Is it OK/orthodox to chissel out a trench about 1 1/2" deep into concrete slab , and lay a coduit , then slide the 220 wire through it? Its for a new kitchen, with island in the middle of room, and cooktop is on island. Someone told me its not code.

How else do they get islands with cooktops?? (We are renovating old kitchen to new. current stove is against wall, which will be yanked, opening up the room)

Thanks

Slab home, you are going to have to go deeper. Now of course, they make systems, to allow you do do what you want to do, but it has to be done correctly. Now if this is a condo on a pre-stressed slab, you cannot make any cuts into the floor.

 

[noquacks]

Thanks. No condo- single home. So, it can be done, and be Kosher?

If it is a slab on grade, you will have to cut through the concrete and install conduit under the slab. Then patch with concrete. Run UF, or individual THWN conductors with approved fittings and enclosures.

Nope, If the new construction plans had called for an island cooking station they would have positioned a conduit stub up at the island site. Unfortunately you sound like this is a remodel or complete change of kitchen location. You will have to cut the concrete as electures mentioned and for what it is worth it isn't generally all that hard to do with the right equipment. IMO it would be a lot easier than chiseling a channel.....:thumbsup:

While you have the slab opened, you'll need to run two conduits.
1) for the cooktop
2) for the island receptacles

thanks, stub. geez- all that concrete dust......no way. looks like im gonna drop it down, and hide in a thin column. kinda like a small wall. oh well, wont look as nice but not gonna cut/chisel into 4" concrete.
Thnaks,people

There is always a wet saw and a shop vac. You will have very little dust if any at all.

Too much, roll!! Are you surre? What kind of wet saw, as only kinds Ive seen so far are the ones for ceramic tile......

It's way easier to cut through the slab than to make a channel in it. Hire a concrete cutting company - that's what they do! They'll use a hydraulic wet saw and clean up the mess.

 

[rrolleston]

You may be able to find a place where you can rent one but only do this if you feel comfortable doing it because they are not an easy tool to operate.

I like mpoulton's suggestion.

Where I work we use a gas powered demolition wet saw. But the one we use is about $1500

Nope ... one conduit.

My last wet saw job was a lot more complicated and cost me $300. Well well worth it. And, yes, all the THWN can go in one conduit. With some ingenuity I think you may be able to just run one ground, sized of course for the largest amperage.

I hate slabs

 

[noquacks]

Wow- so much good info! Now, I got the idea.

 

[md2lgyk]

You'd better be really careful. I don't know how it's done today, but the only slab house I ever owned (built in 1948) had the plumbing actually IN the slab rather than underneath it.

Good point but it seems like the saw company might have a way to locate embedded pipes. At least if they're metal, if they're PVC.....?

Going to need to do something if you want the island. The code does require receptacles on the island.
