## Questions & Answers

**Q: ia this product waterproof?**
A: Dear Customer,This item is water-resistant not "water-proof".  Marine Grade Battery Switch.AC DC Marine Inc

**Q: Can I use the isolated dual circuit one to disconnect the + and - of one battery to completely disconnect it?**
A: This switch is exclusively for the cabling to the pos+ terminals only.
The negative- terminal needn't be disconnected to isolate the battery... after the pos+ is switched off, the battery is definitely in disconnect.

**Q: Can you use this for higher voltage, but much lower amperage? i want to use this at 52-60v dc at under 10a.**
A: I am not sure.  With 52-60vdc, its internal circuit may not able to handle.  However, under 10A should not affect its operation.

**Q: Can I use this in my RV to shut off both the house battery and the engine battery**
A: I would think so, if you wire both batteries to the switch - it has an off position.  However, I'm not sure it is wise to wire your engine battery to this - if you need to run them both at the same time - I've been told the batteries will equalize charge if you use the 1+2 position.  That may cause a low house battery to discharge your engine battery if that is true.
