230v SJO = historically significant

[wyreman]

So I have to install a lighted mirror vanity in an impossibly tight, historically significant wall
There is very little clearance to make a radius bend w mc cable
The entire area is hard and rigid.
If we were in Germany, you could really run the equivalent of SJO cord to the mirror with 230v!

So what kind of conductor material will have flexibility to make that very tight radius bend without jackhammering out the antique tile?
How about a low voltage system - retro fit some led driver into that vanity bar and run the source in LV cabling?

The wall in question is solid concrete
that has been firred out the depth of a mirror long ago.

The surface is:
small gap, fir, stucco, marble, View attachment 12375
and another layer of stucco and tile!

Is there any material I can use w 110v that will have a tight radius in this four story residence? thx

Does the construction of the lighted mirror interfere with a right angle MC connector?

the core hole for the power inlet is like an inch diameter maybe 3/4 and the thickness of the wall is almost 2 or 3 inches i reckon it to be
its got to be a straight connector given the core hole

It's like you have to wire up two whips w straight connectors and then
have someone reeling them in as you push the mirror to the wall
to pickup the slack

I still believe you could pull them straight down to a big jbox - but the under-sink is going to have a "very special" tile treatment
so that avenue is closed.

I originally had planned to surface raceway to a box with
enough depth to mount to the back concrete wall and still have the box stick out a couple of inches to receive the wire mold.

Then I would punch a couple holes in the top of the 8x8x8 box closest to the concrete wall . then
mount the mirror with the whips while i
have someone pull the mc whips straight down as i brought the mirror to the wall.

Or I could kind of do something similar from the top, extending from the jbox that has a useful conduit in there.

It keeps coming down to
very hard materials, close tolerances and the tightness of the mc bending radius.

Don't they sell some kind of armored SO cord for use in robots or something??? =0
I remember using a very small -like 3/8" - liquidtight cable assembly that was populated with 3 #12's, a special material used in skyscraper concrete i think it was

I think i will have to reinvent that mirror as a LED lighted mirror, find someplace to mount a dc xfmr and wire that thing with some landscaper's cable!

I think the MC could make the bend. Are you saying you have to make up the wires inside the fixture before sliding the mirror into place?

I might be able to have it just poking out and make it up in position. I'll try tomrw.
Maybe it's easier than it looks.
I was just over scheduled.
I'll just put my hand on it tomorrow and push.
It'll probably be fine. thx Dave!

Arlington makes a new MC connector that you can pop on from inside the box. That could make things easier.

Yep, just started using them in some remodels.
