I'd like to pour a concrete slab in my backyard for my bbq. I'd like to have power available there. The simplest solution would be to run UF-B to the slab, bring it up through the slab in a conduit, and stick a weatherproof outlet box on the conduit 2" or so above the slab surface.

This is what I would like to do, knowing that when the grill is in place it will be a physical barrier to tripping over the outlet, but I'm not too sure that this arrangement would sit well with the Powers That Be. Without a grill present, this could be a tripping hazard and I don't know what the rules and regs are about something like that.

What's the simplest way to install an outlet on a concrete slab I'm about to pour?

 

Not sure if it is allowed, but if it is, I would for sure use RMT (heavy pipe) type conduit, not EMT or PVC.

 

Best to have a short wall or something else solid to mount the box to. Otherwise you need two threaded conduits to support a box.

Darn, what a price premium over supply house prices for the Garden post.

 

I would do a stainless unistrut with pvc conduit.

 

They are not cheap.

Although it's a great idea Marq..... an outside floor pocket would be a headache forever.

A weatherproof box on a short stub of 3/4" galvanized pipe would work fine.
The galvanized pipe is just a sleeve for the UF cable.

 

I've also seen posts (treated wood or even a capped aluminum post) put into the ground for the conduit to strap to. It's a little more durable that way if it gets bumped.

 

I don't disagree, was kind of surprised to find one.

I would try to incorporate something in a vertical wall, something part of the patio/deck!

 

Hi, this could be an option, bury it so that the opening is below the slab for access latter, also if you use the conduit route I would use 2 conduit stubs , 1 for support and and to keep it from turning the other for the cable.
sorry I copy the link , I’ll something else.

Remember that the UF-B cable cannot enter the slab without being in conduit.

 

Stainless strut might be hard to find without ordering a 10 foot stick. Galvanized strut would be fine.
