Can you believe that your shore power plug was designed before World War II (in 1938, in fact)? While it has been in use for more than 70 years, it has several critical flaws.
Since it is symmetrical, we have all struggled with aligning the plug to the receptacle properly, while trying not to cross thread the locking ring on the boat's inlet. The original design uses curved blades with detents to hold the plug in the socket. The blades and detents themselves carry most of the force needed to hold the plug in place. The slightest misalignment of the plug in the socket caused by the weight of the cord and the tip of the detent moves out of the hole on the blade. Now a tiny contact patch where the tip of the detent is touching the blade is all that is carrying the current. The small contact area creates a high resistance connection resulting in heat buildup. Heat buildup in the plug is responsible for most boat electrical fires. Lastly, the "water resistant" seal on the plug is questionable at best.
The new SmartPlug system addresses all of these deficiencies:
Converting to this new system is easy and takes an hour or less using basic hand tools.
Here's what's included:
You simply remove your old plug and replace it with the new one. You will still be able to connect to shore power at your old dockside connection or in any other marina providing the old standard 30A service. Your boat will be protected.
Catalina Direct has never before offered shore power components in the past. Frankly, that is because every system available has the same dangerous design flaws. And no other company has had the chutzpa to go against the entrenched bureaucrats at Underwriters Laboratories who refuse to consider that a 70 year old design could be improved upon.
The many improvements provided by SmartPlug make this power supply system both easier to use and much safer. That's a combination Catalina Direct can get behind! With the added safety and convenience of this new system, we feel this is a terrific system that is worth having.
Note: This product is designed for American 120v systems. It is not appropriate for use with the European 240v system.
