It is based on the amperage of the service panel in a single phase home panel useing copper wire use.
100 amp use AWG # 3 copper
200 amp use AWG # 3/0 copper
Feeder sizes are based on the amperage of the connected load. Once that is found there are tables in the electrical code book that state what the wire size is for that particular amperage.

The recommended size for a main breaker in a residential electrical panel with a 125 amp main breaker is typically 150 amps.

Definition from the National Electrical Code Article 100:Feeder. All circuit conductors between the service equipment, the source of a separately derived system, or other power supply and the final branch-circuit overcurrent device.Branch Circuit. The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s).
For connecting a 220 junction box to a main electrical panel, it is recommended to use a 1-inch diameter PVC conduit. This size and type of conduit will provide sufficient space for the wires and ensure proper electrical connections.
Yes. Feeder fish just like all goldfish grow depending on the size of their environment. I once had a feeder fish in a 50 gallon tank that was 8/9 inches long when it passed at the age of 7.
They vary is size. Most of mine will hold a quart.
For a 100 amp service, a common feeder wire size would be 2 AWG (American Wire Gauge) copper or 1/0 AWG aluminum. These sizes are appropriate for handling the current capacity needed for a 100 amp electrical service. It is important to consult with a licensed electrician or local building code requirements to ensure the proper wire size for your specific installation.
The main fuses protect the feeder lines from the electric company's feed to the main panel for the maximum ampacity rating of the wire. So depending on the size of the incoming tails nothing is gained by reducing the main supplier's cut-out fuse rating to 60A or 40A.
To properly wire a sub panel in a residential electrical system, you need to connect the feeder wires from the main panel to the lugs in the sub panel. Make sure to follow the manufacturer's instructions and local electrical codes. It's important to use the correct size and type of wires, install a grounding rod, and properly bond the neutral and ground bars in the sub panel. It's recommended to hire a licensed electrician for this task to ensure safety and compliance with regulations.
To wire a sub panel, you need to connect the feeder wires from the main panel to the lugs in the sub panel. Make sure to follow the proper wiring diagram and use the correct size wires for the amperage of the sub panel. It's important to turn off the power before starting and to follow all local electrical codes and regulations.
