No, you cannot use one in place of the other.
Replacement for American Switch single pole 15 amp circuit breaker
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
The 240 volt receptacle has to have an amperage rating. It is this rating that governs the wire size and breaker size to feed the circuit. The new two pole breaker will be inserted in the 100 amp distribution if space is available and connected to the new wiring that terminates at the new receptacle.
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
The appropriate double pole 30 amp breaker to use for a dryer installation is a 30 amp double pole circuit breaker.
Yes.
The purpose of a 50 amp 2 pole breaker in an electrical circuit is to protect the circuit from overloading by disconnecting the power when the current exceeds 50 amps.
Remove the 30 amp double pole breaker and install at least one single pole 15 amp breaker. It is best if the other slot is not left open so if you have another single pole breaker of any size install it in the 2nd spot so it isn't open when you replace the cover on the panel. For your 15 amp circuit you need #14 gauge copper wire or larger with a hot, neutral, and ground. Your 30 amp circuit was probably wired with #10 gauge conductors. These will probably work on your 15 amp circuit but it may be difficult to connect #10 conductors to devices.
The purpose of a 30 amp double pole breaker in an electrical circuit is to protect the circuit from overloading by shutting off the power if the current exceeds 30 amps.
The purpose of a 50 amp single pole breaker in an electrical circuit is to protect the circuit from overloading by interrupting the flow of electricity if the current exceeds 50 amps.
The purpose of a 2 pole 20 amp breaker in an electrical circuit is to protect the circuit from overloading and overheating by interrupting the flow of electricity when the current exceeds 20 amps.
The purpose of a 2 pole 50 amp breaker in an electrical circuit is to protect the circuit from overloading and overheating by interrupting the flow of electricity when the current exceeds 50 amps.
The purpose of a 30 amp 2 pole breaker in an electrical circuit is to protect the circuit from overloading and overheating by interrupting the flow of electricity when the current exceeds 30 amps.
A double pole 60 amp breaker in an electrical circuit is used to protect the circuit from overloading and short circuits by disconnecting power when the current exceeds 60 amps.
The purpose of a single pole 50 amp breaker in an electrical circuit is to protect the circuit from overloading and overheating by interrupting the flow of electricity when the current exceeds 50 amps.
