I moved in this house 3 yrs ago. Had an electrician install 3 additional lights on this breaker, one with a dimmer switch and another with a motion sensor. For 3 yrs everything worked fine. For last 3 months, I notice at first the lights on this circuit would flicker a little but stay on. Now when the any of the lights switches are on, all the lights that are on will go off and stay off for a while, then go back on. During this on/off period no other electrical switches were changed. (A couple of times I tried turning the swithes on then off, no luck). I checked the frequently used switches and outlets on this breaker to see if there were any loose connections, but there were none. Could the breaker wire be loose? Could a switch or outlet in the circuit be faulty? Or none of the above. I like to resolve it without hiring an electrician. Thanks for any help/tips you have.

I upgrading the electrical in my parents home and need to replace the old fuse boxes with a subpanel. The house was remodeled in the 60's and a 200amp service installed. The old service bacame a subpanel with an assortment of small fuse boxes hanging off it. I am replacing that mess with a new subpanel. My questions concern wiring between the main panel and new sub. Currently there are three wires feeding the subpanel (2 hot, 1 neutral). Question #1: Do I need to add a ground wire to link the ground buses on the main and subpanels? If so is that the only grounding point for the subpanel? I know that the neutral and ground busses cannot be linked in the subpanel. Question #2: Is it permissible to have a splice in the circuit feeding the stove or other major appliance? I would like to run new wire from the subpanel to the old subpanel and use it as a splice box.
