  • Worth the money
Color: WA80A
I had bought one of these for a truck I was fixing up because I was going to install a stereo system in. I discovered the previous owner had already had a electrical fire because he had run a power wire to a amplifier without a fuse of any kind and when he did the repairs he had run the wire again without a fuse. So I bought one of these and put it in line. I used that one to run all the electrical and put a way heavier wire and breaker in for the amplifier with no problems at all. Now I'm setting up all new wiring for a small boat and using this between the battery and the fuse panel since they are about 4 feet apart at least. ... show more

  • Great circuit breaker, but terminals are too small
Color: WF200A
I use these breakers on many installations. A 200 amp circuit needs large wire size and the terminals don't accomodate many of the wire lug sizes.

  • Very good product for the money
Color: WA50A
I used this for power from my battery to my add-on Accessory block up front in my UTV. Works perfectly for this application. Works perfectly with 8g wire, as seen in picture.

  • Ease and peace of mind
Color: WA40A
Added these to multiple points on my camper to give an easy cut off to the solar charger, 12v supply to camper and a bigger one on the battery. Seem to work great, but haven't tested tripping them with a load, so hopefully they trip at the rated amps.

  • Cheap breaker. Undersized terminals
Color: WF300A
Trips well before 300 amps for 12 volt system . Terminals are way to small for 300 amps. Bought a 200 amp breaker similar that costed more had double sized Terminals and first tripped over 200 amps. You get what you pay for.

  • Way Better than Getting an In-Line Fuse !!
Color: WA40A
This is waaaay better than getting an in-line fuse. You NEVER have to buy another fuse again, because it has NO fuse . Also, you can cut-off the power to you amplifier, if you need to adjust your cross-over sound settings for your mid-rage and high speakers. My sub is a 15-year old Infinity BassLink. And I am running it with a Pioneer AVH NEX-2550 head unit. My stuff is BANGIN' HARD now. This is because the 30-watt blade fuse I originally had under the hood was weak and restricting proper flow to my amp. With this breaker my 15-year old sub sounds waaaaay better. I never new it could BANG that good. And sounds cleaner too. =========== INSTALLATION was a breeze. 1) - UN-hook just the positive cable and put the terminal on a cloth so it does not touch any metal by accident 2) - Strip about 1/2 inches of the protective sleeve off the Audio cable for both the ends that will go into the Fuse Breaker Switch 3) - Jam the wire as far as it will go into both ends of the breaker 4) - Screw down the wire cables with an allen-wrench. 5) - Make certain to have the clear and red protective caps screwed back on for a water-tight seal 6) - NEVER, EVER install this breaker close to your amplifier. You just need to install it as close as you can to the car battery. About 6-inches of cable or so. 7) - For SAFETY, I made certain to have the breaker switch in the "OPEN" position BEFORE I attached it to the battery terminal. 8) - Connected to the battery terminal. Turned on the car and radio. 9) - Closed the breaker switch 10) - Viola! All done, son !! =========== ADDITIONAL NOTES : For my 200 Watt amplifier, I got a 40 AMP. IMPORTANT: Make certain to get just the right amp amount that SAFELY matches particular wattage of your amplifier. NOTE: Purchasing too high of an Amp for the breaker is like having NO protection at all. Hope all this helps. ... show more
