## Questions & Answers

**Q: Would this be able to take a 4awg wire?**
A: Yes, you can use a 4awg wire in your setup. That's what I'm using in my solar battery box. To get the 4awg wire to fit, you have to unscrew the main cap, unscrew the flathead screw to release and remove the red insert,  then strip the 4awg wire casing off and from there you will need to cut some of the strands off for it to fix. It worked for me.

**Q: Is the circuit supposed to be connected when the arm is up or down? I bought 2 of these and both appear to complete the circuit when the arm is up.**
A: The arm should be down to complete the circuit. If you have a multi meter that checks ohms, run a ohms check in the fuse itself. Up position should show an open circuit.

**Q: How many breakers in the package ? Two are pictured.**
A: They are a 2 pack. These are real good quality also.

**Q: Is this polarized?**
A: Not sure, but it is a breaker so I would not think it is. I do have a diode on one that is being used on a 24v to 12v buck converter.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very useful disconnect.
*by  on Reviewed in the United States 11 July 2024*

I use these all the time as a disconnect for the solar panel to the solar controller. As you know you must never have solar power coming into the solar controller if the battery is not connected. You can disstroy the controller if you do. I know, as I have made this fatal mistake, by mistake or ignorance. It can be costly. I use only MPPT controllers and they run around $150.00 and up. They also serve as a breaker for over power surges, for what ever reason. They are cheap insurance as well very hand when you need to disconnect the panel for any service work that must be performed. Always remember the breaker needs the be 10% larger than the current that the panels can produce. Solar is fun, let's be safe smart about it.

### ⭐⭐⭐⭐⭐ Work great
*by  on Reviewed in Canada 16 August 2022*

Work well with my solar system. Recommend.

### ⭐⭐⭐⭐⭐ Holds at least 20 Amps without overheating/tripping.
*by  on Reviewed in the United States 27 September 2019*

I've been through countless versions of these and find the amperage capacity to be hit and miss as compared to the "rating". I bought these 40a breakers to replace a couple of 50a rated ones from another vendor that were tripping at 20a. They stay cooler and have not tripped at 20a. The voltage drop is also a bit less than the bad 50a rated breakers were showing. (Which makes sense, since heating of the bimetal element due to excess current flow is what trips this style breaker...)
