The electrical terminology for this type of breaker is a tandem breaker. It is where two breakers circuits can be in the same one breaker slot in a distribution panel. On this type of breaker there will be two output for a circuit value of what ever the breaker is rated for.

That depends on what you're calling "piggy back".

Most manufacturers provide a breaker category that allow two circuit breakers to fit into what would normally be the space for one.

Breakers should NEVER be connected such that the output is tied together to provide for greater current output, so if that's your definition of piggy back, the answer is "no".

Can you install 2 conducters in a cuttler hammer 1 pole 20 amp breaker?

the answer is no period. You will only make this circuit breaker trip more often. you will need to install another 20 amp circuit or install what is called a piggy back circuit breaker. you can may find this at Lowes or Home Depot or better yet take a circuit breaker out of the electrical panel and go to a electrical distributor.


Is square d breakers compatible with ge breakers?

Breakers are build to snap onto a buss bar in a breaker panel. If they look the same on the back end then they will likely work. If not do not try to force a fit. To add a little more to this: 1st of all it depends on what kind of Square D you are talking about. Square D Homline breakers will fit in a GE panel but GE breakers will not fit into a Homeline panel in my experience. Square D QO is not compatible with either.


When the test button is pressed on a gfci outlet it sparks and trips two breakers in the main panel What could be the problem?

The test button should only trip the GFCI. The fact that it is tripping two breakers indicates that somehow both breakers are feeding your GFCI circuit. I have seen this when there was a wiring error and two circuits were joined in an outlet that was connected to a breaker and through the GFCI outlet. To troubleshoot determine which outlets are effected when both breakers are off. Pull outlet from box and if there are two feeds remove one from outlet and run a toner on wire left on outlet to panel and one off outlet to panel. The GFCI could block the toner so if one side of the outlet does not tone back to panel check at GFCI. There must be two paths to your electric panel for the two breakers to trip and the GFCI may be faulty as well. Another way to check is to have the GFCI reset and both breakers on. Check each outlet that you have identified as being on GFCI noting that they can be in different rooms. With all outlets working turn off one of the tripped breakers. See if any outlets so off. If not turn off the other breaker and turn on the first breaker. If power is still present then the outlets are being fed by both breakers.


How do you find a triped circuit?

Check the circuit panel / breaker box. The tripped breaker should be partway between 'OFF' and 'ON'. If nothing else, turn the breakers off then on, one at a time and when the tripped breaker is reset, the circuit should be live again. Also check GFI outlets. If one is in fault condition, it will need to be reset. If the tripped GFI outlet is protecting other outlets, they will come back when the tripped GFI is reset. These sockets seem to hide in many cases... Behind microwave ovens for example or refrigerators.


Any problems with shared neutral for for 4 15 amp breakers each on dedicated circuits?

Yes. If it a residential home then you can only have two breakers per neutral and they need to be on opposite legs of your panel. If it is a commercial 3phase panel then you can only put 3 breakers on a shared neutral. Here's why. In your panel assuming its residential you have two power wires and one neutral and these power wires are called legs. If you attach two breakers on the same leg that is across from each other on opposite sides of the panel or skipping a space between breakers on the same side at 15A apiece you return on the neutral will not be balanced and you will have the possibility of 30A coming back to your panel on the neutral which will fry a 14 Awg or even 12 Awg for that matter and cause a fire. Now if the breakers are in tandem that is they have the breaker tie that connects two breakers together they will be on separate legs and then only will your breakers/circuits be balanced and it will be safe to share a neutral on. If two tandem breakers are connected to a single neutral and they are all 15A breakers your return would be 30A again because although your tandem breakers are balanced now you have two tandem breakers returning a potential 15A per two breakers and that adds up to 30A. The next problem you have is when you share a neutral as per the National Electric Code if one breaker trips the other breaker also sharing that neutral must trip so that when the power is off any current that could possibly return through the neutral wire will be cut off. So now this creates another problem with 4 breakers sharing the same neutral is now there is no way to get all four to trip at the same time if there was a ground fault (a short) or an overload. and someone could get nailed by any current coming back on the shared neutral. All the same applies for 3phase except there are 3 power wires and you can use 3 breakers with a 3 breaker tie instead of just two. You either need to run one neutral per tandem breaker or four neutrals for four circuits/breakers. Tandem breakers controlling two separate circuits are a pain because when one breaker trips they trip the other circuit also. Tandems are mostly used for two circuits going to the same appliance so that no power on either leg reaches the appliance when it needs to be off.

What is a branching circuit?

Each of the circuit breakers in the service panel controls electricity on a branch circuit. A branch circuit is typically a loop of wire that runs from the service panel, out to receptacles, light fixtures, appliances, etc. and back again.

What is the place in the home that contains the circuit breakers?

The ciruit breaker box. This is usually mounted near the main power source in the home. Try the basement, the back porch, or near the kitchen. If all else fails, go outside and look where the power meter is. The breaker box should be nearby inside the home. In many homes the electrical panel is in the basement. In homes that do not have basements the electrical panel is placed in the garage.


Do Ceiling lights in bedrooms have to be on a arc fault protected circuit breaker?

No, bedroom lights fixtures do not have to be on arc fault breakers. In fact it is better if they are not. The neutral should return straight back to the distribution panel, for the arc fault circuit that the neutral is in. In some jurisdictions an electrical code amendment requires that the cable fed from arc fault breakers be identified with a blue outer sheath.

What are electric fuzes?

In most places fuzes have now been replaced by circuit breakers. They prevent circuits from becoming overloaded and starting fires. With modern circuit breakers, you just have to flip the switch to turn the electricity back on. Old fuses were like the base of a light bulb, and a filiment would burn out if it was overloaded. Back then, you had to replace a blown fuze with a new one to restore electricity.

What is difference between shunt trip and ground fault circuit breaker?

Ground fault breakers monitor the current on the neutral wire flowing back to the neutral bar, a 4 to 6mA difference will trip the breaker, Shunt trip breakers on the other hand can be tripped remotely from some other type of switch or location. In industrial applications it is used to shut power off in an emergency situation, when access to an electrical panel may denied.

How does one give a piggy back ride?

There are many ways to give a piggy back ride correctly. One must make sure that one has a very strong back in order to give a piggy back right and then one must put another one top of his back.
