Exclamation furnace breakers burning out

I have a 2 pole 60 amp breaker for my furnace that keeps overheating and starts melting. We have had it replaced twice already, but it seems to start overheating when we run other appliances such as washer, dryer, or dishwasher. An electrician has come out both times to fix it, but obviously there is something else wrong than just a bad breaker. Please help

Is nothing else on the same circuit? If not, it seems as if the other appliances are pulling down the voltage available to the furnace, causing it to draw higher current to maintain power, which in turn overheats the breakers. This can also be caused by a loose connection in the wiring along the way from the breaker box to the furnace.

What brand/model is the panel, and what brand/model is the breaker? Perhaps they are incompatible or flawed in design.

The panel is a Westinghouse B20 1632CG 200 A. MAX Type 1, and the breaker is a Siemens 2 pole 60 amp part # ZZ-7357.

Get the electrcian back and tell him you want the furnace on it's own circuit. (it should be anyway.) Also he can check the load with a amp prob, try to simulate the problem when he comes. A loose connection could be a good cause.
