#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 .

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.
You ran power from your house to your shop about a year ago The problem you are having is one of the bus legs in your shop panel box is not hot so every other 20 amp breaker is not hot on that leg?
Sounds as though you only ran a 110 volt power supply to your new shop subpanel. You need to supply 220V with a neutral and ground from your main panel to your subpanel. The 220 supply needs to come from a two pole 220V circuit breaker in your main panel. (example 50 or 100 Amp) Then, most importantly, you must use the correct size wire to carry the current. That is the wire must be sized correctly to the 220V breaker. The neutral must also be the same size as the conductors. Once you determine how much power you need in your shop, size the supply 220v circuit breaker and wire accordingly. Check with your local building department if you are unsure or what size wire to use with what size breaker or refer to Table 310-16 in the National Electric Code. In Australia domestic power is 240v So you have run single phase power to a three phase switchboard. To get power to those breakers you must hook the active to the busbar connected to those circuit breakers.
What wire size do you need for a 125 amp panel with a 100 amp main breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
Do you need a main disconnect on the feeder wires running to a detached garage running from the box in the house?
Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.
What gauge wire to use for direct burial for a garage that is 400 feet from your house?
Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.
What is the maximum amps for a sub panel?
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.
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 size wire should be used for ground wire from main to subpanel?
The size of the ground wire should be based on the amperage of the subpanel. A common recommendation is to use a copper wire of at least #8 gauge for a 100-amp subpanel, and a #6 gauge for a 200-amp subpanel. Always consult local electrical codes and regulations for specific requirements in your area.
Can you run an additional breaker panel parallel to the existing one?
It is generally not recommended to run an additional breaker panel in parallel with an existing one. This can create potential safety hazards, overload circuits, and violate electrical codes. It is best to consult with a licensed electrician to properly assess the situation and determine the best course of action.
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?
You will need to install a subpanel in the garage with a capacity of at least 60 amps. This subpanel can be fed from the main panel in the house using appropriate gauge wires. Ensure that the 220V outlet for the air compressor is connected to the subpanel. The 110V outlets can be connected to the subpanel as well, distributing power as needed.
How do you read breaker box amps?
To determine the amps of a breaker box, look at the main breaker or label inside the panel. The number on the main breaker indicates the maximum amperage that the breaker box can handle. Make sure not to exceed this amperage to prevent electrical hazards.
What size subpanel do you need for 6 20A circuits?
The size of the sub-panel is dependant upon the total load amps of the devices you want to connect. Take into account if more that one device will be or could be running at one time.
Installing a 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.
200 amp main and would like to add another 100 amp service in another room how can you do this?
To add another 100 amp service in another room, you would need to install a subpanel. This involves running a new electrical line from the main panel to the new location, installing the subpanel, and connecting the new circuits to it. It's important to ensure that the overall load on the main panel does not exceed its capacity with the addition of the new subpanel. Consulting a licensed electrician is recommended to ensure the work is done safely and up to code.
How do you install a 50A sub panel to a 100A box?
To install a 50A sub-panel to a 100A main panel, you will need to first ensure that the main panel has enough capacity to support the additional sub-panel. Next, you will need to run appropriate gauge wires from the main panel to the sub-panel, and install a double-pole 50A breaker in the main panel to feed the sub-panel. Finally, connect the wires to the appropriate terminals in the sub-panel and ensure everything is properly grounded. It's recommended to consult a licensed electrician for safety and compliance with local electrical codes.
What size wire is best to run for a breaker box piggy back from another breaker box?
The size of the wire depends on the amperage of the circuit it will be serving. Consult the National Electrical Code or a licensed electrician to determine the appropriate wire size for your specific situation. It is crucial to use the correct wire size to ensure safety and proper functionality.
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.
