Can you use a 30 amp breaker for a stove?

The breaker commonly used for ranges is a 40 amp. This size is used to cover the total wattage of the range. If for some reason all of the top elements and the oven were in use at the same time then the amperage drawn would be just under the trip setting of the breaker. If this same scenario were played out on the range with a 30 amp breaker supplying the power it would trip the breaker.


If a shunt trip occurs does breaker go to off or trip position?

the breaker goes to trip position


If live is kept open could it trip circuit breaker by connecting neutral to ground?

I would think not. However, if live were to come into contact with either the ground, or the neutral or both, this would cause a breaker to trip.


How many circuit breakers would a lightning strike trip?

Generally circuit breaker is not designed to trip off in the event of lightning. The system has lightning arrestors which reroute the lightning effect to earth instantly. If there are no lightning arrestors then the equipment are likely to fail upon a lightning strike.


Can a shunt trip breaker be tripped from to different emergency buttons?

Yes a shunt trip breaker can be activated manually.


How do you detect if a shunt trip breaker is malfunctioning?

The way to detect if a shunt trip breaker is malfunctioning is to manually trip the breaker. The shunt is usually wired through a auxiliary relay. Make sure that before you trip the breaker that the load can be shut off without taking a production line etc. off line. Trip the auxiliary relay using a test jumper to activate the relays coil. The breaker's handle will move to mid throw and the load will disconnect from the supply power. If the breaker trips then it is working properly. If the breaker does not trip trouble shoot the circuitry that is used to trip the breaker. Usual problem is an open circuit.


What would cause a circuit breaker heating element to trip off?

There are two conditions that would cause a breaker to trip off. One is an overload of the circuit and the other is a short circuit on the circuit. The heating element within the breaker is what monitors for circuit overloads.


How much does a shunt trip breaker cost?

The cost of a shunt trip breaker depends on the amperage and number of poles the circuit connected to it needs. The cost of the shunt trip over a conventional breaker is substantially more.


What are the breaker ampere trip ratings?

The ampere frame rating for a circuit breaker designates how the circuit breaker should be configured. It also states the trip unit of the amp.


Does a hot day trip a circuit breaker?

The ambient temperature does have an effect on the tripping point of a breaker. If a breaker is operating at near capacity the additional ambient temperature will lower the breaker trip set point.


Does the power supplied to trip shunt trip breaker have to be applied momentarily or can it latch?

A shunt-trip breaker trips when voltage is applied to the coil. It does not self-reset when the voltage is removed, the breaker must be reset manually. The trip voltage can either latch or be applied momentarily, but must be de-energized before the breaker will reset.


Would a slight rise in the kva cause a 2000 amp gfci breaker to trip?

A circuit breaker trips when the current exceeds the rated trip current. Usually the trip current should be at least 25% more than the maximum expected load current.
