With 32 years doing electrical maintenance at a power plant over the years I have become a little OCD. when it comes to things electrical.Now when it comes to a lot of things the old rule if it aint broke then don't fix it.Now my old rule is if you haven't checked it out then you can't trust it.So with that said I figured I would do some recon on the main electrical panel and I was surprised how many loose connections their were.The main shore power feed was loose enough to harden the insulation heat on the wire and required it to be trimmed back and a new connector installed. One less thing to worry about.
