Canada and US - Standard size breaker in home panel is 40 amps for stove. If not standard range open Discuss Question page.

No, because if you switch a 50-amp load on, it will blow a 40-amp circuit breaker if the load exceeds 40 amps, which is likely.

You need to look on the manufacturer's specification plate on the unit for the amperage and voltage.

Depends on the manufacture of the water furnace. Look at the data sheet or data plate on the furnace of contact the manufacture.

A circuit breaker shuts off the power to an electrical circuit when it detects too much current flow. As electricity moves through wiring, an electromagnetic field develops around the wire. Electromagnetic breakers capitalize on this field production by using electromagnets. The current that moves through the breaker charges the electromagnet and as the current increases the magnetic pull also increases. If the current exceeds the limit the breaker is designed to handle, the magnetic pull becomes strong enough to pull the contact plate away from the stationary plate. This breaks the circuit and is referred to as "tripping the breaker.

A surge protector on the other hand prevents a voltager higher than the normal voltage from damaging electical devices. It does not shut off the power as a circuit breaker or fuse does.
