Anyone know what the modern version of this is?

Good afternoon fellers,

This panel is located in one of my sheds that i want to take down. the shed is very unsafe. When the shed is removed i want to update this panel. From the house panel feeds this panel with 240v then somehow converts it down to 120v to power my well pump and shed lights. there is an unknown device at the top too.

Thank you in advance for your wisdom.

50 AMP panel?
 
Get ya a breaker box with as many slots in it as you need. Always good to have a few extra. Would be pretty easy to change as long as you know what wire feeds everything. The two main hot wires put in a double 50amp breaker at the top of the box and that’ll make it a main breaker so you can shut it off without having to go in the house. The rest is just sorting out what hot goes to what. Put a ground rod in the ground outside to ground the new box to.
 
Also whatever that unknown device is, should not be connected to line side power. Odds are though that it's feeding something else on property. Old, unlabeled, electrical gremlins.

Thank you,

Will that convert the 240v down to 120v for my well pump and outlets?

Sure your well pump is only 120v?

I hooked up a voltage meter to the top black wires and they read 240v, then i hooked up the meter to the bottom yellow and red, and those read 120v.

UPDATE: i found a separate wire coming from somewhere else that that feeds my well pump with 240v. you are correct @Burt Gummer

So what i would like to do is rewire my well pump properly back to this box with 240v.

and next to it i would like to convert it to 120v for an outlet.
 
If you’re rewiring the whole thing, it’s not gonna look just like your drawing. Get a standard breaker box. The two 120V hots coming in will connect and provide power.

A double-breaker in the new box gives you a 240V output. A single gives you 120V. You set it up for the number of circuits you need.
 
the 2 hots will be 240v across each other. to get 120v you will need one hot and a nuetral.

not trying to be disrespectful, but if this isnt familiar, you may want to reach out to an electrician. this is simple stuff once you know it, but doing something wrong can become very costly, very quickly.

no disrespect taken. Through my neighbor's search plumbers, electricians, or someone who can completely remodel her bathroom, I've realized nobody up here is reliable, or we just haven't found someone reliable and affordable.
 
Larger fuse panel replaced with modern breaker panel but good info worth watching.

Thank you, if i am understanding you correctly, this is what i would like to achieve. What do I need to achieve this?

You just need a panel box and appropriate breakers. And as others have said you need help from someone who knows. Not knowing with this stuff can get you seriously injured or seriously dead.

Fixed it.

As others have said, install a sub panel with breakers. Don't be reluctant to hire an electrician if you are not 100% confident that you can do it properly.

I wonder if that unknown device is a photocell?

I’m pretty sure that the device on top is an older model of surge arrestor.
 
Looks like a 3-wire fed panel, think you must upgrade to 4-wire.
 
The thingy on the top looks like it might be a MOV that somewhat protects the circuit from lightening surges.
We put one on our KY home.

Late to the party. I just did this, but as a new install. Latest code requires GFCI/AFCI breaker and 4 wire feed to sub panel and the sub panel must have isolated neutral and two ground rods.

Sometimes I think the electrical codes are written by plumbers.

No, they are actually written by equipment vendors, engineers and inspectors. Which is why they get more and more complicated/detailed every revision. I knew a fellow engineer that was on one NEC code section committee. It was interestingto hear his stories, to say the least …..
