I too agree it sounds like an open neutral.. As for the single 50 amp breaker...
They make a breaker that has a single lever, but is in fact a double breaker,, I know I had the 150 amp version of it in my house. Like all breakers it comes in assorted sizes (Ever see an 800 amp breaker,,, I have.. It too was a single lever 240 volt dual breaker).
To diagnose .. One assumes you have two AC/s.. TURN OFF everythign, in fact turn off the circuit breakers that feed televisions and other electronic devices including your converter.
Leave on only the following
General outlets with nothing plugged into them (NOTE there is another way to do this) you need two such circuits, one on each side of the neutral. and at least ONE of the two air conditioners.
now plug volt meters into both outlets, ANALOG meters work best for this.
Turn on the AC and watch the meters
One drops a volt or 3, other either goes with it or stays static, GOOD
One goes down other goes UP seriously (like more than 10 volts) open neutral.
How do I know this: Happened on the sticks and bricks and that is EXACTLY how I diagnosed it.
