Kudos to Progressive Dynamics
I have an external PT-50C. Noticed some dark coating on one of prongs of my 50amp cord. Looking at the PT-50C I saw that the corresponding insert was charred/melted and the contacts had a large gap.
Unit is 3 years old and I treat it gently but something must have caused some arcing.
Progressive has a GREAT replacement program. Send the old one back with a check for $89.95. Get a reconditioned unit in return. And the re-con that I got is the latest style and now includes a weather cover over the plug in point to give additional weather sealing where your cord plugs in.
Sent UPS ground and arrived at Progressive on Monday 12/19. I received the reconditioned unit today 12/23.
