Answers for the US:
A true 2-pole breaker (with a single operating handle) is designed such that an overload on either pole will cause a trip, disconnecting both poles. This type of breaker must be used to supply a 240 volt appliance.
Breakers with separate operating handles or separate breakers should never be used to supply 240 volt appliances, because a trip on one of the breakers may not trip the other, leaving the circuit energized - a very dangerous condition. This is absolutely illegal in the US.
Another view:
They make both types. If a 220-240 Volt device is connected to a 2-pole breaker it may be using both 110-120 V to operate. For example an electric stove may have 220-240 V across the heating elements and use 110-120 V for the clock. Hence, if only one pole tripped the stove may appear to be on because the clock is working, but the 220-240 functions won't work. If you find this condition, have it immediately corrected, because it is both unsafe and illegal.

What is a circuit breaker with 2 switches?
A circuit breaker with 2 switches typically refers to a double-pole circuit breaker. This type of circuit breaker has two separate switches that simultaneously disconnect both the positive and negative wires of a circuit, providing complete electrical isolation. It is commonly used for appliances or devices that require a dedicated electrical connection.
How are the earth and a bar magnet similar?
Both the Earth and a bar magnet have magnetic fields that extend outwards from their poles. They both have a north and south pole orientation, and like poles repel while opposite poles attract. Additionally, they both have the ability to interact with other magnetic materials in their vicinity.
Can you survive in both the north and south poles?
No.
One of the 120 volt legs in the main breaker has lost power?
If one of the 120-volt legs in the main breaker has lost power, it can cause issues with appliances and devices operating on that circuit. This can lead to uneven power distribution in your electrical system and may require troubleshooting by a qualified electrician to identify and resolve the underlying cause of the power loss.
Which latitudes correspond to the North and South poles?
You can find both poles at 90 degrees, N and S, respectively.
What is the purpose of a 50 amp two pole breaker in an electrical circuit?
The purpose of a 50 amp two pole breaker in an electrical circuit is to protect the circuit from overloading and overheating by disconnecting power when the current exceeds 50 amps on both poles simultaneously.
Can 50 Amp breaker replace 45 Amp breaker?
Both a 45 amp and 50 amp breaker would require 6 AWG wire. So if you have 6 AWG wire and any devices like an outlet are rated at 50 amps or greater you are okay.
Why would a 30A-250V outlet still have power with breaker off?
It sounds like the breaker is unserviceable. Seeing as it supplies 240 volt outlet it must be a two pole breaker. If it is a single handle two pole breaker then one pole set inside the breaker is not disconnecting one of the lines. If it is supplied from two single pole breakers that has a common tie, the common tie might be loose and does not shut off both poles when thrown to the off position. If there is no common tie then both breakers must be turned off to interrupt the 240 volt supply.
What is the purpose of a Square D 30 amp double pole breaker in an electrical circuit?
The purpose of a Square D 30 amp double pole breaker in an electrical circuit is to protect the circuit from overloading and overheating by disconnecting power when the current exceeds 30 amps on both poles simultaneously.
100amp breaker is 100amp on both phases or one phase?
A two pole breaker protects both L1 and L2 legs. An over current on either leg will trip the breaker.
What is a double pole breaker and how does it differ from a single pole breaker in terms of electrical circuit protection?
A double pole breaker is a type of circuit breaker that controls two separate electrical circuits at the same time. It differs from a single pole breaker in that it can disconnect both the hot and neutral wires in a circuit, providing greater protection against overloads and short circuits. This makes it suitable for larger appliances or circuits that require more power.
how do you make a magnet with north poles at both ends and south poles in the middle?
You can’t.

How many degrees latitude is the equator from the poles?
The equator is 90 degrees of latitude from both poles.
Why are hollow electric poles preffered over solid poles?
They both weigh and cost less.
