## Questions & Answers

**Q: Is there a bottom or back?**
A: Yes the switch is fully enclosed except for the side you enter with the wire

**Q: These are listed as being rated for 275A continuous, but the manual this switch comes with says its only 200A continuous. Which is the correct rating?**
A: Thank you for your purchase.
The item you recieved is On-Off battery switch, and the pamphlet you recieved is 1-2-Both-Off battery switch, so sorry for the issue casued to you, the pamphlet may be mixed by our worker.
Fot the item you purchased X001H8MQTX (On-Off battery switch), the continuous rating is : 275Amps DC.

Also below are some tips for you to install the switch:
The 2 terminals are same, no negative and positive. Just like a switch, connected to the switch on both sides so when you flip the switch it cuts the circuit. 
More, recommend to install this cut off switches on the negative, not the positive (lower current in negative, will be more safety). 
The switch can be install in the negative wire, another short battery cable or cut existing cable and attach terminals on each end. 

Hope the info can help you.

**Q: How far from battery can it be installed?**
A: Mine is 2 feet from the battery, I don't think it matters. Your cable size will have to increase the further away from the battery that you install it.

**Q: If the switch is on off (red) is the battery not drawing or the disconnect is not engaged and battery still drawing? Over thinking I'm sure.**
A: battery 1 to switch,battery 2 to load side if you are using battery 2 too power stuff. if switch is off then battery 2 will power your things and not draw from main battery 1. To charge battery 2 turn switch to on then turn off when its fully charged if that makes sense

Bought as a main switch between battery and load with a circuit breaker, so will only get occasional use, but should be fine.
