![]() ![]() I agree splitting a 14/3 for a light and a receptacle is not a great choice, but it sounds legal enough, providing the two lines are on opposite phases on tied breakers. ![]() It may depend on the exact kind of clamp. I think the two 12/2 should not both be entering through the same cable clamp, as I believe we're seeing. The second terminal on the neutral side is only for if you've split the receptacle. In fact Canadian code prohibits using outlet terminals for downstream neutrals, to avoid an open neutral on a hot outlet. It's so that if an outlet is removed (or if one of the connections to it loosens) current from the downstream outlets isn't interrupted. The "other" outlets, the ones with two 12/2 each, may well be daisy-chained off each other, with the cables running from one joist bay to the next above the ceiling.Īs for why they did this with pigtails in the box, instead of using the load terminals on the outlets: that's the right way to do it. Thanks again for any help or clarification you can provide. Is the double pole breaker being used to serve the room lights+plugs and also the washer plug as 2 separate 120v circuits? Why would 14/3 and a double breaker be used instead of just 14/2 and single pole breakers? Why the two runs of 12/2 into the other receptacles? Can I safely use 14/2 to add another outlet from the unused load side of the first plug that previously served the washer? My first thought is that this was a type of multiwire branch circuit but it doesn't seem to fit with what I've read on those either. I'm familiar with running 12/2 and 14/2 to outlets and thought I had a basic understanding of typical wiring but what I've encountered here has me confused and intrigued. There are no wires connected to the load side of any of the plugs. The hots and neutrals are pigtailed together, then connect to the lines on the receptacle. There are 3 other receptacles currently in this room as well, they are all wired as follows: They each have two separate runs of older NMD-3 12/2 wire that come down from the ceiling (currently hidden by drywall) and run parallel down stud bay into each outlet box. ![]() This receptacle was used for a washing machine when the wiring was upgraded, and this is the only reason I can think of why maybe a separate hot wire was reserved for use here? The white neutrals are pigtailed together, and then feed into the appropriate line on the receptacle. The red hot wire from the 14/3 is connected directly to the receptacle line, and the black is pigtailed together with black from the 14/2 wire and doesn't connect to this receptacle at all. The 14/3 from the panel ends at the first receptacle in the room, where it runs into the outlet box along with 14/2 wire from a light switch. The panel was upgraded within the last 30 years or so by a professional electrician and there is modern wire running from all breakers. At the panel, a double pole 15 amp breaker with 14/3 wire is clearly labeled and dedicated to the room in question. I had originally planned on adding an outlet from one of the existing receptacles as part of the renovations. I'm in Canada and renovating what used to be the laundry room in my older house.
