Hello:

Regarding those Bell electrical outdoor junction boxes:

Want to put up an outdoor light on the outside of the house.

NM wire would be coming thru house siding into one of these junction
boxes.

The part of the box that will be laying against the siding has a threaded
hole
for the wire (or some other fitting) to go thru.

It's a pretty rough thread.

Questions:

a. Is it Code required that the NM wire from the house side be clamped
where it enters this type of box ?

Yes


b. If so, should I use one of those NM wire fittings that one uses with
the
regular indoor metal junction boxes that clamps the wire, as well as
providing a threaded section on the other end ?

Yes a romex connector or sometimes called a two screw connector will thread
into the hole


c. Or, just lead the NM into the box and live with it brushing against
the
internal threaded hole of the box ?
(do they make a bushing for this purpose; couldn't find anything
appropriate at HD ?)





B.
