Wanted a cut off switch instead of disconnecting terminals each time. This is supposedly rated for 250 amps. I don’t currently pull that much power so far it’s working great. Note terminal size is 3/8 so plan accordingly when buying or making cables.

My marine boat did not come with a master Killswitch. this is the one that I purchased to install in my boat, and I couldn't be happier. It was easy to install with basic electrical tools and equipment. No problems with corrosion (yet). Now, there's no risk of damage to equipment or dead batteries if someone forgets to turn off some electronic equipment on the boat, because one switch does it all.
