Electrical – Proper Way to Splice Into Existing Electrical Line

electrical

I'm installing recessed lighting in my living room and want to get power from a line that runs through my attic that provides power for a few other overhead lights in my house. What's the best way to do this?

If I cut the line, I can put this cut inside a work box and then do lots of connections with lots of wire nuts. I won't have a lot of old line to work with, though, and this old line that I cut will have to be reconnected with a short jumper line (there won't be enough slack to reconnect the line to itself after cutting). This seems … "inelegant." With a 12-2 line with ground, this seems to require 6 wire nuts. Is there a better way?

In addition the connection with the short "jumper" cable needs to have two junction boxes. This may seem less than elegant but it is a normal thing.

If the cable to be cut is a long one it may be possible to make the cut in such a way that a part of the existing run can be re-routed to the first added lighting fixture box. Then the wires can be spliced there and the "jumper" can be routed over to near the cut location and spliced into existing wiring at the added junction box.
