I am running two 2-wire and one 3-wire Romex cables from the panel in the basement to another part of the basement. For most of the run I have access to the ceiling joists, but I need to cross a 2.5 meter section which is closed off and contains lots of ducts and pipes.

Here's the obstruction. I am thinking of fishing cable between the joists on the top right of the picture:

And a look inside the space: enter image description here

This means that I can't support the cable every 1.5 meters, but Rule 12-520 in CEC says:

Where the cable is used in concealed wiring and it is impracticable to 
provide the supports required by Rule 12-510, and where metal sheeting 
or cladding, metal joists, metal top or bottom plates, or metal studs 
are not used, the cable shall be permitted to be fished.

So I just want to make sure that I understood this correctly. Can I fish the cable through, despite the fact that there are some metal ducts in the space?

  • I just marked your earlier question - which is the same question - a duplicate of this one. Normally it would be done the other way 'round. For reference in the future, please edit your original question to add detail, don't re-ask and make us all work at the problem again (we won't, because, we have memories). Editing a question bumps it to the top. – Harper - Reinstate Monica Nov 8 '18 at 20:34
  • @Harper Thanks, I'll keep this in mind. I wasn't sure what to do, b/c my previous question was too broad, whereas this one asks a more direct and specific question. – Val Blant Nov 8 '18 at 22:26
