I didn't want to Hi-jack Roguewave's post on replacing 30A cord ends so started this thread.
My question... and I'm here to learn - not trying to convince anyone one way or another
I've dissected / autopsied several 30A plugs but have never done a 50A and I've read & reread RC's comparison at Compass Marine How To on Shore Power Cords
I've read here on TF that the over heat / meltdown problems etc experienced w/ 30A Twist-Lock cord ends shouldn't be extended to 50A Twist-Lock ends as they "are more robust"
or that the (purported) advantages of of Smart Plug apply to 30A NOT 50A cords / ends
What makes the design of a 50A Twist-lock that much better than the design of the 30A?
Why do advantages of of Smart Plug apply to 30A NOT 50A cords / ends
I get that the blades may be thicker, etc but isn't the reduced contact area - due to the need to twist the plug to lock it - similar for both?
My marina / dock supplies 50A/125V and my boat has 2 X 30A/125V inlets.
I use a 50A/30A 125V splitter and 2 30A power cords. Can't change anything on shore but I am considering changing to 30A Smart Plugs & Boat Inlet in the future - I believe there is a benefit and willing to pay a premium - when I need to change plugs / inlets but so far cord ends are good and no overheating. I am aware of the issue and check often - also I'm in a relatively good fresh water environment so corrosion concern is lessened.
