In my area Habitat doesn't allow volunteers to do any electrical work. They used to, but there were a lot of problems afterward. I know this because when I was preparing to start my company, I attempted to volunteer so I could get some experience doing residential wiring. I had only done commercial and industrial electrical work up until then. So I ended up doing a lot of framing instead. The foreman gave me a nail gun to use since I was the only volunteer who actually had any construction experience. Everyone else got a hammer.we do a lot of Habitat houses and there can be several "volunteers".
I only use a hammer / stick in new construction. Remodels get the rotary laser......for countertops, I chalked a line and set them all the same height.
nothing worse than a homeowner mad about an outlet 1/4” off with a tile backsplash. Grout lines will definitely show it.
I don't own a rotary laser but I think his point was to do something to ensure they are same "level" and that is what I ordinarily will do for countertop outlets as well.I only use a hammer / stick in new construction. Remodels get the rotary laser.
If you base a chalkline based on an unlevel floor, you'll have unlevel boxes above the counter. A good trim carpenter will shim the cabinets to make the c'top perfect, and you'll end up with unlevel devices on a perfect tile backsplash.
He said he chalk lines at the same height. If the floor's out-of-level then the chalk line's out-of-level.I don't own a rotary laser but I think his point was to do something to ensure they are same "level" and that is what I ordinarily will do for countertop outlets as well.
I've never seen a plastic box for residential with a center line to go by if you place/measure to the center of a box. You could figure out one then cut a gauge stick for the rest.Residential 16" , commercial 18" to center.
Ruler or jig for height and depth.
Space to code plus whatever floats mine or the customers boat.
Where it matters I use a level.
RFI it. I doubt the tilesetter is going to tell anyone "Put the top/bottom of the box at xx inches". They'll need to know where the top of the backsplash is. That's based on how thing the countertop is. And it's all setting on a cabinet that who knows how much is going to be shimmed up.Tell the GC you will not be responsible for outlet placement without that input.
