THanks Southwire is the name on the box
For the "Attached cord crowd how to "install" the easy way
you will need
A hacksaw
Two 50 amp plugs
Two 50 amp outlets (Or if your RV is 30 amp make that 2 pair 30 amp)
These can be RV type or Twist lock.
Find space or the unit behind the breaker box.
Using hack saw cut the cord leaving enough attached to the breaker box that you can work with it.
Install a 50 amp MALE plug on this
Pull the cord out (or in) and whck off a section.
For southwire TRC surge guards wack of 2 sertions about 10"
For Progressive Industires HW-50C I'm not sure The following will be or the TRC product
To one length attach an matching the plug 50 amp outlet (Female)
Attach the other end of this wire to the Surge Guard Load side (output)
Tape over the terminals to protect from accidential contact.
To the other segement put the plug and hook to the INPUT (Line) end of the surge guard
TRape over those contacts as well
Put the remaining outlet on the cut end of the shore cord
Plug in
Plug in Reote and enjoy
I'm not sure if the Progressive needs two short sections like the TRC
or one longer one with some special attengion to how the wires are connected
But the connections are, as I recall, inside the box (Do not have one just read the instructions)
