Video Transcript for Hopkins Trailer Breakaway Kit - Kit with Charger - HM20001 Review

Today we'll be reviewing part number HM20001. This is the Hopkins Trailer Break-Away Kit with a charger. So what you're going to get is you're going to get the Break-Away box, which is a switch. You're going to get the cable and it has the plug-in and the plugs into the back side of the switch. You're going to get the battery box that is locked with the screws, so that is sealed shut. You got the expose wires coming from the rechargeable battery and from the switch, they are all going to be color coded. You have to options when it comes to mounting. You can either choose the mount using the U-bolt setup with the washers and the lock nuts.

Or you can use the self-tapping screws with the washers and the lock nuts, whatever is best going to suit your application, whether you mount to your trailer frame or to your jack. It has the battery charger system which is great to have. Lockable weather resistant battery box. Inside is going to be a sealed 12-volt rechargeable battery. Once you have everything wired correctly, that will charge on its own. The Break-Away switch, this can be mounted somewhere close enough that you allow yourself enough cable to reach to the tow vehicle. What a Break-Away switch kit does is this system is designed to bring trailer safely to a stop by activating the electric trailer breaks, should the trailer be disconnected while driving. For instance if your safety chains we're to fail, then the Break-Away system would be use as a last line of defense.

This type of safety system is usually required in most states on trailers made it over 3000 pounds. The box can be mounted on a trailer jack or trailer frame. It's going to work with single axle and tandem axle trailers with electric breaks. This Break-Away kit system does meet DOT specifications. The wiring on this, on your switch you're going to find a black and a blue wire. The black wire is going to connect to the trailer break system. The blue wire is going to connect to the blue wire coming out of the battery box.

Here at the battery box, you have the blue wire which connects to the break switch. You have the black wire which is going to be your charging circuit wire. Then you have your white wire, which is going to be your ground wire. All those cables are expose, all you got to do is splice the ends to expose the cable itself. They're nice and coated, they are going to stand up well against the elements. We'll go over a few measurements real quick. The switch itself from end to end including the mounting slot, it's going to measure three inches.

You can see here on this end of the switch that we do have a mounting hole to firmly secure it. When mounting this, you do want to make sure that you don't have any obstructions in line of the pool or the Break-Away cable. You want that to be nice clean pool or disconnect if that was ever come disengaged. The overall height of that switch box is going to give us about 7/8 of an inch. The battery box overall width is going to be about 7 inches. The overall depth is going to measure about 5 inches and then our overall height is going to measure right around 3 inches. That's going to do it for today's review of part number HM20001. This is the Hopkins Trailer Break-Away Kit with a charger. .

I have not installed this yet but have looked over everything I received with this kit. I couldn't be happier with the it. There are only a few pieces needed that aren't included and they are choice of electrical connectors and a seat tapping screw to attach the switch itself. Everything else is in the box. The instructions are clear and easy to understand. I will be attaching this to the trailer Jack on a 1962 Airstream Ambassador. 571729

Ordered this on Tuesday - arrived on Thursday... awesome delivery time! Bought this to put on my 1996 Coleman/Fleetwood Shenandoah popup camper since for some reason ours didn't come with a breakaway kit. Wanted to mount the battery and charger box on the tongue of the trailer, but the supplied U-bolts that came with the kit will NOT go all the way around the rectangular frame rails of the trailer tongue. Ended up going to the local big-box hardware store and buying some threaded rod and made my own mounting brackets. Instructions included are very easy to follow. Only thing I saw that was missing in the kit that you'll need for installation was a package of tap-splice connectors for connecting the breakaway switch and the battery and charger to the existing trailer wiring. 55391

Ask the Experts about this Hopkins Trailer Breakaway Kit
Do you have a question about this Trailer Breakaway Kit?


  • Battery Charger for Trailer-Mounted Auxiliary Battery
  • A trailer breakaway battery charger kit like # 20011 will be needed only on a trailer that does have electric drum brakes and a breakaway system like the Hopkins # HM20001. For maintaining a trailer-mounted battery that supplies power to lights, vents, etc you can use the 12V power circuit in the 7-way connector. This 12V feed is carried on the pin at the 1-o-clock position as you view the 7-way socket. Please refer to the linked photo and article. This 12V feed has enough power to...

  • Recommended Wiring, Junction Box, And Breakaway Kit For 18-Ft Tandem Flat Bed Trailer
  • To re-wire your 18-ft trailer you will need a few things. I recommend installing a junction box like part # PK52248. You can run your trailer connector like part # H20044 to the junction box and use the terminals in the box to run the wiring to the trailer. For 7-way jacketed wire I recommend part # DW04914-1. This is sold by the foot. The junction box will also make it easier to install and use a breakaway kit like part # HM20001. This kit includes a charger and a weather-resistant...

  • Difference Between Hopkins Breakaway Battery Kits HM20001 and 20099
  • The big difference between the Hopkins Engager breakaway kits is that the # HM20001 does not have a charge status display on the lid like the part # 20099 does. The # 20099 allows you to press a button and know what the charge of the battery is like.

  • Trailer Breakaway System Recommendation for a Tri-Axle Trailer
  • If all 3 of the trailer axles have brakes you will need one with enough amperage to be able to apply the trailer brakes on full for at least 15 minutes. The Tekonsha system, # 50-85-313 will work with 1 to 3 axles. I have included a link to a video review for you. Another option is # 2028. I have also included a link to an FAQ article on installing a breakaway kit.

  • Parts Needed To Add Electric Brakes On Motorcycle Trailer
  • When adding brakes to a trailer the first thing you will need is a brake mounting flange on the axle. If you do not have a brake flange I recommend part # 4-35. This should be welded in place by a professional welder because it needs to be square and concentric. The brakes I recommend for you are part # AKEBRK-35L-SA. These are self-adjusting 10 x 2-1/4 inch brakes and will work with 13, 14, and 15 inch diameter wheels. This is the brake for the left hand(driver side). For a brake...

  • After Installing New Breakaway Kit on Trailer the Brakes Lock Up when Connected to Different Truck
  • It sound like you are describing the Engager breakaway system, # 20099, or something similar. The lights indicate the charge level of the breakaway battery. The issue when you plugged in the trailer to the friend's truck could mean that the connector on his truck is not wired the same as it is on your truck and trailer. I imagine that if the brakes were locked up when the trailer was connected to your truck you would have heard the tires scraping the ground or someone would have flagged...

  • Parts Needed for Installation of Electric Brakes on a Coleman Pop-Up Camper With 8 Inch Wheels
  • The 8 inch diameter wheel on your Coleman Fleetwood pop-up camper is not large enough to accept an electric brake hub and drum assembly. Seven inch brake assemblies like # 23-48 that you selected work with the Trailer Hub & Drum Assembly, item # 8-257-5UC3, which will fit in wheels starting at 10 inches in diameter. You would need to upgrade your wheels and tires to either a 5.30-12 load range c wheel and tire combination, or a 205/65-10 load range c wheel and tire to meet the capacity...

  • How To Move A Trailer With A Dead Breakaway Battery
  • On most breakaway kits such as the Hopkins Brake Master part # HM20001, you will not need to cut or splice any of the wires to move the trailer with a dead battery. If your power supply is not active, then the only effect is that the breakaway system will not send power to your trailer's brakes in a breakaway situation thus allowing for free movement of the trailer. Even if the battery is dead, the brake controller will still allow you to activate your trailer's brakes To prevent further...

  • Theft Prevention Recommendations for a 5th Wheel Trailer
  • You could remove your breakaway switch pin while your trailer is in storage, however, a determined thief will get what they want in the end. If he went through the trouble to break in and attempt steal your trailer, it would not be a problem for him to simply cut the wires from the breakaway switch. Cutting the wires from the breakaway switch would be fast and easy. Another factor to consider is that the battery will only last for a short time and it will drain completely. Leaving the...

  • How Much Force does it Take to Pull the Pin on a Break-Away Kit Switch
  • It is a simple switch, so brand compatibility should be a non-issue. When the pin is pulled, two pins are allowed to contact and complete the circuit to engage the brakes. Any switch should work fine. I pulled the Hopkins Switch, part # HM20010, to test it out. It does take a good tug to pull it out and close the switch. You should not need to use two hands, but it should not easily slide out. You do not want the pin coming out when you hit a hard bump. I would not repeatedly pull...

  • Can the Trailer Breakaway Battery be Used to Power a 12 Volt Interior Light
  • You will want to use a standard 12 volt deep cycle trailer battery to operate the interior light. You will NOT want to use a trailer breakaway battery. The breakaway battery is not designed to power other trailer accessories or lighting, it is just designed to operate the breakaway system. The DOT regulations state that a trailer breakaway system needs a dedicated battery. To keep the trailer battery charged you will need to run a 10 gauge power wire like the, part # 10-1-1, from the...

  • Can Trailer Be Towed if Battery in Breakaway Kit is Dead
  • Your trailer's brakes will not lock up from the battery in a breakaway kit, like the Hopkins Brake Master # HM20001 being dead. If the breakaway battery is dead there won't be any power supplied from the system and it wouldn't have any impact on your brakes. Your breakaway battery should be tested before towing. If it's dead then it will not be able to do it's job of engaging your trailer's brakes in the event your trailer is separated from your tow vehicle.
    view full answer...

  • Can Trailer Brakes Lock Up if a Breakaway System has a Dead Battery
  • No, if the breakaway battery on the trailer is dead and the pin is pulled out of the switch then no power would be sent to the trailer brakes and they would not lock up. If they do lock up then the brakes must be getting power from another source or the battery isn't dead. I recommend checking the wiring for shorts and corrosion and fix any pinched or damaged wires as needed. If you suspect the breakaway system is bad I recommend replacing it. One of the most popular systems we carry...

  • Parts Needed to Add Electric Drum Brakes to Trailers with 2,000 lb Axles with 5 on 4-1/2 Wheels
  • To add electric drum brakes to your trailers the first thing you will need are brake mounting flanges. There are different ones for different diameter axles. Given the lower capacity of the trailers I am guessing the diameter of the axles is 1-3/4 inches at most. That is the smallest brake flange there is, # 4-34, for 2K axles. Anything smaller or that isn't common will require a flange to be fabricated. A note on welding them on: generally it takes a special jig and someone with experience...

  • Tow Dolly Recommendation for Towing 2018 Toyota RAV4
  • The Roadmaster Tow Dolly part # RM-2000-1 would be a great dolly to use to tow your 2018 Toyota RAV4. Your wheel size would not be an issue either. This comes with wheel nets that will fit well and brakes so you'd be set. The Roadmaster Tow Dolly # RM-2000-1 does not come equipped with a breakaway system but you can certainly add one. I recommend the Hopkins # HM20001, because of how easily it installs. They aren't a requirement but it would be a great idea.

  • Will a Breakaway Kit Damage the Brake Controller if Tested with the Trailer Connected
  • I would disconnect the connector before testing so that you do not back feed power to the Prodigy controller. This is the best way to ensure there is no damage to the controller and to be sure the breakaway system is functioning properly. The breakaway is designed to work when the trailer has detached from the vehicle so the electrical connection would be severed. Most Brake controllers are protected from back feed so if you did test the breakaway with the trailer connected you should...

  • What is the Function for the 3 Wires Coming out of the Charger
  • The 3 wire component is the charger and receives 12V power from the vehicle connector and charges the breakaway battery. Now the blue wire coming off the charger will go out to the breakaway switch. I included a video on a similar charger # 20011 for you to look at. It will have the same functions as your charger.

  • Maintenance Charge for a Trailer Mounted Battery through a 7-Way Trailer Connector and a GMC Acadia
  • To supply a maintenance charge to an auxiliary battery you would connect the 12 volt circuit from a 7-Way trailer connector to the positive terminal of the battery. If the battery is mount on the trailer you would ground it to the trailer frame and it also would not hurt to ground it to the main trailer connector ground. This method will provide a maintenance charge like you have said but it will not charge up a battery. For a battery charger I recommend the CTEK 3300 charger # CTEK56158.

  • How to Reset the Hopkins Trailer Break-Away Kit with Charger # HM20001
  • You are correct. The system does not have to be reset electrically to allow for normal trailer operation. Instead, like you said, the pin, or what separates the contacts, needs to be put back into place. What happens is, if the trailer detaches from the tow vehicle, the mechanism separating the pins is pulled out. This allows the contacts to touch which in turn engages the break away system to stop the trailer.

  • Recommended Break-Away Kit for the Roadmaster 2000-1 Tow Dolly
  • The Roadmaster Tow Dolly # RM-2000-1 does not come equipped with a breakaway system but you can certainly add one. I recommend the Hopkins # HM20001, because of how easily it installs. I have linked an installation video of the Hopkins Break-Away being installed on a trailer for your convenience.

  • Troubleshooting Lighting on Snowmobile Trailer that Doesn't Work
  • You have the issue isolated to being on the trailer somewhere. What you will need to do is first check that the trailer connector is clean and free of any corrosion as that's the easiest thing to check. Next you will want to check the conditions of the ground wire from that connector to the frame of the trailer. Since all of the lights aren't working it makes me think the main ground that feeds all the lights isn't sufficient. Aside from that it could be a wiring issue to the assemblies...

  • Should the Cable on Hopkins Break-Away Kit # HM20001 Engage Trailer Brakes If Safety Chains Break
  • The breakaway cable on the Hopkins Break-Away Kit, part # HM20001, should engage the trailer brakes if the trailer becomes disconnected from the tow vehicle and the safety chains fail. So you will want the breakaway kit to be the last line of defense against a runaway trailer. As far as length of the breakaway cable, that will be determined by where the breakaway kit will be installed on the trailer. I am including a link to a FAQ page on breakaway kit installation and a link to a...

  • Can a Breakaway System and Brake Controller be Installed at Same Time on 2002 Dodge Grand Caravan
  • You can have both a brake controller and a breakaway system since they serve 2 different functions. A brake controller, which may be required by law in your area (check local and state laws) will apply the trailer brakes when you apply the tow vehicle brakes. A breakaway system only applies the brakes should the trailer become uncoupled from the tow vehicle. In many states a breakaway system is also required by law. The breakaway system needs to be able to apply the trailer brakes on...

  • Trailer Brake Magnets not Not Working on Snowmobile Trailer Towed by a Chevy 2500 HD Silverado
