im trying to add a receptacle to my kitchen island. i want to run the wiring under the cement. what other step i need to do like what do i need to use to cut that cement how can i pull that cement i cut up please help me thanks
Brad is correct about PT reinforced cement. But, since you do not already have a receptacle serving the island (required in newer homes), I am going to guess that the home is older and less likely to have this issue. Although you should try to find out for sure, if possible. PT reinforcing is fairly common in apartment/condo buildings, but is rare for a single family residence in my area (WA State). May be different where you are though. When you install this, use conduit for this. Do not use direct buried wire. First, it cannot be in poured cement without protection at the entry and exit points (must be poured under the cement and be protected). Second, if there were any failures (or if you needed to add circuits) later, you will not be happy tearing up the floor again. Insist on at least a 3/4 conduit (1 inch might be better yet). This would allow for an additional circuit or two later. If you are going to rip into the cement floor, do it right the first time.
I would have to say your probably choosing the hardest way to do this, If your house is new it could be post tension, don't cut this, cables under high tension! might be easier to go through walls and do a little drywall repair.but if you insist on concrete cutting, wet saw at rental yard lots of water and mess, jack hammer to break and remove concrete. Have fun. Don't forget to protect the receptacle with a Ground fault circuit interrupter, required in kitchens, National Electric Code
I agree with both your answers so far! But what about coming down from the ceiling? Are there cabinets above this island? Could you install decorative posts down to the island and then possibly install your receptacle in that?
