Fifty amp breakers are generally used to provide power for different appliances. Wiring an outlet for an electric stove isn't the same as wiring standard outlets, because along with the water heater, furnace and central air system, the stove is a high-demand appliance that runs on 240-volt power. Voltage drop can affect performance in undersized wires that are very long. Circuit grounding is required, so all 240-volt receptacles have four slots, but 30-amp receptacles, such as the NEMA 14-30, won't accept a plug from a 40- or 50-amp appliance. I found a few heavy-duty buttons, but was redirected to use a "magnetic door switch" (I think also called a Reed switch). e.g. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor. And the specifications from Sears has Breaker/Copper Wire size (240v) – 30/10.
