I have an outdoor porch light that when I took off today had two black wires twisted together and two white wires twisted together and they were connected to the house wires one black and one white, the bare wire which I assume is a ground wire was not being used. this fixture has worked great for years just wanted a newer one. The new light fixture has one white and one black wire and also a yellow/green wire which I hooked up to the bare wire coming out of the house. When I turned it on it worked then tripped the breaker. What did I do wrong?

Just installed new wiring in my garage (now covered with

Just installed new wiring in my garage (now covered with insulation and plywood). 7 of 8 circuits working just fine. The last one (of course it's the last one) shoots a spark and flips off instantly when I try to turn the breaker on. There is only one outlet on this circuit. I've checked the wiring in the outlet box and in the panel box, I've tried an alternate breaker and outlet. No luck. Leaves me thinking the only other issue is the wire - and that I must have hit the wire with a nail when installing plywood. Would that cause this issue?I'm not sure of how to test for a "hot" nail since I can't even get the breaker to stay on momentarily. Any thoughts?

Follow up-there are 4 wires that were connected to switch incorrectly. One hot black wire and one red, one black, one black/white. These last three are not live with power on. The two switches should turn on/off the fan and the light independently(the switch is two toggle switches) , the other should be always on to power the circuit that controls the outlet and light that are connected. What are the connections?

I have aswitches light. The light fixture is simple 1 bulb.

I have a*****switches for 1 light. The light fixture is simple 1 bulb. The wires are white, black, copper ground. In that junction box, there is 2 sets of romex coming in that each have copper ground, black, white and red. The red are connected and have a wire nut. The problem is this: the wiring for the previous light fixture, same black, white, copper ground were all undone from the romex and both sets undone except ground and reds. Cannot figure it proper to wire it right without tripping breaker. Somehow did i cause 110 to become 220? If so, what is the proper configuration so this doesny happen??

Certain circuits in my house will go out. Other parts of the

Certain circuits in my house will go out. Other parts of the house will work. None of the inside breakers are tripped. This has been happening on and off for a while with slightly different outcomes. The latest example was, last night, there were three or four circuits not working which included lights in my bath, the washing machine and lights in the living room. I went to the kitchen and the stove clock was on so I assumed that circuit was working. I turned on the stove itself (as if to cook something) and the non working circuits came back on line. I had checked the breaker box prior to turning on the stove and none of the breakers were tripped. I did flip the breakers anyway but that did not help. Only turning on the stove helped. Could it be the breaker panel itself? It does not appear to be too dated. Also, sometimes previously, the main breaker outside would trip but that has not happened in a while.
