Asked in Modification of Old Electrical Work
Can you split 1 wire into 2 within a junction box or must you only add on to the end of a electrical run?

you can. the current draw is the same either way. im almost sure (check me) that everything in a house is wired "in parallel", whether its outlets or lights. so adding the extra wire in either place splits the current the same way, just in a different spot. the only reason you wouldn't split inside a junction box is if the box is too small to hold all the wires and connectors.
