Electrical Receptacle Wiring in Parallel vs Daisy-Chained Wiring in Series or Daisy-Chained vs. Parallel Receptacles Daisy Chain Wired Receptacles - wiring in series.

Receptacles: Series or Parallel? - JLC-Online Forums Oct 26, 2005I read somewhere that parallel is better because if a receptacle fails, it won't affect others downstream. From practical experience I have come to prefer wiring in series, for several reasons. 1) Faster, 2) Less wire in box, 3) No possibility of wire nuts coming loose, etc. To me these benefits outweigh the advantages of parallel wiring.
