LB Fitting underground???????


I'm in Ontario. I have to run wire from the hydro meter outside the garage under concrete floor into the service panel in the mechanical room. In order to get the line low enouch to be under the concrete as required by code the LB fitting outside ends up below grade. What can I do? Is there a different fitting that can be below grade or can I cover the LB fitting in concrete before it enters the house?
Please help asap.

I am sure the CEC would require the LB cover to be accessible after installation the same as the NEC. Can you use a 90 degree elbow?

Why would you want to encase a fitting that is made to be accessible? No way is it listed for that use.

You can't use an LB underground. Use long sweep elbow to allow the cables to be pulled.

I would like to but the 90 degree elbow brings it too far out from the wall so how do I get the vertical pipe against the wall to meet the hydro meter.

I don't want to encase it I'm trying to get the line from coming out of the foundation wall below grade up to the hydro meter.

Right now it's just a 4 ought (sp?) 3 wire coming out of a 2" PVC pipe coming out of the foundation wall. There is no basement, it's a slab on grade construction so all plumbing and the service cable is underground.

can you make a sketch? you say it is slab on grade but then mention a foundation. is the 2" conduit coming out of the footing? or better yet, does that 2" conduit come out above or below grade?

You can't bury an LB. You have two choices, raise the point of entry above grade or dig a hole and leave the LB exposed as if it was a basement window below grade.
