![]() ![]() I assume this means that power is coming in from one of the overhead lights, and not into the boxes- would this be correct?.That box is shared with a simple on/off light on a separate circuit and no wires are shared. On the box by the exterior door, the red wire, black with white paint, and white are all hot. This box is shared by a functional three-way zwave switch to the stairs light. There are also two 2-wires o' mystery that are just connected to the hot pigtail (black) and neutral pigtail (white) and sit in the back of the box, silently taunting me. Another black/white-paint wire from a separate romex was originally wired to the common screw of the original three way I removed because the switch had cracked. There is a 3-wire romex for the overhead lights, where the red wire is hot,Ī white wire is hot, and a black wire with white paint is hot, although it goes to a hot pigtail. On the box at the base of the stairs, there are three 2-wire entries, two of which go to a black/hot pigtail and white/neutral pigtail. In both boxes, all three wires in one of the 3-wire romex cables coming into the box are hot. In both boxes, 3-wire goes to the switch with common and two travelers. I know of two switches that control our basement overhead lights. However, there is a three way in the basement that has me scratching my head. Most were simple like three-way switch common/traveler swaps. I just moved into a new house and noticed several electrical gremlins that I've been picking away at. Ultimate goal is to install a zwave switch on this circuit, requiring me to identify hot, load, traveler, and neutral. However, is this set up okay if I just want to test how a 3 way works? Every time I finish with it I disconnect my devices and shut off the breaker controlling the loose 14-2 rough in.Need help identifying wires and solving a mystery of everything being hot. This is just an experiment and in no way would I wire it this way behind drywall as a permanent fix. I used a black hot wire as my switch leg between the second switch and my light. I used a white neutral and black hot that I spliced separately from a new spool of 14-2 to use as my travelers to the second switch, and ran the neutral from the existing 14-2 to my light between the two switches along with a ground. My set up starts with the power entering the first box and connecting to the first switch, then to the light, then to the last switch. I didn't have any 12 or 14-3 wire bundle to wire my switches or light so I used 14-2 instead. My power source is a 14-2 hanging loosely from my basement floor joists which is connected to the breaker via a 15 amp breaker. I was doing an experiment in my basement to try and set up a makeshift 3way mounted on some wood planks so I could learn a bit about how a 3 way works. The hot is extended from the light's box to one 3way and the switch leg is extended from the light's box to the other 3way. Level Advanced Also called "Power at the Light 3way" or "Commercial 3way"ĭescription Power at the light's box with 2 dead end 3ways. If you miswire the travelers you might have to go back up a 12 foot ladder and take down a 50 pound chandelier to access the connections in the ceiling light box unaware that one of the wires will still be hot. This method also creates an electrical hazard beginners will think the wiring in the light box is dead when the light is switched off, but one traveler wire will still be hot unless the circuit breaker is turned off. If you have a choice, choose the switch box for feed and traveler connections with only the switch leg connections at the light. It would be easier to work on your keyboard (and electrical connections) at a switch location rather than up on the ceiling. If you were given a choice to move your computer keyboard to one of 2 locations which would you choose ġ) Upside down, up on the ceiling by the light or. ![]()
