My 50 amp cord boot on the boat inlet side is ready for replacement. I thought an upgrade to a smart plug might be a good idea. Has anyone done this, and is It an easy replacement on the boat side? How are the waterproof properties?

This country boy wants to know what is a smart plug??
 
I like their 30 but for my boat a standard 125 / 250 50 has more than enough capacity and durability plus it's a standard if I ever need to borrow one. I can only draw 2 x 30 amps so I will change to the standard Hubbell 50 and never need to worry about overheating it. If I had the ability to draw more I might look at the surface area of the contact to see what was larger.
 
The Hubbell plug design dates back to the 1930s and what contact area it has (surprisingly little) can easily be reduced by just bumping the plug or cord with your foot as you walk by. I just replaced my cords due to an previous incident that could easily have burned up my boat. I am very conscientious about making sure that the plug is well seated and I am still getting arc burns. I know a number of people who have made the switch. It takes about 1 hour per plug. So for me, the Smart Plug with substantially greater contact area and positive placement and retention in the socket and the peace of mind that comes with that is the way to go. It is project #1 for next cruising season.
BTW, I have 30A service. Most of those that I know that have made the change have multiple 50A service (houseboat).
 
I switched to the 50 A smart plug as soon as the %0 came out (2 years after the 30) and would never use anything else.

great surface area makes for cool plugs on high demand days but the big convenience is no longer having to shimmy and twist and look into hot lugs to line up conductors. The shape allows for instant line up and the locking mechanism is bullet proof... no more plugs twisting loose oh and it has a terrific gasket making it water proof.

They are even contemplating a Hatteras logo molded into the cover.
 
Was it hard to get just the top 50 am inlet out? Ours has 3 inlets stacked in the boat inlet panel on port and starboard. Will just the top inlet come out easily?

I have also had some warm plugs, and think it is time for an upgrade.

Mine has three also, stacked but the 240/50a is on the bottom not the top.

All three are attached to a brushed stainless face plate that screws out so you can get to all three and service the inside of the box. So on mine, no problem, yours may be different. I occasionally get the willies from the fact that the face plate is steel and thus a conductor and think about remaking it with something fire retardant and non-conductive.

Perhaps like this, any thoughts anyone Am I just obsessing?

Update here, but not how I expected. In a new slip at homeport, and pedestal got hot and blew the breaker.
changed sides, told the staff, its time for an electrician to check it. 3 days later cartridge fuse got hot (I was in parking lot washing the center console), family on board in August heat.
Fuse cut out, and then came back online and melted. Pedestal never blew, nothing on my panel affected. Smoke. family ran out.
Post mortem. Hatteras design did its job. going to single use cartridge fuses. No damage beyond the box but burned up wire in the box. Electrician replaced that inlet with a smart plug to try, wires, fuse.
Clearly the Hubbell plug on my inlet was worn and an arc got created. YC replaced all of the pedestal parts-likely contributed to problem.
I also now run 2 cords when family is onboard. While this happened family decided (and I wasn't there to drop 2 AC's off) to run the dryer, microwave , 4 ACs were on, and a hair dryer. pedestal should have popped.
Electrician is old school, but very capable. Said if your Hubbell inlet plug no longer 'clunks' in when you twist it, then time for a new plug. 3 old boats and 30 years, I don't think that I had one until now that does that.
I do like the binary nature of the smart plug, and the tech of the new High Tides cord. He wired the smart plug to an extra, older 50 amp cord, since they do not make them anymore (charles got out of that biz).
Both plugs this weekend are nice and cool. No loads over 35 amps possible to either cord (30 and 20 seem to be peak). electrician suggested that a load over 40 amps, time to add a cord.
CHECK YOUR INLET PLUGS!!!! It may be time. My error here, but it all worked out fine. I always spray my plugs with CRC, but never til now had the 'clunk' of a new plug. smart plug eliminates that possibility, but tough market to penetrate.
stay safe!
 
correction, 4 air handler's on the 3 AC systems.
 
Be sure to get the updated one. The early versions used a plastic collar to hold the cable into the plug. The newer versions have a metal collar. The only downside with the newer version is you loose the auto reset overheat breaker. I had an older version melt due to a short. I called the company and all they required was a photo of the plug and they overnighted me a new one. Great service

Definitely metal collar...metal to metal. Electrician had to machine the receptacle into the panel.
Was not aware of an auto overheat reset feature. Maybe that is gone now. will check. good feedback. thanks.

When I plug in or unplug I always turn the breaker off. It stops the ark and preserves the life of the cord.
