I was wondering if someone would know this. I have AL wiring in the
house. I'm renovating whole house and was thinking of replacing old
wiring. I'm not planing on removing the walls, but will be able to
open up the floors. I have good access from the attic. Currently other
than the light fixtures there is absolutely no junction boxes in the
attic. All the outlets are wires in series.
Here is the question. Is it against the code (Ontario, Canada) to put
junction boxes and wire the outlets directly from the junction boxes
( I suppose I could manage to wire two outlets per junction box), or
should I follow the current design.
House was wired in late 60's.

Thanks for all your help.

Don't follow the description clearly -- what happens to the existing
outlet(s)/wire?

In general, I don't think there's an proscription against using the
junction box as long as they are acessible, but as noted, don't follow
the plan well enough as described to see what you're actually driving
at so no detailed thoughts beyond that at the moment...

Thanks for the reply. Sorry for not being clear on my plans. Basically
I want to rewire existing outlets with new cable (14-2), by pulling
out the old AL wire. I will use the existing wire to fish the new one
in place and use junction boxes to connect the outlets. At the same
time I would like to put ceiling light fixtures and wire them to the
existing switches that were connected to one of the outlets.

Hope this time I was more clear on what I wanted to do.

Dom

Unless something unique in CN code, don't see any problem again as
long as the junction boxes are acessible. What you may run into is a
problem in getting the old wire out w/o tearing up the wall as they
may well have stapled it to joists tightly enough you'll not pull it.
If, of course, you can, there's no reason you can't pull up and
through the attic from one receptacle to the next where you don't need
a junction box for some other purpose. You would start the feed by
pulling the old with a string attached, of course, then feed from one
end and use the fish again at the other to pull back down. Assuming
open wall cavities (no infill insulation, blocking, plumbing, etc.,
etc.) you could probably pull two 14's together. OTOH, in the big
scheme of things if you're doing significant remodeling, repairing a
few holes in the walls may be simpler overall.

This won't work. The wire will be stapled to the studs and will not
really pull out that easy. You certainly will not be pulling the new
wire in that way. This is going to be a bigger job that you planned.
The first thing you need to find out is if the stud bays have "fire
stops" in them. (2x4s across the bay 4' up) That will really frustrate
your wire pulling unless you can come up from the bottom.
They do make a "diversibit" that is 5' long to drill these from the
top but be careful you don't miss and come out the drywall.
Then fish down with a short piece of chain in the string so you can
catch it with a retriever magnet through the hole in the box.
It is as hard as it sounds.
