I'm sorry if the question is too dumb, but I was wondering if I could connect a power strip rated for 250v into my home's power outlet (120v). I wanted to connect 3 power adapters rated at 120v to it (that would then power up some effect pedals I have for guitar). Could the wire gauge inside the power strip be a problem? Because I thought that since the rated voltage support is higher, there shouldn't be any problem (I mean, resistors and eventual caps wouldn't catch fire, but would they some how underpower my power adapters?). Please correct me otherwise. Thank you!
Newbie question: can I plug a 250v power strip into a 120v power outlet (and then connect three 120v power adapters to the power strip)

You can absolutely share the same ground for as many voltages as you like.
Current flows to whatever loop is closed, so as long as you don't connect both positive and negative together the batteries won't even know about each other. That would be the easiest solution:

R1 sees only 12V, R2 sees only 24V and neither battery can ever see the other.
And you can also just connect them like this, same idea:
Just make sure the load doesn't connect between the 12V and 24V, you'll get 12V, but it will run through both batteries and cause trouble when one is empty before the other.
Page 16 of your manual:
2.2 DC and AC Voltage measurement
1) Connect the black test lead to "COM" socket and red test leads to the "VΩHz" socket.
2) Set the selector switch to desired “ V [squiggle]” position, and press “SELECT” key to choose function.(DC or AC)
3) Connect the probes across the source or load under test.
Best Answer
The answer may be both yes or no, depending on some details.
You will get a yes answer if, and only if all of the below are yes:
For point three, if the strip only has a wattage rating, I = P/V, use the highest voltage it can operate at to be safe, so 250V. So if it says 2500W, it can handle 10A. Which means for your adapters, try and stay at or under 1000W (100V * current) and you'll have used a little margin in both calculations and will stay on the safe side.
EDIT: Point 2 can get a no and the end-answer still be yes, but within the range of (over-)equipped power-strips there are sooooo many different functions and functionalities that it's a bit senseless to add all the options, since I'm not in the mood to write a 110 point list.
