No, a two pole GFCI breaker must be wired to both hot wires of a circuit in order to function properly. Using only one side will not provide the necessary ground fault protection.
A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
A 220 VAC breaker can be single pole or double pole depending on the application. For standard 220 VAC circuits like most household appliances, a double pole breaker is typically used. However, in certain situations where only one hot wire is needed, a single pole breaker can be used for 220 VAC circuits.
First, check the circuit breakers; make sure they are all ON. Find out if any other outlets on the same breaker are working; it's always possible that a breaker is faulty. If the breaker is on and everything else on the circuit is working, it could be as simple as a poor connection inside the outlet. Also even though the outlet is not a GFCI, it may be fed from a GFCI outlet. Check near by outlets to see if any are GFCI and are tripped.
GFCI receptacles are extremely sensitive, there are any number of reasons this may not be working for you. The first thing you can do is to make sure that the wire feeding your 2 other outlets off of the outside GFCI are connected to the line side of the device. There are 2 sides to any GFCI: the "line" and the "load" side. The line connections are typically at the bottom, and the load at the top.The load side is protecting all the downstream receptacles on the circuit. Be sure you have the blacks ("hot" or "line") and whites (neutrals) all on the correct side. Any receptacles downstream don't need to be GFCIs because they will automatically be protected if connected to the load side of the first GFCI.If you want to use GFCIS for the two new receptacles then you should make sure they are both connected to the line side BEFORE the outside GFCI so they will work independently of the outside one.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
You need a GFCI outlet at any location that is within 6' of a water source. You also need a GFCI outlet in a room with a concrete floor, any garage, and any location outside the home or under the home in the crawl space. A GFCI outlet protects you from electrical shock near water or moisture. You can protect more than one outlet with 1 GFCI outlet. Connect the incoming power to the LINE side of the GFCI outlet and all the other outlets getting power from that outlet to the LOAD side of the GFCI outlet. That way they will all be protected by 1 GFCI. A GFCI breaker is used to protect an entire circuit and not just individual receptacles. It is often cheaper to use GFCI receptacles than a breaker, especially if "piggy-backed" such as described above. It is also more convenient to reset a GFCI receptacle than to reset a breaker. But your question is "why." From this I suspect you may be misunderstanding the difference between a breaker and GFCI protection. To keep things simple let me say that a GFCI does not work on the same principles as a standard breaker. It provides a much safer protection than a standard breaker. Even with a ground you need GFCI protection as listed above.
No, only one GFCI per circuit.
A tandem GFCI breaker is designed to provide ground fault protection for multiple circuits in a panel. It differs from a standard GFCI breaker by being able to protect two separate circuits instead of just one. This allows for more efficient use of space in the panel while still providing the same level of electrical protection.
A single pole breaker controls one wire and is used for 120-volt circuits, while a double pole breaker controls two wires and is used for 240-volt circuits.
A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.
A single pole breaker controls one hot wire and is used for 120-volt circuits, while a double pole breaker controls two hot wires and is used for 240-volt circuits.
A double pole breaker controls two hot wires and provides 240 volts of power, while a single pole breaker controls one hot wire and provides 120 volts of power.
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
TPN means three pole with one pole neutral connected.
A 220 VAC breaker can be single pole or double pole depending on the application. For standard 220 VAC circuits like most household appliances, a double pole breaker is typically used. However, in certain situations where only one hot wire is needed, a single pole breaker can be used for 220 VAC circuits.
