Parallel or series-parallel wiring method is more reliable instead of series wiring.Connecting electrical devices and appliances like fan, outlet, light bulbs etc in parallel is a prefer way instead of series wiring.Switches and fuses must be connected through line (Live) wire.Should I wire multiple lights in series or parallel? Which is better parallel or series parallel wiring?.How are lights and fuses connected in parallel?.What happens when you hook up the bulbs in parallel?.Why would you want to wire lights in your house in parallel?.Should I wire multiple lights in series or parallel?.I may have included things in here you may already know but I don't and others here don't know your skill level or ability working with electric. Once you do all this and get some results we can then guide you a bit better as to what your next step is. And remember, even if you shut off the main breaker the lugs coming into the panel are STILL HOT!! Check the neutral connection at the neutral bar and be sure it is secure.Īgain, do not attempt any work in the panel unless you are familiar with doing so.
If you find any of the let's say receptacles have 120v going from black (hot) to ground but not neutral to hot then you are looking for a loose neutral.Ĭheck the affected breaker, follow where the romex comes into the panel and find the neutral. Disconnect the black from the breaker in question, connect it to another temporarily and see if you then have power. If you are absolutely sure you know what breaker you are dealing with and you are familiar with removing a wire from a breaker try switching breakers. When I wire I never bring in more than one circuit to the same box. This could be because there are two separate circuits coming into one box. When you take apart switch boxes especially if there are more than one switch some people get confused as they find power coming into the box and still the lights/receptacles are still not working. Testing from black to white will not tell you anything as it is probably a switch loop and many people then think that is their problem. I do this first before I start taking apart ceiling fixtures that are not functioning simply because most times it is a switch or receptacle that causes the issue.Īlso when you take apart switches (especially if there is a black and white wire going to the switch) only test from both black to ground OR white to ground. You may find one box that has power coming in to it but not going back out causing the problem. Open each box whether if be switch or receptacle and check your connections there. Again, also check all your connections, wire nuts are tight etc. If you take apart any switches or receptacles be sure you take pictures and or notes so when you put them back together you don't complicate the issue with more.Ī very big culprit is usually receptacles that were installed via "back stab" instead of the conductor being placed under the screw of the receptacle. Then be sure you have voltage on the circuit from the panel (be sure you know what circuit you are dealing with). Doing this first will be far faster and easier in troubleshooting. Find all GFCIs in your home first, be sure they are all reset and have power.
Wire multiple lights one switch code#
Yes, this is not code but this does happen. I have found some homes that have GFCI protection in the bathroom by a GFCI in a garage or basement. You need to let us know how you checked for voltage first.Įven though you do not have GFCI receptacles in the bathroom please check other areas of the house. I have even seen a GFCI in a garage protecting a bathroom.
I have seen set ups where someone wired a GFCI next to the breaker panel, wired to load and ran to a bathroom and to outdoor receptacles to save money by far not to code. Also, approximately how old is this house? Again, a GFCI may be the culprit but maybe not in that bathroom but somewhere else. Please explain how you checked for voltage. Yes, putting the lights on a gfci may end you up in the dark if it trips but also when coming out of the shower or washing your hands and flipping the light switch you could get a shock, so therefore GFCI is handy in that case. I usually give them the option when wiring. I for one does when my customer requests it. Some electricians do put the bathroom lights on the GFCI. Although a circuit for a bathroom may not go to any other room except for another bathroom does not mean someone did not do this. I agree with some others that have suggested this since there is a bathroom involved please be sure (that if there is a GFCI receptacle in the bathroom), that the GFCI did not trip.
