I would like to add a recessed light, a couple in fact, in the ceiling of my 1st floor study. For a short time I have access from above because the flooring is being replaced on the second floor. The problem i have is that there is a wire, 14/2 nm, running through the joists on its way to a 2nd floor wall outlet and it would end up touching or an inch away from the can. Doesn't feel right. Replacing the whole thing would be very painful as this is an existing install and i do not plan on cutting into 2nd floor walls. Is it acceptable to cut the wire and splice in another 24 inches or so using a junction box at each end and wire nuts? That would be enough to avoid the light can. I think the wire feeds a single 15 amp dual-outlet but there may be two.
