I roughed in under and over cabinet lighting and each with its own switch. I ran a wire from each fixture to my basement. One wire to power each switch and one wire from the switchs to the basement as well. I used two junction boxes to tie all my wiring in, one for over one for under. Power comes into the over and hot wire tied with power to switch and power to under cab switch. All neutrals together and all grounds together. Power went to the switches, neutrals tied together in box and out of the switch in the basement junction boxes the hot wires connect to all the other hots turning on all lights when switch is on. To check my work I took the power supply that will be coming from the pannel and just stuck the hot and neutral into a gfi next to my pannel. Using a basic light tester all my wires were hot after the switch without the switch being hooked up. Could the electricty been picked up by the ground wire and flow all over since the ground was not connected to the pannel or the GFI? The box and all was hot. I then wired a 3 prong male end to the same wire and properly plugged it in to the gfi and my problem went away which is good. But I want to make sure that sounds ok because if not I will have to address the problem. I am 99% sure everything is wired up correctly but things happen. I didnt think that just by not connecting the ground to the pannel that would happen.
