Today we got some serious thunder and lightning in Boston area. At one point during the day there was a huge boom and it sounded like a lightning bolt hit our house. The power didn't go off but my wife and I smelt a burning smell. Also, my router and another piece of equipment were fried (even though plugged into a power surge protector). Now I have one fuse in my house which controls some lights in my living room that will not stop tripping. Someone told me to unplug everything in the room and to reset fuse, but still not helping. And the even weirder thing is that I just noticed that there is black residue in several toilets in the house. See picture attached. I'm stumped. Any ideas?

Hi We had a leak at home which destroyed our floors and kitchen. We are now trying to lay out a new kitchen. Previously we had a range with an electric oven and a gas cooktop. The oven was fed from a 240V socket. I believe the breaker is a 40A For the refit we want a built-in double electric oven, roughly where the range was. But we want an induction cooktop on the other side of the (small) kitchen). We had induction back in the UK and it was awesome. The kitchen planner has overlooked the fact there is no 240V socket on that side. The hobs can pull 8kW, so we're talking over 30A max for that appliance. Providing the breaker and cables can take the current of both cooktop AND oven, can we channel the concrete and lay conduit under the kitchen floor to add the cooktop socket in parallel with the oven? The concrete is not pre-stressed etc, just regular slab pour. Thanks
