I'm installing a tankless water heater and it calls for 2 2-pole 60 amp breakers. The water heater currently installed uses one 2-pole breaker. I am out of space in the box so I'll have to either find a 1/2 size 60 amp breaker (I'm not seeing any online, so I assume 50 amp is the biggest 1/2 size breaker on the market), get a bigger box or add on a smaller box dedicated for the water heater. The question is, is there a 1/2 size 60 amp breaker out there? The other question is could I get by with 2 50 amp breakers or would they just trip every time the heater kicked on?

Just add another box and quit fricking around. If the unit calls for 60 amp why would you consider installing 50's?

Use what it calls for. No you cannot run a 120v single pole feed to a 240v appliance. Install a subpanel.

could I get by

I didn't really ask this.
they make skinny 2-pole breakers up to 50 amps

You want to make sure also your service panel can handle another 60. It sounds like your panel must already be loaded down. Do you have any single poles in there you no longer use?

how about stacking some of the smaller breakers? Like the 20's or 15's if you have them? It is not possible to do what you are asking, as 220 doesn't work that way

You probably need to have an electrician look at it just to make sure your current panel will support the load. You might have to upgrade.

It's not necessary to subfeed another panel. I assume you have several single pole 20A circuits in this panel. I'd also assume that most these, if not all, are laid down on 1" breakers.
If that is the case then you can simply replace four 1" 20A single-pole breakers with four 1/2" 20A single pole breakers, thus freeing up two 1" spaces in your panel for the new 60A 2-pole breaker.

This, BUT, you really need to know how much amps you are already pulling, add the other two 60 amps. Good chances your main breaker is 200 amps. If that is the case, you might be looking at a new service all together.

Even so he still needs to make sure his service can handle another 55 amps or so.

already done.
The panel was installed when this was a one-room hunting camp. Now it's a 5-room hunting cabin.
I will check to see if the box can support the additional amperage, but I won't be adding 2x60 because I'm also subtracting the amperage of current hot water heater.
So nobody knows is a skinny 60A breaker exists?

I've never seen one but you could call a electrical supply house and ask them. They could tell you

What brand is the panel?
Posted on 9/14/16 at 3:02 pm to eljusterina
GE. 200 amp max.
The water heater is on a 2-pole 30 amp breaker. the new one needs 2 60 amp breakers. Am I increasing the pull by 30 amps or 90 amps?

Notoco in BR will have the breakers you are looking for.
What's the ampacity of the ge panel? If it's 200 amp I would not worry about over load.
