I believe that the wires supplying a 30 amp circuit must be at least 10 gauge. If you have 14 or 12 gauge wires going to or from your 15 amp breaker, then drawing 30 amps over it could cause a fire hazard. It's like using those cheapo non-UL certified extension cords to plug a MILLION X-mas lights into (drawing more power than the wires can handle). You also have to make sure this GFI outlet you refered to is rated for 30 amps.



Do not simply swap out breakers. Overloading the wires in the circuit protected by that breaker will cause a fire.

If you need a 30 amp circuit you must run #10 gauge wire.

Can you connect a dryer with a 30A cord and receptacle to a line that has a 50A circuit breaker?

  Answer   Yes and no. You can't put a 30A outlet on a 50A breaker as it will be a fire hazard. You can put a 50A outlet on it safely. Then you can plug the 30A lo

What is a circuit breaker for?

The circuit breaker obviously breaks the circuit but only in an attempt to stop a surge of electricity going through your house and possibly hurting you if you're using an app

If a circuit breaker is a 30A 240V for a dryer and the dryer calls for a 20A do you need to change your breaker?

  No, you're fine.   Answer   Breakers are mainly used to protect the wires (and people), not the appliance. The appliance should have its own overcurrent protect

How many wall outlets can you have in a circuit using a 15A breaker?

One View: In USA: As many as you want. There's no magic number. You have 15A to play with, so you can divide that up however you wish. It all depends on what you intend to

Can you replace a 15 amp circuit breaker with a 20 amp circuit breaker?

The answer is, yes and no. Yes you can physically pull a 15 amp circuit breaker and install a 20 amp circuit breaker into the same slot on nearly all modern electrical distrib

Can you replace a 20 amp circuit breaker with a 25 amp circuit breaker?

Never upgrade the circuit breaker's amperage unless you have first upgraded the circuit. A 20-amp breaker will pop before a 12-AWG wire will melt. A 25-amp breaker cannot be r

How much does it cost to replace fuse box with circuit breaker?

This project is a service upgrade and requires a permit and inspections. In the central United States where I live, you might get it for $800 but don't be surprised if it co

What does a circuit breaker do?

A circuit breaker is a overcurrent device. It prevents fire. An electrical circuit is only as strong as its weakest link. When the voltage rating of a device is exceeded, it

How many switches can you have in a circuit using a 15A breaker?

It is not so much how many switches as it is devices per circuit.    Circuit loading    In Canada the electrical code states that there shall be not more that 12

What is the danger if you replace a 15 amp circuit breaker with a 25 ampere breaker?

If the wire used on the circuit is sized for 15 amps (usually 14 gauge) you run a very serious risk of fire. If the wire used on the circuit is sized for 25 amps (usually 10

Can circuit breaker isolate circuit?

That's just what a circuit-breaker is designed to do - Isolate a circuit from the rest of the system.   Not necessarily. A circuit breaker is a protective device, design
