if there is a direct linear chain of 5 residential outlet boxes is it acceptable to tap into one of the boxes in order to run another leg with another 1 or 2 duplex receptacles? if so is it acceptable to take off from the unused terminal screws of the outlet rather than have to redo the existing pigtails?
if there is no convenient existing outlet box to tap into is it acceptable to tap into the wire midway, add a splice/junction box and continue from there with the second leg?
note- the only problem with this is that there is not enough slack in the wire so an additional foot of wire will be required to be spliced to extend to the existing run, meaning another splice box next to the junction box.
thanks for the advice
