I was trying to disconnect a 220 50 amp breaker to replace with a 30 amp, changing function for the breaker.
When I disconnected the white wire from the neutral bar it jumps to 120 volts on the bar and 220 throughout my building shutting everything down.
When I reconnected the white white (the two hot leads already disconnected)and service was back to normal.
Tried disconnecting the white wire at the receptacle with the same results.

be very careful, the neutral on your breaker may be conducting all neutral current to ground through the ground ofwhatever 's connected to that breaker. if you are not careful that current will flow through you or something else.
it's probably time for a licenced electrician l to take a look at your circuit breaker panel
