Review on Protect Your Vehicle With Jtron Car Battery Disconnect Switch - Waterproof, Cut-Off Isolator Switch For Cars, Boats, RVs, ATVs And More (50V, 50A Cont/75A INT, NO-OFF-OUT) by Ryan Bowers

I'm a retired electrical engineer, but you don't need to be an engineer to look up ampacity charts.I have no idea what this company it trying to pull, but there is NO WAY 6-AWG cable is going to carry 300A safely.At 60C/140F, here are the general safe current capabilities of the gauges they are selling here. The claimed value in the description is in square brackets:6-AWG: 60A [300A]8-AWG: 40A [100A]10-AWG: 30A [50A]Don't just take my word for it, look up "copper ampacity." I see so much unsafe recommendations and products that it's scary. Many people wouldn't know and trust that the seller knows their products. but sellers just sell.Be careful with what you're buying and always double check specifications. How much are you willing to bet that the switches are also grossly exaggerated in current carrying capacity?
