Waterproof Inverter Circuit Breaker Holders Review

This is a very well built jackhammer and it works great. I used this on my driver between the test and the heater that is in my cabin during the winter. It was necessary to purchase bushings for the end of the cable and an aluminum mounting plate to install it.

The switch worked for a short time and then failed under load. The supplier was kind enough to replace it with a different circuit breaker (250A) even though the 30 day return window had expired. The replacement did its job and worked as it should, even under heavy loads. I use it as a protective fuse for the winch. I turn off the switch to turn off the feed when not in use. The connections/lugs are well made and hold up well. I was very happy about the reply and the replacement.

I bought the 300A version first to work with my 24V 3000W inverter to work. The product appears to be well assembled and the switching mechanism works well. Thought I'd like to use the set screw approach to save on buying more cleats. However, the set screw approach causes 2 problems. First, the maximum wire size is 1/0, which can only handle 150A. Therefore, they should not make circuit breakers greater than 150A with this cable configuration. Second, the info says it works with 1/0 to 4 gauge
