Leaving unused wires in panel

I have five 12/2's and one 14/2 that I ran to areas of the house for later use. They come out of interior wall with panel on the outside wall just opposite. Can I put these wires in the panel? If I sell the house before I use them will an inspector have an issue with this? They would come through the back of the panel through a 2 1/2" conduit near the bottom and go up the side tucked behind other wires. I can mount a box on the interior wall and just store the wires in their if I have to.

First of all how long is this 2 1/2" conduit,is it just a nipple ? as far as leaving the cables in the panel ,that should not be a problem, leave them with the outer jacket stripped off, make sure the black and white from each cable are taped together to better ID the cables for future use, you could also connect the bond wires to the ground buss if you like to help make things look neater.

PC is trying to explain that each cable needs to be secured within a certain distance of the enclosure. Merely running them through a piece of conduit does NOT make them secure.

IF the conduit is less than 24 inches in length then no derating of the conductors is necessary, that is the reason for asking how long the conduit.

Yes, you probably should have a box on the internal wall to hold these cables. Even better would be to use a continuous piece of conduit between the box and the panel enclosure and then use individual conductors. Since this is for future use, a box with a continuous conduit would not even need the conductors until that future usage became viable.

If you leave the cables then they should have a tag (paper) describing where they go and for what purpose affixed to the cables in the panel enclosure.

The code only allows that arrangement with a surface mounted panel and the sleeve needs to come out of the top of the panel. There are other conditions also.

PC, could you offer a code citation? Article and paragraph? Not saying that you are wrong, I just want to see it myself.

Here it is:

From 2011 312.5(C)

(C) Cables. Where cable is used, each cable shall be secured
to the cabinet, cutout box, or meter socket enclosure.
Exception: Cables with entirely nonmetallic sheaths shall
be permitted to enter the top of a surface-mounted enclosure
through one or more nonflexible raceways not less
than 450 mm (18 in.) and not more than 3.0 m (10 ft) in
length, provided all of the following conditions are met:
(a) Each cable is fastened within 300 mm (12 in.),
measured along the sheath, of the outer end of the raceway.
(b) The raceway extends directly above the enclosure
and does not penetrate a structural ceiling.
(c) A fitting is provided on each end of the raceway to
protect the cable(s) from abrasion and the fittings remain
accessible after installation.
(d) The raceway is sealed or plugged at the outer end
using approved means so as to prevent access to the enclosure
through the raceway.
(e) The cable sheath is continuous through the raceway
and extends into the enclosure beyond the fitting not
less than 6 mm (1⁄4 in.).
(f) The raceway is fastened at its outer end and at
other points in accordance with the applicable article.
(g) Where installed as conduit or tubing, the allowable
cable fill does not exceed that permitted for complete conduit
or tubing systems by Table 1 of Chapter 9 of this Code
and all applicable notes thereto.
