Breaker box has no main shutoff.
My breakerbox has no main breaker to kill power to the box. All that occurs is 4 large wires enter the box, 2 to the neutral bus bar 1 to a hot bar that has 15 amp breakers and 1 to a hot bar that has 20 amp breakers. There is an open slot on the 15 amp bar that i wanted to make use of for some can lights in the kitchen. How do you work on a box of this type, as far as i can see there is no way to deaden it.

In your case, VERY carefully.
Is there a main disconnect switch outside somewhere?
You may have to call the power co and have them pull the meter if you need to disconnect it.
An electrician would probably work with it hot. You probably shouldn't.

I live in a quadplex and each building has utility boxes on one end but the only thing in their is cable and garage breakers. My question would be... What voltage do you think is entering the box? I wont touch is hot regardless but I am curious, we have an independent breaker box for our 220 dryer plug.

You have a main disconnect somewhere else.

Hard to say by your description. It is likely a 240 volt panel.
The confusion is where you said "two wires to the neutral bus".
A typical 240 panel would have 2 hots, one neutral and one ground.
PICS??

A "typical" MAIN panel will have two hots and a neutral, and NO ground. This is why I suggested he has a main elsewhere.
Now we see from the pics that this IS a sub-panel.
There DEFINITELY IS a main disconnect somewhere.

Sub, do you own this place or rent?
That looks like a typical old apartment/condo panel.

It's almost as good as the tap for the 30A breaker? A/C or Dryer?

Probably a dryer. Hey, at least they used 3-wire.

Own it. These condos were built in 1973-1975. From what i have seen in the structure, there is no way these where inspected, during construction.

Speaking of that, I would love to get rid of that tap, We run on propane dryers, and have since day one, I do not understand the point of that, there is a dryer receptacle on the other end of that wire.
