This electrical box is much smaller than the older one I had cause it has a different design. The electrical contacts feel very solid and durable

I like this box. It's a bit more compact than a typical disconnect and looks tidy

Highly recommended. The box is very robust. I prefer in-line fuses due to considerable power surges in my area that can damage the equipment. Just make sure you have an extra set of fuses in case of a blowout. Plenty of room for wiring

Where can I find replacement parts?

The manufacturer doesn’t offer replacement parts. The entire disconnect should be replaced when needed
Can I use this for a220v 20 amp breaker with 20 amp fuses?
