Smart Plug

Much boat time is spent working on essential projects. When docked boats are connected to electrical service or shore power by use of a heavy power cable with special plugs found generally in the marine and RV camping worlds. The standard NEMA L5-30R Female and L5-30P Male Twist-Lock connections are decades old technology, which is subject to failure primarily due to physical stresses on the connections.
You can see from the photo of the old plug ends how the connectors were arcing and burning through the insulated material. A complete failure was in my near future.
Newer and considered by many people to be superior design is the Smart Plug. Time has come to replace these connectors on CaiLeigh Anna. The Smart Plug design features a stronger direct locking connection that resists the dangerous horizontal stresses that lead to failures in the older and more traditional plugs.
Bottom line is that we have a much safer electrical connection system on CaiLeigh Anna.
