Hello,

Thank you for stopping to read my post.

I am trying to help my grandmother locate the breaker for a 250v outlet as she needs a new dryer in her house and is switching from gas to electric.

If the picture came through correctly, would anyone here have any suggestions on which of these might be connected to said outlet?

From what I could find online so far, it's supposedly one of the breakers with two switches attached together. I'm just not sure which, as the outlet itself says 50amps and none of these specifically list that number on (what I assume) is the amp amount marked on the switches. All the electrical at this house is so disorganized no one knows what's what right now (which I am definitely going to hire an electrician to remedy soon). And I also don't have anything to plug into the outlet to simply switch things on/off and see if power gets cut to it and she needs a dryer sooner than we'll be able to hire said electrician.

I'm hoping to test the outlet before getting her a dryer, as it just hasn't been use for almost 2 decades, which I read requires switching off the breaker for the outlet prior to connecting a multimeter but I'm limited on what I'm familiar with electrically, and money is extremely limited so trying to save her money by doing what I can before getting an electrician called in for anything significant.

Any advice, suggestions, or direction are greatly appreciated.

Either way, thank you again for taking the time.

Hooking up a voltmeter to an outlet with no power because the breaker's off isn't going to tell you anything, other than there's no power on that outlet, but you won't know why unless you leave the meter connected and then turn the breaker on to verify.

Now may be a good opportunity to label stuff - start with turning breakers off and determining what goes dark - label those accordingly. Inventory the outlets, find all the 220/250 ones - those will be on these double breakers (including electric water heat).

You'll then be left with only a couple unknowns, probably just one, since the dryer circuit doesn't have anything on it.

I've gone so far as to put a label on each outlet using a labeler with clear tape in it.

Edit: Pretty sure a dryer outlet isn't going to require a 100amp breaker, so ignore those.

Looks like there's ~~3~~ 2 double breakers rated for 30 amps, it's most likely one of those - #9 and #29.

Edit2: Could also be a 60 amp circuit, though I don't know why a dryer would need 60amp at 220/240 these days, but I'm not an electrician.

(just commenting on your edits)

Well, OP did say the outlet is labeled for 50A, but that doesn't really narrow anything down reliably. You could still wire two single pole 30A breakers for 220. Granted, that is really stupid but not beyond what someone would do in a pinch.

Given that there isn't any visible labeling, I would err on the side of caution and test and label everything like you said.
