Video Transcript for Buyers Products Auto Reset Surface Mount Circuit Breake Review

Hey everybody, Ryan here, at etrailer Today, we're gonna be taking a look at and showing you how to install the line of buyer's products automatic reset circuit breakers. Using a circuit breaker and your electrical application is very important. And that's because it's going to protect that accessory if they short or electrical issue we're to occur. So whether you have it on a pump, a plow, a wench, whatever the case may be, It's never a bad idea to add a circuit breaker. So a circuit breaker, let's get to work, kind of similar to how your circuit breakers work at home. So if you think about it I'm sure we've all been there where you have a bunch of different things running at the house at once.

And it overloads that circuit and trips the breaker, and that protects not only all those items that you we're running, but it's also going to prevent a fire. All that current would have continued to draw through their overheat a fire could potentially happen, and this is more or less going to work the same exact way. So how it works is current is going to run from your power supply through a contact inside of this breaker and out to the other side to your accessory will that contact in there is designed to more or less accept a certain amount of heat because electrical current generates heat. And so once that current draws enough heat or creates enough heat past the breakers threshold that's going to trip the breaker. That way the power will get shut off to your accessories and you don't have to worry about damaging anything.

This breaker is an automatic reset. So what that means is how I mentioned that heat goes through that contact and will cause it to trip if there is an issue. So once that contact in there cools down enough, it will complete the circuit again on its own and give your accessory power. Now, just to kinda give you a comparison there's also manual resets, which is this one here. So you can see they're very similar.

However, if this breaker trips it'll actually open that up and it will not automatically reset you'll have to come back here and reset it to complete the circuit. And that has some advantages. If there's a big issue, you're not gonna have to worry about this resetting on its own and continuing to send power. But on the other hand too, if it's something simple, you are gonna have to come back here and reset it and deal with that. So kinda just your personal preference there on how you wanna set yours up, but either way whichever breaker you do decide to go with it's gotta keep that electrical circuit protected.

So there is a lot of different size circuit breakers as far as the amp draining goes. And there's a few different ways you can figure out which one that you will need. A lot of times, whatever accessory you're trying to power up. A lot of times there's a label or some information on it that will tell you how many amps it draws and what circuit breaker you would need. If that information isn't available you could always reach out to the manufacturer. And nine times out of 10 they're gonna have a recommendation for you right off the bet. And if all else fails, you can also use a what's called an amp meter and turn those accessories on whatever you're trying to power up and measure the amperage that it draws. And then you could go from there you could pair it up correctly to what size breaker that would work best for it. So this is a type three breaker, and it's designed to work with accessories that use anywhere from 12 to 42 volts. So really gives you a wide range and we'll work with pretty much, most common type accessories. So at the end of the day, adding a circuit breaker to your electrical system is never a bad idea and just a really good way to make sure everything stays protected. So before we actually install this I figured we could just kinda take a quick look at it right out of the box. First thing I noticed is it feels really solid, well-built, there's really not any give to it at all. So that just feels good in your hands. You know, the top portion here, this cap it does have a rubber seal that runs all the way along each side of it. And that's, what's going to help keep this waterproof. And there's just a couple things that stuck out to me as well that make it pretty convenient. These rubber caps here will help keep studs protected. And more importantly, if you do happen to bump into it You're not gonna have to worry about, shorten it out or anything like that. Each stud does give you a label of auxiliary. So you know to hook up your wire to that auxiliary side and the other one will be labeled battery. So you know to hook up your power source for this stud. So they really make it straightforward and easy to work with. And I will say, once you start getting into some of the larger amperage circuit breakers so this is a 50 amp one. Here, just to kinda give you a comparison. Here, we have a 200 amp one. You could see that the larger amperage is this a little bit bigger. And really the reason is the studs are gotta be larger. And that's because whenever you use things that draw more amperage your wires are going to be thicker and larger. So you're gonna want these larger studs to put your ring terminals over. So just something I wanted to mention and kinda give a quick comparison. As far as getting these installed, they're really straightforward, more or less, you're just gonna have to secure it and then hook your wires up to each terminal. So really not a whole lot to it. And today we're gonna be putting this on a boat to protect all of our accessories, on pumps, lights, things like that. With that being said though, these do have a ton of different uses, pretty much anything a lot trick you can use to protect whether you have a, some type of pump, maybe a plow, a wench whatever the case may be. These are all going to get hooked up the same way. So to actually get this installed, first thing you wanna do is disconnect your power supplies. So whether you are under your batteries or in our case, we have a disconnect switch. We got that in off position. So we know none of her wires are hot and then we're gonna find a spot to mount it. So in our case, the wires that we're gonna be hooking up for our, all of our accessories are right here. So this is the power supply wire and this actually goes to the switch panel. And so I'm just gonna mount it right there. Now what I've done is just kind of held it up and pre drilled a couple of holes. And that's because I'm using aluminum self-tapping screws because this metal is aluminum. I would recommend picking up some self-tappers to secure this, it does not come with them. And what I'm gonna do, is this put that in and secure it down. I'll keep in mind how I mentioned that there's a battery post and auxiliary post. You wanna make sure to orient this in the correct way. That way you're not trying to stretch your wires way out or anything like that. But that being said though, go ahead, get it lined up. I'm just going to kinda get both of these started take our gun here and run them down. So from there, we need to do is pull off our rubber cap there and remove the nuts. Careful when you're pulling these off, it seems like, right when you get to the very end they almost kinda come off when you least expect it. So you don't wanna drop it. And I have to deal with trying to find it carefully, pull it off. Then, as I mentioned, you're gonna take the wire that comes from your power source or your battery. Put that onto the battery post. Then the wire that comes from your accessory and over the other posts we'll just take our nuts, get them hand tight and then we can come back and snug them down. Snug them slow, We'll just go ahead and pop these rubber tabs back on. So once you have it hooked up, you can go ahead and reconnect your power supplies. So we'll just turn our batteries on. And then it's not a bad idea just to test out your accessory to make sure that it is functioning properly. Go ahead and power up our switch panel. You can see the lights illuminate. We have battery voltage. And if I turn on some of my accessories you can make sure that they're working. And that'll finish up our look at and our installation of the line of buyer's products, automatic reset circuit breakers..
