Well, it sounds like most are leaning towards the Progressive Dynamics. Is the install of the PD very simple? I am certainly not an electrician and when taking the old unit out, took good notes and it was a simple uninstall but was planning on putting back in the same unit to simplify the reinstall.
It has been a while since I looked at my notes, but as I recall, all I had was a black and white coming down from panel. I had to disconnect a white from the back of the bank and a black from a ground. Any corrections and assistance on what it takes to reinstall the PD?
