How much is too much?

I am wiring an upstairs remodel project that will be inspected when the rough in is complete. I have pulled all my wire into the boxes, but I have a tendency to pull heavy. Some of my boxes have over a foot of extra wire hanging out. I used large capacity plastic boxes so I have plenty of room. I was just wondering how much is actually too much to leave?

Excess for inspection....I think 6" beyond the outer box is all that is required
I usually leave around 8", some cases more - if its the only wire in the box

Excess to be able to fit in the box is another matter
Only 1 wire 12" will probably fit, 2 wires more difficult
3 or more...depending upon #12 or #14 may not fit 12" for each

If you can't fold the wires in the box neatly then you probably have to much. I like leaving extra(8-10"), nothing more frustrating then going into a box where the wires are only 2 inches long.

Most case 6 to 8 inches useally work fine for single and two gang box but before you go that route you will need extra length of conductor due you will have to tie the ground conductor together and fold it first so you have pigtail sticking out nice.

Then do the netural conductor { useally white } next and wirenutted if in switch box and fold it back neat otherwise leave it out for dupex recpectale { that will depending on single or multigang box } then the last is hot conductor you may end up make multi pigtail if have couple switches or receptales.

If you are dealing with GFCI please pay attetion to the line and load side that part will save your headache down the road if not done right.

Wire length

Code requires min. of 6 inches at each box but must have min 3 in out of box fro device connection. Hope this makes sense.

You can leave some of the cable slack inside the wall.

You can trim the end of each conductor to about six inches after fastening the cable to the studs and stripping off the jacket for the portion entering the box. Box clamps should hold onto the end of the cable jacket, not just the conductors.
Stop some of your bank autopayments so you can set priorities for manual monthly payments out of your coronavirus stimulus check.
