How far can I run a sub panel from the main panel?
The right feet would be between 4.5 to 5 feet.
The cable running from your main panel to the subpanel depends on the amperage rating. For instance, for a 30A panel, use a 10 AWG, three-wire conductor. If you have a 60A panel, use a 6 AWG wire.
Does my sub panel need a main breaker?
The subpanel may be equipped with a main breaker to allow for power interruption without having to go back to the main panel, but it is not required to have a main shutoff circuit breaker, since the feeder breaker back in the main panel serves this function.

Does a subpanel in the same building need a ground rod?
You must, must, must, in every case run a ground ~ from the main to the subpanel. Doesn’t matter if you’re running it 3 feet, to an outbuilding or up a space elevator. You have to run a ground ~ or you are out of Code.
Should a subpanel be bonded?
Rule #3: In a subpanel, the terminal bar for the equipment ground (commonly known as a ground bus) should be bonded (electrically connected) to the enclosure. The reason for this rule is to provide a path to the service panel and the transformer in case of a ground fault to the subpanel enclosure.
Does a subpanel need a ground bar?
Yes, any sub panel outside of the main building requires it’s own ground rod and a ground wire back to the main building.
Why would I need a sub panel?
An electrician might add a sub panel to take the load off of the main circuit breaker panel. This can prevent overloading the electrical system and tripping circuit breakers or melting fuses. Sub panels are also used to separate the electrical needs of specific areas.
How much does it cost to add a subpanel?
between $400 and $1,750
The average cost of installing a subpanel is between $400 and $1,750, depending on the amperage and number of circuits installed. Typically subpanels have 4 to 20 or more circuits and between 100 and 150 amps.
Is a subpanel a branch circuit?
Subpanel Power Supply
Answer: In short, yes. The main electrical service panel is where branch circuits originate.
When should I add a subpanel?
If you happen to live in an older home, the size of your main breaker panel may only allow for 12-16 circuits, meaning you will certainly have to add a sub-panel to maintain constant, uninterrupted power flow to your new appliances.

Can I run a 100 amp sub panel off 200 amp main?
Can you add a 100 amp breaker to your main panel? Yes you have 12 slots the double pole breaker will only take 2 slots.
Can I run a 100 amp sub panel off a 100 amp sub panel?
Let me try and answer some of your questions. First the panels you are looking at that are rated 100A simply means you can use them for any application up to 100A.
Can you run an electrical sub panel off a sub panel?
Answer: Yes. The main electrical service panel is where branch circuits originate.
Can I run a sub panel off of another sub panel?
Can I run a subpanel from a subpanel? Generally speaking, yes. You could put a million subpanels in series, and by itself that wouldn’t be a code violation. The metal conduit can act as the equipment ground so a 4th wire is not required.
How many circuits can be on a 60 amp subpanel?
Modern 60-amp electrical panels are purpose-built as sub-panels and generally only have 8 to 10 slots available for circuit breakers.
What is the 6 breaker rule?
The “six breaker throw rule” was a requirement in the National Electrical Code that a service must have have a main disconnect that shuts off all power and it cannot take more than six switch throws to do it, and the main disconnect(s) also must be clearly marked, as in the photo above.
How many breakers can you have in a 30 amp sub panel?
The amount of current that is required for the connected loads can only be supported by a 30 Amp sub-panel. The maximum quantity of branch circuits can be determined with a load calculation. Two 15amp breakers or one 15amp and one 20amp can be used on a 30amp circuit.
What size breaker do I need for a subpanel?
Based on your question, since you will be having a subpanel, you want the breaker feeding the subpanel to be sized for the subpanel or slightly smaller. So if you purchase and install a 200A subpanel, then the breaker should be 200A. If you use a 125A subpanel, then use a 125A breaker.
How far can you run 12 gauge wire on a 20 amp circuit?
After these distances, the circuit will go over the recommended 3% voltage drop. You can run a 12 gauge wire up to 70 feet on a 15 amp circuit. That number drops to 50 feet if you run 12 gauge wire on a 20 amp circuit.
