The Problem

Contrary to popular belief, the #1 cause of shore power failure and fires is not electrical shorting, but rather overheating caused by poor electrical conductivity. How does this happen? The problem with many plug designs is the shape of the electrical pins, which allow for very little contact area. The pins are also largely responsible for bearing any physical stress placed on the cord (from constant movement of the boat, someone tripping on the cord, etc.)

SmartPlug The Problem

This results in the pins working loose, further lessening the precious little contact area they had to begin with. Furthermore, such loose connections allow for moisture intrusion and ultimately corrosion of the pins. Arcing occurs and the connection heats up, scorches, and in some cases, catches fire. Because the current draw is unchanged, all of this happens long before a breaker or a GFCI can cut the power. Additionally, the old design can be very difficult to use in low light or hard-to-reach scenarios since the L-shaped pin must first be located and then oriented before connection.

The Solution

SmartPlug The Solution

SmartPlug's 4-Stage solution protects against overheating every step of the way. Loose connections are addressed by a sleeve design and multi-point locking system which take all the physical stress off of the pins while securely fastening the plug to receptacle. Pin contact area is increased by more than 20x and protected behind three weatherproof seals for a dry and corrosion-free connection.

Twist-Type Design Problems

Twist-Type Design Problems

  • Curved electrical pins means minimal electrical contact
  • Visible gap between body of plug and inlet housing allows or movement of plug within the inlet
  • Nonexistent weatherproofing
  • Difficult to orient in low light or hard to reach scenarios

Video Transcript for Review of SmartPlug RV Power Inlets - Replacement White 30 Amp Power Inlet - SM57FR

Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at this smart plug replacement, 30 amp RV power inlet. This is going to replace your smart plug inlet so that you can get your RV hooked up to your shore power. Again. Now this is a white 30 amp 125 volts, male inlet.

So it will accept your 30 amp female connector will plug right in there, click in. So it's nice and firmly connected. Now this is the connector is sold separately. So if you are just wanting to replace the inlet this is a great option for you. If you're wanting to switch over from an older style twist type inlet I would recommend maybe going with one of our kits available [email protected]

It comes with the cable and the inlet. So it's going to help you convert your whole setup rather than just the inlet because you will need a connector that fits in there because this is kind of a proprietary design. So it will only fit into one way. But if you are looking for a replacement for a smart plug inlet that you've already been using and this is going to be a great option for you this is the white option. There's also a gray, a black and a stainless steel.

So you want to make sure that you're getting the one that works for your color scheme and a RV setup. This is going to be very easy to get installed. They do include instructions with pictures to help you every step of the way. They also include a hex key to get those wires tightened down so that they're going to have a nice firm connections of the adhesive foam gasket is included as well, so that you have a nice firm connection on the backside there. So everything that you're going to need to get your original smart plug replaced is going to be included in this is going to have all the same features as that original.

It's going to have the straight nickel plated brass inlet pins. So you're going to have a maximum electrical transfer going back and forth or coming in from your short power. It does have the sleeve design. So it's going to keep the weight off those pins. So if you we're to trip over your quarter or something like that, those aren't going to get jostled become loose. This is going to have that straight on connections. So it's going to be very easy to plug in and even in the dark, it only goes in the one way. You're going to have the weatherproof seal preventing water from getting in the inlet cap does have that weatherproof seal there. That's going to snap closed and create that nice waterproof closure there when you're not using it. And then the cap will also close down onto the connector when it's plugged in to help give it an extra little bit of resistance from pulling out. This is constructed of a plastic resin that is UV and heat resistant. So it's going to be very durable for you. It's made here in the USA, so you can trust. It's made to the high quality standards that we've come to know and trust for products that are made here in the U S so if you are looking for the 30 amp white inlet for your smart plug system, this is the way to go. Like I said, if you're wanting to switch your whole system I would recommend going with one of the kits and we also have other colors available if you would prefer one of those other colors. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..
