Any size two pole breaker up to the value of 100 amps. Just make sure that the wire used to connect to the sub panel from the main panel is of a size to correspond to the breaker size. Wire amperages at 90 degrees C are, 30 amp #10, 40 amp #8, 55 amp #6, 95 amps #4,110 amps #3. Also keep in mind to look and see if the sub panel is rated at 100% or 80% load capacity. If it is only 80% load capacity then reduce the amperage rating of the conductors by 80% to obtain their new capacity rating.

What size wire is best to run for a breaker box piggy back from another breaker box?
The wire is sized to the breaker in the main box that is feeding the subpanel. The calculations for the subpanel is based on what devices will use the subpanel and an estimate of duty factors for the devices. An electrician can provide this information, or you can look on-line in the National Electric Code for estimation methods.
How do you read breaker box amps?
The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the breaker that is feeding it. In either case you must look for the manufacturer's label that will have the maximum current the panel can handle, make sure the breaker feeding the panel doesn't exceed this rating.
You want to run power from your home you have a 200 amp in the house to a garage that you recently built you have 110 and 220 outlets The only 220 you plan on running is a small air compressor What?
The voltage for the air compressor is needs to come from a double (two) pole breaker. The size of the breaker needs to be 250% of the full load amps of the compressor. The wire size to the compressor has to be 125% of the full load amps of the compressor.

The formula you are looking for is I = W/E.
What is the breaker size for the 160KVA UPS?
The breaker size for a 160KVA UPS would depend on the specific model and manufacturer specifications. It is recommended to consult the UPS installation manual or contact the manufacturer to determine the correct breaker size for your specific UPS model.

Is the main circuit breaker is a sum of the sub circuit breaker?
Typically yes because that is what makes sense. However, the subpanel could have the same size breaker as long as the panel were rated for that amperage and the wire sizes were appropriate.
What is the recommended wire size for a subpanel installation?
The recommended wire size for a subpanel installation is typically determined by the amperage of the subpanel. It is important to consult the National Electrical Code (NEC) or a qualified electrician to ensure the correct wire size is used for the specific installation.
What is the recommended wire size for a 100A subpanel installation?
The recommended wire size for a 100A subpanel installation is typically 3 AWG copper or 1 AWG aluminum.
What is the recommended wire size for a 50 amp subpanel installation?
The recommended wire size for a 50 amp subpanel installation is typically 6-gauge copper wire.

Can you put a 60amp breaker and a 50amp breaker on a 60amp subpanel just as long as they are not being used at the same time?
You can. Using these size breakers in a 60 amp sub panel might be pushing the limit for breaking the sub panels feeder breaker. The breaker feeding the sub panel will have to be no bigger than 60 amps because of the main bus bar capacity of the sub panel. It would be better to install a 100 amp sub panel and then there would be a bit of a buffer and you will have the ability to add additional small load circuits.

Service entrance wire should be AWG #3 copper.
What is the breaker size for a goulds century pump 1081?
The breaker size for a Goulds Century pump 1081 would depend on the specific model and voltage requirements. Refer to the owner's manual or the nameplate on the pump motor for the correct breaker size recommended by the manufacturer. It is important to match the breaker size with the electrical requirements to ensure safe operation.
