All my electrical lines are EMT conduits in the attic. There is a
perfect
spot in my bathroom I would like to install an exhaust fan but the 1/2"
conduit is in the way. It is 4" above the ceiling board and I need 8" of
clearance to fit that fan. I have considered all other spots and this is
the only logical spot for a variety of reasons.

Is there a way I can reroute this conduit "locally"?

What I mean is I have no idea where it goes and where it is coming from,
it
is in a tight spot in the attic and I can see as far as I can see with a
flash light and not sure where this conduit is going each way.

Can I cut the pipe where I would want the exhaust fan, and put in four
90
degree elbows to "offset" the pipe around the fan? If so, how would I do
that?

I cannot think of a way to do this without having to insert two junction
boxes at the two cut ends. Is that the only way?

Thanks,

Unless you're willing to remove & re-pull some wire.....the two
junction boxes is the only way I can see to do it.

If you do decide remove & re-pull, you'll have to find the boxes where
the run starts & ends. When you pull out the conductors, tie a 1/8"
nylon cord to wire so you don't have to run a fish fresh.

To accomplish your offset I would suggest making a multiple bend
offset segment at you can place in the conduit run using only two
couplers.

Of course you'll have to cut the cord to insert the offset and knot
the cord back together. You'll also have to buy replacement wire
since the run is now longer.

It all depends on whether you are ok with junction boxes in the attic.

I agree, and the OP dont want to have to fish a wire thru FOUR 90deg.
bends. In fact I question if this many bends are allowed by code????

At the same time, if the OP cant find where this conduit begins and
ends, I question whether he is capable of doing this job. How hard is
it to follow a piece of pipe? Now, if this conduit goes under a floor
or some other obstacles, then I might understand the problem, but if
this is the case, how can the wires be re-run without ripping
something apart..... I think I'd offset that fan by the 6 or 8 inches
to avoid the pipe. Of course that fan will need a power source too,
and that means somewhere there will need to be a source of power.

I don't mean I can't find where the conduit begins and ends. What I mean is
I don't want to bother with it because it runs at least twenty feet in each
direction and I am not sure where it ends. In any event I don't want to
reroute over fifty feet or more of wiring to side step a fan, It is at the
tight end of an A-frame roof so space is tight.

As far as offseting the fan that is a problem like I said there are a
variety of reasons I cannot do that due to other obstructions.

Power source for the fan is already taken care of via a different junction
box.
