Is there a fitting that allows me to run a new conduit into an existing conduit run? Without re-pulling the existing wires, so i wouldn't want to cut the conduit.
My idea would be to somehow replace the cover off an existing LB and add some special "box" there........
short version. no.
how to do it? GRC or EMT?
GRC:
get a C, a T or an X, two 6" nipples, and an ericcson.
however, is it an LB, an LR, or an LL?
you are gonna cut the pipe on one side of the existing
and inadequate condulet, spin on a new one, put the
two 6" nipples with an ericcson in between them next,
then a c condulet, make it all up, and then put wire in
between the two condulets, and make it up.
you may** have issues with wire count doubling in the
condulet, and exceeding the volume.
** who are we kidding? you will have issues with fill.
but, short of repulling the wire, there is no simple solution.
gets done a lot in refineries.
