It is safe to "tie into" an existing circuit, and if you want to get
technical, it really matters what the main circuit is used for.
If the 2 receptacles are on a high watt appliance say, and you want to run
another, it may pop the circuit.
More than likely not, and you are fine. Most of the times many of the
receptacles on any given circuit are not being use.
rarely are they ever on all at the same time unless a workshop, business,
lighting, computer, tv...
So, I would put in a junction box, and pig tail the circuit coming in and
going out to allow the original circuit to be operating, and then using the
pigtail, tie into the new receptacle.
Make sure the grounds are all the same, the neutral, and of course the hot.

I don't frequent any other forums and have a basic electrical question so
thought I would try it here.
When I look at circuits for outlets they always run the wire "through" every
outlet until the end. Is it OK to just branch or T off of an existing
I have an outlet at each end of a wall. There is romex running across the
top of the wall from one to another. It has some slack. I would like to clip
the romex, add in a junction box and tie in one piece of two wire romex
running down to a new outlet box and splice the clipped ones back together
so the original ones keep working.
If I follow all the circuit maps I see and the traditional way I see
circuits done I would clip the romex, run one piece of two wire down to the
new outlet from one side of the clip. Then come out the other side of the
outlet with more romex back up to the other side of the clip so the circuit
runs "through the outlet, instead of branching.
I know branching works because I have done it a few times before.
To code? Don't really care, just wonder.
Safe? Do care.
Of course I also run the ground wire as well.
