Do you really need the fourth wire if there is a ground / case lug on
the back of the amp tied to your station ground ? W4DNR

This thread has induced me to do what I have been meaning to do for
ages. I have an old PT3000 (yes, that is the correct number) amp which
has ground and neutral tied together internally as well as a few 120V
components. So a four wire connection seems to be the safest solution.
Plug and receptacle easy - 20A twistlock. (Don't think 15A is
available.)
Cable not so easy. All I can easily get here is SOOW which in 12/4 is
about the thickness of an elephant's trunk. I can order SJOOW which is
better but still pretty thick. Both those cables are intended for
industrial use. I can't find any consumer type indoor cable. Does such
an animal exist?
