What else can I help you with?
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.
What size wire for 400 amp distribution panel?
For a distribution panel rated at 400 amps parallel runs of 3/0 conductors will do the job.
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 size wire do you need for 15 amps?
AWG 10.
If you have a circuit breaker box containing 650 amps of circuit breakers it is 3 phase 480 volts what size kva generator do you need?
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
What is the minimum size breaker panel for a home's main service?
50 amps
What is the minimum size breaker panel required for a homes main service?
50 amps
What is the recommended size for the main breaker in a residential electrical panel, specifically for a 125 amp main breaker?
The recommended size for a main breaker in a residential electrical panel with a 125 amp main breaker is typically 150 amps.
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.
How do you find out how big your main breaker box is?
Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.
What is the minimum size breaker panel for a home?
In North America the smallest size breaker found in a home distribution panel is rated at 15 amps
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.
What gauge wire do you need for 12 volts at 4.2 amps in my car for a light H11 Light bulb?
Almost any size wire will handle the 4.2 amps. BUT...as with any wiring, you must look at the over current device to determine the proper size. You need to determine which fuse in the fuse panel protects that circuit and use a wire that is appropriate for that size fuse.
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.
What are the necessary steps for installing a garage sub panel?
To install a garage sub panel, you need to first determine the appropriate size and location for the panel. Then, you will need to run a conduit from the main panel to the garage, install the sub panel, connect the wires, and properly ground the panel. Finally, you will need to test the panel to ensure it is functioning correctly and safely.
How do you tell the difference between 100 amp and a 200 amp box?
You can typically determine the amperage of an electrical panel by looking at the main breaker. A 100 amp panel will have a main breaker rated at 100 amps, while a 200 amp panel will have a main breaker rated at 200 amps. Additionally, the size and number of circuit breaker slots can also be indicators of the amperage rating.
What size breaker would i use to add a 100amp subpanel?
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.
