How do I choose the right circuit breaker for my home?
Plan for any possibility for extra loads as well. This will be essential to select the right amperage size and how many circuit breaker spaces you will need. GFCI breakers take up a full space or two depending on what your powering.
How long is the circuit from main panel to detached garage?
Yes it is about 125 feet from the main panel box to the sub panel box on the detached garage. Half the circuit length in this case is 125ft... total circuit length is 250 ft (out and back). Not sure why the calculator says to use 1/2 length of the circuit - when I do I getting differing results... acceptable results for #6 methinks.

Without a bit more detail, it's not possible to give an accurate answer. As a general guideline, you'd use 12 AWG copper conductors with a 20 ampere breaker, and 14 AWG copper conductors with a 15 ampere breaker. Since the receptacles are in a garage, they'll have to be GFCI protected.
Is 100 amp service enough for garage?
You will need #3 copper or #1 aluminum if you want to protect it with a 100 amp breaker. You can use whatever size panel you want at the garage but if you want to fully utilize it you should feed it with proper sized wire and protect that with a properly sized breaker.
Does a detached garage need a subpanel?
This depends on how much power you typically use when working in your garage. If you are running welders and compressors that require high voltage then you will need a 100-amp sub panel. If you are just doing small jobs then you will only need a 50- to 60-amp sub panel.

What size wire do I need to run from house to garage?
In general, you need 10-gauge wire for a 30-amp subpanel, 8-gauge for a 40-amp one and 6-gauge for a 50-amp subpanel. If you need a 100-amp subpanel, you'll be running beefy 3- or 4-gauge cable with a 6-gauge ground wire. Voltage drop becomes an issue over distances in excess of 100 to 150 feet depending on cable size.
How many receptacles can be on a 20 amp circuit?
The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.

What does the NEC require for a detached garage?
At least one 120-volt, 20-ampere branch circuit shall be installed to supply receptacle outlets in attached garages and in detached garages with electric power. Code Change Summary: A new code section was added to require a 20 amp circuit for a dwelling unit garage.
How many outlets can be on a 20 amp circuit in a garage?
One rule of thumb is to assign a maximum draw of 1.5 amps to each receptacle, which allows for 10 receptacles on a 20-amp circuit.
What wire do I need to run a garage?
So, that said, I'd use 2AWG, wet-location-rated (THWN or XHHW-2) aluminum wire for both hots and the neutral with an 8AWG or 6AWG (8AWG works, 6AWG might be more useful for grounding electrode conductors though) bare copper ground wire. That will give you 70A at the garage without coming close to filling a 2" conduit.
How many outlets can be on a 15 amp circuit in a garage?
This works out to 180VA divided by 120 volts equals 1.5 amps per strap. Thats 10 receptacles on a 15 amp breaker.
What kind of wire do I need for a 20 amp circuit?
A 20-amp circuit, protected by a 20-amp breaker or fuse, must be served by 12-gauge or 10-gauge wire.

Where do you connect the black wire to the ground?
Connect your black and red wires to the screws that you see located on the breaker. The white wire will go to the neutral bus bar and the green wire will connect to the ground bus bar, much the same as the sub-panel box. Test out your sub-panel using a voltage meter.
Why do you need a ground rod for a sub panel?
If the building that you are running wiring into is detached entirely and has a sub panel that will be installed, it requires its own ground rod. This is regardless of whether or not you have three or four wires that are feeding into it. The purpose for this is because the ground is not a good conductor.
Where to connect white wire to panel box?
You will be connecting the white wire to the panel box’s neutral bus bar; this is generally on the side of your main bus. Lastly, connect the green wire to your ground bus bar. This is the one connected directly into the sub panel itself. Over in the main panel box, you will need to install the breaker on the main bus.
Do you have to run a sub panel to a main breaker?
