than a shorter wire?

Higher amperage....the device is limited to the 15A....how do you squeeze more out the slots? [ T210.21(B)(2) ]


You might also want to consider the cost aspect....screwing #12's vs backstabbing #14's.
 
backstabbing #14's. :roll:

I guess I am old school. Did that once when I was a journeyman and got yelled at for 3 hours while I redid them all. It was my Dad yelling and actually I think it lasted more like a week.

I was right there with you until you went there. :grin:

I may back stab a switch or two. Or I might back stab a receptacle if the feed though was pigtailed under a wire nut but I just can not feel good about feed through on back stabs.

Just a personal preference. :)

What's the crime in back-stabbing?

I certainly will not call it a crime.

It's just I don't consider it as tight a connection as I can make otherwise with screws or wire nuts.

Is it a good enough connection.....very likely yes. :)

Do I think any of my wire nut connections are better....yes.

Our trade is full of this type of issue, what is good enough?

We all have our own ideas what is 'good enough'. :)
 
True...we all have our notion of "good enough".

I'm sure you have also come after someone who thought "good enough" resulted in a wirenut practically falling off...and no twisted wires also.

Without a doubt. :)

I fried a surge supressor when someones 'good enough' splice came off of the neutral of a MWBC.

Kind of glad the surge strip let out the smoke instead of new Apple computers pluged into it.:grin:

The farthest receptacle is the same distance from the panel no matter which size wire you install.

Good point!

Lucky for me, I'm not in the position that the extra few seconds cannot be afforded.

Not really.

The 20 amp circuit has more receptacles on it, more receptacles will result in more wire under typical conditions.

True, but how much more? Depending on how you run your wire, I'd guess less than 20'. Now what % is that of the overall run to the farthest outlet? How does that extra 20' affect VD?

Call it 20, either way the load on the particular circuit is likely to be less.

I also really don't care much about voltage drop in a dwelling unit. What I do care about is not tripping the breaker.

I guess our major difference is that I am expecting multiple smaller loads and you want to be prepared for one big load. :)

Six of one, half dozen of the other. :)

To each their own, there is certainly no correct answer.
