Added cutoff switch to my battery box. Also, added voltage indicator and
accessory port for solar.

Aggreed! I am going to disconnect all electrical when i store it, ......JUST..... Disconnect the positive side of the battery.....no need for another swich. Take the wire off the battery post. Zip tie it off somewhare else. When you need it , screw it back on.

Using a switch or disconnect with a higher current rating than is needed will not cause any issues. Using fuses with a higher current rating than what they should be, may cause serious issues. And remember this, disconnect switches, like a battery isolation switch will have ratings for both voltage and current. If it is rated at let's say 50 amps at 12VDC, and you are using it at a higher voltage, the current rating will be less. Direct current (DC) will always have a tendency to "arc" when it is open if there is a load on it, so remember, when opening one, try to have the least amount of load on it as possible with the situation you are in...AND, operate the switch very quickly...in other words, don't lolly gag around when you are opening it, make it snap open. Just some random thoughts on the topic and things that you may already know, but it never hurts to remind...or enlighten!

battery switch vs disconnect

my opinion,
My Keystone Sprinter, like Just Beclause said, has a disconnect which does NOT disconnect the slide outs, leveler, or remote control items. I researched and decided that is good for me, I usually turn switch off but can still open slide and inspect now and then in storage.
The issue is of course, not everything is off, and I accidently left the patio light on (which remote turns on separate from the manual switch). Also, if you do any electrical work, disconnect is a must.

Safest isolation method is to disconnect the battery on the (-) negative terminal. Either remove cable or install a second switch. I recommend doing this for long storage periods (over month). Not much draw down in short time but you will need to charge up about every 6 weeks or so.
best regards,

Cut-off switch

Since the wiring is only good for 30A there is no need for a 500A switch. And the slides don't draw 100A. But here is what you can do. The power switches are on the positive side of the battery lead the may still be circuits that are "hot". The best way to overcome that is to simple re-wire the switch the cut the power on the grounf or negative lead. That way once activated there is NO power flowing in any circuit, which is really what you want. And a 30A switch from a auto supply store will work fine.

Happy camping.
