a neighbor of mine, has a shed that is powered by a extension cord (about

legal, he asked me how to correct it and I told to run uf-b wire under ground
next to the fence. He asked me if he could put plugs on the end of the uf-b. I
told him I did not know ? does any one know if the current way is legal? ,and
if not what is the easiest way to fix?

You told him something is not legal, then you ask what is legal? Got
it. Try the alt.home.repair group on Usenet.
