It is not in parallel. You put a breaker in existing panel and use that to feed the subpanel. The Amperage of this subfeed breaker should match the rating of the new panel. For example a 100A breaker might be typical. Remember that ground and neutral are only "bonded" at the main panel. Usually a subpanel has a means to separate the neutral and ground in a subpanel. Be careful since everything about doing this is dangerous.

Yes, you can have two breaker panels in parallel. If you had a 100 amp panel on a 200 amp service (or increase the size of the service, check with your power company on the size of your service, you could add a second 100 amp panel in parallel with the first. You can have up to 6 disconnects per service, but they must be located adjacent to each other or in the same enclosure. So either install the second panel beside the first or a 100 amp disconnect beside the first panel and feed out of the disconnect to the new panel located where you need it.
The provisioning of the breakers in a panel has a physical limitation regarding how many breakers will fit and a load calculation based on what devices the panel has to support. Your question really applies to both types of breakers. There are rules of thumb for sizing and populating the panel. This information is in the National Electric Code. If you have an existing panel and a new application requiring additional breakers for 220 Volt applications, the current draw in panel can be measured by an electrician and you will know what additional load you can support. If breakers fit physically in the panel, but connected devices exceed the total current capacity you will trip the main panel breaker. At this point you would need to get an electrician involved.
If you don't have a Westinghouse breaker, you should use a breaker that is compatible with your electrical panel. Consult the panel's specifications or a qualified electrician to determine the appropriate replacement breaker for your specific panel. Using an incompatible breaker can be dangerous and may violate electrical codes.
That depends on the manufacturer of the breaker panel. Some manufacturers sell dual breakers that can be plugged in where one of your single breakers are now. You can also do an audit of current panel, ideally by a qualified electrician. You may have unused or underused circuits. For example if you had two 15A circuits that had a maximum aggregate usage of 5A, you could splice those circuits external to the main panel in a junction box (and wire to one breaker) and use the leftover breaker for your new circuit. In any solution you need to ensure that your panel service is compatible with the loads in your house. In some cases you may need to increase the size of your panel. Consult an electrician and ask for a free estimate.
Answer for USA, Canada and countries running a 60 Hz supply service.There are no dangers to using a pigtail surge protector. The installation of the protector must be done correctly though. The pigtails must not be installed on an existing circuit that has an existing load on it unless the breaker is approved for more than one circuit load on it. The protector must use a new two pole breaker with no additional load on it except the surge protector. This is the correct procedure to connect a pigtail surge protector to a distribution panel board.
Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.
To change a 100 amp breaker in an existing box, first ensure your safety by turning off the main power supply to the panel. Remove the panel cover and carefully disconnect the wires from the old breaker, noting their positions. Install the new breaker by connecting the wires to it in the same configuration, then securely snap the breaker back into the panel. Finally, replace the panel cover and turn the main power back on, checking that the new breaker functions correctly.
To replace a 200 amp main breaker in a residential electrical panel, follow these steps: Turn off the main power supply to the panel. Remove the panel cover to access the breaker. Disconnect the wires connected to the existing breaker. Unscrew and remove the old breaker. Install the new 200 amp main breaker in the same position. Connect the wires to the new breaker. Secure the breaker in place and replace the panel cover. Turn the main power supply back on and test the new breaker.
To install a GFCI breaker, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the circuit breaker you want to replace with the GFCI breaker. Disconnect the wires from the existing breaker and connect them to the new GFCI breaker according to the manufacturer's instructions. Secure the GFCI breaker in place and replace the panel cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
1) If you are tripping the main breaker and you do not have an electrical fault in the home. 2) If you are installing additional circuits or appliances and you expect to exceed 80% of the load capacity of the existing service panel.
To install a GFCI breaker in a circuit, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the circuit breaker that needs to be replaced with the GFCI breaker. Disconnect the wires from the existing breaker and connect them to the new GFCI breaker according to the manufacturer's instructions. Secure the GFCI breaker in place and replace the panel cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
The panel and breaker have to be of the same manufacturer. This way the breaker will fit into the panel. If the panel has a push in bus bar, the breaker must also be the type to accept the bus bar. If the bus bars in the panel are of the bolt in type then the breaker also has to be a bolt in breaker.
The purpose of a sub panel with a main breaker in an electrical system is to provide a secondary distribution point for electricity in a building, allowing for additional circuits to be added without overloading the main panel. The main breaker in the sub panel serves as a disconnect switch for the circuits connected to it, providing safety and control over the flow of electricity.
To properly add a breaker to a panel, first turn off the main power switch. Remove the panel cover and identify a free slot for the new breaker. Connect the breaker to the panel's bus bar and then connect the circuit wire to the breaker. Secure the breaker in place and replace the panel cover. Finally, turn the main power switch back on.
To add a breaker to a panel, follow these steps: Turn off the main power supply to the panel. Remove the panel cover. Identify a free slot in the panel for the new breaker. Insert the new breaker into the slot and secure it in place. Connect the wires to the new breaker according to the manufacturer's instructions. Replace the panel cover and turn the power back on.
You can reduce the breaker size because that limits the current that can reach the main panel. There is no safety issue other than the significant danger in an unskilled person changing out a main breaker.
To install a 50 amp breaker in an electrical panel, first turn off the power to the panel. Remove the panel cover and locate an open slot for the breaker. Insert the breaker into the slot and connect the wires to the breaker terminals. Make sure the wires are securely attached and tighten the screws. Finally, replace the panel cover and turn the power back on to test the breaker.
It is inserting a breaker into a service panel.
