If unaltered, it would by called a "tandem" breaker. Typically used to add new circuits to a full load center.

What's a double breaker 20 amps and 30 amps?
A double breaker is a breaker that has 2 switches on it. One of the switches is 20 amps and the other is 30 amps.
Can you replace a 20 amp circuit breaker with a 25 amp circuit breaker?
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
Need of isolator on both side of circuit breaker?
Before anyone is allowed to work on a high-voltage circuit breaker, it must be tripped, electrically isolated, earthed (grounded), barriers/warning notices put in place, and a permit to work document issued by an engineer to the senior member of the maintenance crew. 'Isolation' means a physical (and visible) break in the conductors between the circuit breaker and any potential source of supply -and this is provided by placing isolator switches on each side of the circuit breaker. Without these isolators, the circuit breaker would remain energized, even though the circuit has been broken by the circuit breaker.
What number wire gauge for a single pole light switch?
In residential wiring applications the most used is 14 gauge wire for light switches as long as the circuit breaker or the fuse is 15A. If your lighting circuit is on a 20A fuse/circuit breaker then you need to use 12 gauge wire
How is a circuit breaker panel wired?
how to connect cables to switches 240 box
Why is it a good thing when a circuit breaker switches off?
Means there is an overload on electricity
What's a double breaker 20 amps and 30 amps?
A double breaker is a breaker that has 2 switches on it. One of the switches is 20 amps and the other is 30 amps.
Can you reverse feed a residential 2-pole circuit breaker?
Yes. This is the way small residential transfer switches connect the generator to the system. The breakers are bidirectional.
What happens when the circuit is complete and the switches are closed?
*Look at the simple circuit illustrated in Figure A-2. What will happen when only switch S1 is closed? Correct Answer= "Nothing will happen-the light bulb won't light up." <<>> If there is a load in the circuit the load will operate. If there is no load in the circuit and it is complete then a short circuit will occur and something in the circuit will burn open. If the circuit is complete and there is a fuse or breaker in the circuit, then the fuse or breaker will open the circuit.
Can you replace a 20 amp circuit breaker with a 25 amp circuit breaker?
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.

Can a Circuit breaker be used as a Switch?
Yes a circuit breaker is a switch but it should not be used as a switch. The continuous turning off and on of a breaker weakens the internal mechanism and reduces the tripping value of the breaker. There is in the marketplace breakers that are designed to be used as switches. These are usually used in large warehouses where the lights are turned on in the morning and shut off at night. Using these specifically designed breakers for switches does not wear out the tripping mechanism or reduce the tripping value. <<>> A circuit breaker can be used as a switch, although in most cases there are less expensive switches you can use.

Is the circuit where is the is the circuit where is the circuit breaker for the?
The circuit breaker for the headlights is intergrated with the headlight switch.

How are Branch circuit protected?
Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker
