I just bought a new exhaust fan for my bathroom to replace the 747 that
currently resides there. The problem is that on the old fan housing, the
electrical and exhaust were on the same side. On the new fan, they're on
Given that it's a 1st floor bathroom with no access from above, what's the
best way to tackle this? The romex is stapled to the joist, so there's no
give in it. Is it legal to extend the wiring and bury a junction box in the
ceiling? There's little room to extend the exhaust ducts to the opposite
side of the fan.
junction boxes must be accessible with out removing finishes.
get a fan that will fit the housing that does not make as much noise. Lots
of luck if it is older. The fan manufactures seem to change designs like the
car manufactures. Well not every year but almost.
The romex should be stapled near the fan but should still have a loose loop
farther back that you can pull in, according to most codes,..... but it's
not always that way in the real world.
While not generally done......
If you are good with soldering, you "can" splice on a new piece using
ROSIN CORE/ELECTRICAL solder.
Tape or use shrink wrap on each conductor, then tape the whole mess
This is a fix that meets code in most areas, but is a fix of last resort.
If in doubt, best to just find a fan housing that has the wiring in the
right spot for your needs
All of the jurisdictions I work in expressly prohibit soldering
connections/splices now. A splice is a splice no matter the method of
connection. Splices are required to be in a junction box and that box must
You can't bury a box in a place that you have to disturb the building
finish to get at it but removing the fan is not disturbing the finish.
If all the box serves is the fan this is no different than the box
above a can light.
