What else can I help you with?
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.
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.
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.
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.
How can I add a subpanel to my electrical system?
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.
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 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.
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 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.
What type of wire should be used for a 100 amp subpanel installation?
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.
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.
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.
