I'm renovating a kitchen and other parts of a house and my electrician (who is a licensed master electrician but is apparently clueless when something gets away from codes and "normal" work for electricians, I'll explain more about that later) ran a bunch of new wiring for the range (gas range but just a regular outlet for the clock and stuff) the dishwasher, garbage disposal and over the range microwave and had them ending at the new boxes in the existing walls. We had changed pretty much the whole layout for the kitchen, so that's way we needed new spots for all of these outlets. Then I had some drywallers who had worked on another project for me and did a great job come in and we decided to just go right over the old drywall, its a 1950's house and the walls were rather beat up plus we had to tear into them all over the place for the new wiring, some new plumbing, etc. so these guys agreed it would take forever to attempt to patch all the various holes and still might not look right. Looking back, we could've just demo'd all the existing drywall but these guys had been doing drywall for years and said lets just go over the old stuff. They did a good job with the drywall work, they'd done it before and just plotted out where the studs were and put up the new stuff in record time but they somehow managed to cover all these outlet boxes! It blows my mind but they did it! Now, my electrician, who's just starting out on his own and is a licensed master electrician (you can't pull permits here if you're not and he's pulled permits on several places for me now) is perplexed as to how he's going to figure out where these boxes are exactly without just starting to cut away and look for them! He told me that on the phone this afternoon while I was somewhere else. I thought about it for a bit and called him back and said, don't they make the stud sensors that also alert you to live wiring inside of walls? He apparently hadn't thought of that but I know they do and I'm wondering if there are any other devices made for this purpose of if I'm fine with just one of these stud sensors that alerts to live wiring? I'm meeting him there tomorrow to figure this all out so I need any advice soon. For anyone wondering how in the world I was able to find a master electrician who didn't know this stuff, I've ran into a couple of issues like this with him, he's done a few projects for me. He did his education and on the job training like they all have to for however many years and just struck out on his own now. If its anything to do with codes and what size wire you need for whatever and how many feet from something you need an outlet, etc all that stuff he knows 100%, but when you throw something like this that's maybe not in the textbook, like what do you do when the drywall guy buries your boxes, things seem to get murky fast! So, I'm just wondering should I just get one of those stud sensors or is there another device that would be easier or more accurate for this? Thanks!

Hey all. Need a bit of advice. I have a home built in 1927 that is a mix of Knob and tube and romex. I'd like to do a new run of conduit from the panel in the garage up to the front room. Over the years, a few people got lazy and just put in floor receptacle directly through the floor. I'd like to put a receptacle in the wall and curious what the best way to do this is since there is no craw space access. My thought was to terminate the run with a metal box as close as I can get to the outlet, then have romex out of the box through the floor and into the wall which would feed into a plastic receptacle. I know that you should never use MC or BX with plastic, but does this setup sound safe? I've never had a setup where the there is no subfloor and the wood floor is visible from the garage, so sorry if this question is naive. Quick sketch if none of that makes sense: [ATTACH]33727[/ATTACH] Thanks
