OK, continuation question. The updating the outlets went great so I am going to continue. I have another outlet on my ceiling that the garage door opener plugs into. The previous owner plugged in an extension cord to the other outlet and then ran it across the ceiling before cutting the end off and pushing it through a hole in the side of the house which he wired in to an outdoor security light. I would like to fix this and I am thinking I will take the same conduit style approach. However, there are some different parameters.

I am going to mount a plastic outdoor box to the siding of the house on to which I will attach the light fixture. Can I attach emt conduit to a pvc box as this? My plan had been to thread a set screw type 1/2 emt fitting into the box, then to penetrate into the garage with the emt before fitting a 90 degree bend fixture, and running the emt up to the ceiling and then over to the junction box. Is this ok?

Second, the junction box that is there presently is a plastic 1 gang box. Previously I had used box extenders to allow me to attach conduit to my existing boxes. I cannot seem to find a 1 gang pvc extension that is tapped to take conduit. Can I extend this pvc box using a standard metal box extension or must I find a pvc box?

Thanks,
Brian

The box that you had a picture of is made as an extension also. Look for one with the back cut out.
Is Romex allowed in your area?

I would run the conduit from the receptacle to a j box, and from the j box use romex to feed the outside light.
You need a switch for this light also.

Hi JBfan, Sorry, the pictures i posted previously were from a seperate task that was completed as discussed earlier in the thread. I did get an extension for that octagon box and everything worked out great. I am now taking on a second project that involves adding conduit and extending an outlet that is presently housed in a 1 gang plastic box. What I cant seem to find is a 1 gang plastic extension that will take conduit. So I was wondering is it possible to extend my 1 gang plastic box with a metal box extension?

Thanks!
Brian

he's refering to the picture i posted...they make an extension box for utility boxes too which would extend your plug box out for you.
