Building a kitchen island. Running electrical conduit.

Hello. I am making a kitchen island and preparing electrical conduit before I lay down new flooring. I cut a groove for the conduit in slab already for the conduit.
The 90 degree PVC elbow has a big radius and its impossible to make it touching the cabinets back wall. It would have to stick out inside the cabinets.

I know that the electrical wire cannot be bent much but we were allowed to use short 90 degree elbows like the one attached below, I was not able to find them anywhere in US.



This is how it looks and how I am planning to do it, but I would want to make it as close as possible to the back cabinet wall.

What is the best and proper way of doing this?

Not supposed to use a close elbow as makes it too hard to pull wire through.

Not sure what you are trying to do. Can you cut a deeper channel in the concrete? Otherwise strategic placement of the cabinets with cutting a small notch. The curve is below the bottom shelf so isn't seen.

You cannot use that 90. It is not for electrical installation. You need to make a deeper trench.

I would Install a 4x4x1 1/2" metal box in the bottom of the cabinet and run cables or convert the PVC conduit to a flexible conduit (FMC, NFMC, Etc). Just make sure not to exceed 360 degrees of bends between pull points.

Agree! You cannot use a plumbing elbow with conduit.

Use a shallow angle to bring the 90 up close.to the cabinet instead of at a 90 to the cabinet.

You could use a conduit body: https://www.homedepot.com/b/Electric...z0usncZ1z10wqp

A Type LB on end with the back opening attached to the conduit in the groove and the end opening up into the cabinet.

A Type LL or LR in the groove (cover on top) with a conduit ell on the side opening against the cabinet would also work.

In either case the cover does not have to be accessible after the wires are installed as long as there are no splices or connections inside the fitting.

Not true. It does have to remain accessible.

Joed is correct. Conduit bodies are required to be installed following the same rules as junction boxes, splices or not.

Hi, what size conduit are you running ? This should do what you are trying to do.
