Can you turn off an appliance at the breaker box to protect against lightning?

Yes and no. This answer depends mostly on the path that lightning will take through your home when it hits. Probably the best way to explain this is that your electrical wiring in your home is like a big net, all interconnected by your electrical panel. When everything is connected the breakers can act as barriers to electrical surges, but they may not be totally effective as they usually need a fraction of a second to pop. Arc fault protected and ground fault protected breakers are faster and more sensitive so they will protect circuits better but they are not recommended for all of your appliances. The good news is that electricity takes the path of least resistance so once it hits your panel, if its grounded properly (and it should be), the electricity will go to your ground, away from the house. If the electricity hits a circuit of your house that is connected to your appliance, it may damage your appliance. The best thing is for your appliance to REMAIN connected to the panel so that the grounding can direct the path of the electricity away from your appliance. On the other hand, if it hits another part of the house and the appliance is isolated, it could protect it even more just by not being hooked to the net at the time. In the end, stay away from your panel during a storm. You will be safer and your insurance company will ask fewer questions. They may not cover your loss if you turned the breaker off and damage occurred.

Installing a 120volt appliance what breaker is needed at the electric box?
For a 120-volt appliance, a single-pole breaker with a rating suitable for the appliance's power requirements should be installed in the electric box. The amperage rating of the breaker should match the current draw of the appliance to ensure proper protection and operation. It is important to consult with a qualified electrician to determine the appropriate breaker size for your specific appliance.
What happens when you plug a 30 amp appliance into a 50 amp breaker?
If you plug a 30 amp appliance into a 50 amp breaker, the breaker will still function to protect the circuit from overheating due to excess current. However, the appliance may not draw enough current to trip the breaker in case of a fault, potentially causing damage to the appliance. It is generally recommended to match the amperage of the appliance to the appropriate breaker size.
Can you hook up a two pole 20 amp breaker to a 30 amp outlet for a dryer?
No, that is not safe or appropriate. The breaker and outlet must be the same amperage to protect the electrical circuit and appliance. Using a 20 amp breaker with a 30 amp outlet could cause damage to the appliance, create a fire hazard, and violate electrical codes.
A small appliance circuit will be protected by a circuit breaker rated at?
A small appliance circuit will be protected by a circuit breaker rated at 15 or 20 amps. This is to ensure that the circuit can safely handle the electrical load of the small appliances without overloading.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.

Does lightning protect?
No lightning cant protect it only destroys.
Can you use 70amp breaker for 40amp device?
No, you should not use a 70 amp breaker for a 40 amp device. The breaker amperage should be matched to the device's requirements to ensure proper protection. Using a breaker with a higher amperage rating than the device can lead to potential safety hazards like overheating and electrical fires.
What meaning mcb?
MCB, Miniature Circuit Breaker is electric switch which is used to protect against short circuits

A small appliance circuit will be protected by a circuit breaker rated at 15 or 20 amps. This is to ensure that the circuit can safely handle the electrical load of the small appliances without overloading.
Can you add a larger breaker to run a second appliance on a circuit?
No, absolutely not. The breaker is there to protect the wiring within that circuit from overheating and catching on fire. If you add a larger breaker and the wire stays the same the wire is no longer protected by the correct amp breaker. You could cause a fire. The breaker must match the size wire being used. Do this and you risk burning your home to the ground and possibly killing your family.
How do fuses and circuit breaker protect your home against electrical fire?
