The size wire you would use for a sub panel box would depend on the square footage of the area it will be servicing.
<<>>
Wire is sized by the amperage of the load, not the square footage of the area it will be servicing. . Depending on what the amperage size of the sub panel that is to be installed, will govern what the conductor size that is to be used.
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.
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 maximum amperage for a subpanel is typically determined by the size of the wire feeding it and the rating of the main panel. It is common for residential subpanels to be 100 or 200 amps, but it can vary depending on the specific installation and electrical code requirements. It's important to consult with a qualified electrician to determine the appropriate ampacity for your subpanel.
To install a subpanel, you will need to first determine the load requirements for the circuits that will be connected to it. Next, choose an appropriate location for the subpanel and install it according to local building codes. Finally, connect the subpanel to the main panel using the appropriate size wires and breakers. It is recommended to consult a licensed electrician for this kind of work.
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.Another AnswerYes, 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.
#6 wire is needed. If placing the subpanel in a garage at a good distance, it is recommended to also install a seperate ground rod .
To add a subpanel to your electrical system, you will need to first determine the appropriate location for the subpanel and ensure it is properly grounded. Next, you will need to run a new circuit from the main panel to the subpanel, making sure to use the correct wire size and type. Finally, you will need to connect the wires to the breakers in the main panel and the subpanel, following all local electrical codes and regulations. It is recommended to consult a licensed electrician for this task to ensure it is done safely and correctly.
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.
The recommended wire size for a 100A subpanel installation is typically 3 AWG copper or 1 AWG aluminum.
The recommended wire size for a 50 amp subpanel installation is typically 6-gauge copper wire.
For a 100 amp subpanel installation, it is recommended to use copper wire with a gauge size of 3 AWG or larger to ensure safe and efficient electrical conductivity.
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.
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.
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.

For new 200 amp services the conduit size should be 3 inch PVC.
