At around 1 a.m. this morning a ceiling light switched on of

At around 1 a.m. this morning a ceiling light switched on of its own accord seemingly at the same instant that the 'house vent circulating system" shut down. Is this the effect of a power surge or what?

I plugged a TV into a grounded 3 prong outlet, then when I attempted to connect the coaxial cable it sparked (enough to burn the cable connector). This is in an area of newer electrical work in an older home. Testing with a multimeter shows 117v across terminals, 117v from short slot (black) to ground, and 0 from long slot (white) to ground. Noncontact tester lights up anywhere near the plug. Other plugs in the same circuit test same way. Connecting the same TV and coaxial to an outlet on a different circuit (via extension cord) gave no problems. Connecting a TV with 2 prong plug to same outlet and coax also gave no problems. I am in the construction business and relatively competent in electrical but I can't find a source for this problem.

This house has a 200amp panel, the service entrance cable

This house has a 200amp panel, the service entrance cable comes from underground to the meter. The homeowner asked me if he could install a junction box in the SEC between the meter and the house panel. He has a barn he just built and wants to install a 200amp three phase panel and power it from the junction box he would have installed between the SEC and house panel. I told him that may be overloading your SEC which I have not checked yet to see what size the cable is yet, and is it even possible to splice power feeding three phase off of a SEC. He is trying to avoid the sub panel drawing out of his house panel. If this don't make sense I will try to rephrase the questions

I have recently been installing motion and humidity sensing

Hi, I have recently been installing motion and humidity sensing switches to my bathrooms.The first was easy enough, opened the gang box and there were 3 bundles of 3 wires each. The 2 switches which previously controlled the fan and light independently were easily replaced. All done, no surprises.I open the second box in a different bathroom and there are 4 bundles of 3 wires for the same 2 switches.I have connected the new switch and bundled all 4 neutrals and all grounds. I am now left with one ( non hot) black.I am at a loss as to where to put this.I have as a result lost several lights in an adjacent room which is connected to the same fuse at the junction box.Please are you able to help me?

I have a rental townhome and both bathroom (stacked on top

i have a rental townhome and both bathroom (stacked on top of each other) lights and fans are out. They both have GFI receptacles. The circuit panel is not marked very well but I found a 15 amp circuit breaker in the panel that was bad so I thought that was it. I replaced the circuit breaker and now all breakers are showing voltage (using a tester) Now I'm not sure what the problem might be. Can one bad GFI receptacle cause the whole circuit to fault. Any ideas?
