[RE-wrenches] Replacing grounded inverters

[Jerry Shafer]

In most cases the modules have the thick double insulated whips, now with
some of the older trinas we replaced the whips as they as field
serviceable, as I recall the sharps have not been a problem. there can be
an issue when we get to the old Jbox hard wire systems
