The wiring is secured to the wall within 12" on the wire that goes to the junction box in the picture; but I do have quite a bit of extra wire. Is it a huge deal to have too much extra? The other wire goes to the outlet in the floor and I didn't have access behind the wall to secure within 8" of the box. However, looking at the picture again, it sure would have looked cleaner to have secured that wire to the wall in a few places. Is it something I should pull the panel off for to fix, or just do better next time?
