In order to install Wiremold metal raceway on the inside garage wall for
120v wiring for the exterior lights I need to cross an existing run of
Wiremold that carries the 24v wiring for the sprinkler system.

Would it be kosher to have the new Wiremold simply cross over the top of
the existing Wiremold and thus not be flat against the wall for the whole
of its length? Or lift the existing Wiremold away from the wall and let
the new Wiremold pass under it and thus remain flat against the wall?
Or...?


*It is possible to bend a saddle in Wiremold, but it is a little tricky.
The Wiremold tends to get distorted as it is bent. You cannot have the
raceway float. You could put some blocks under it at intervals and strap it
on to them. I seem to recall Wiremold making a flexible joint which would
work in your case. Check their catalog.
