Of course you can, you can add the 100 amp breaker to your 200 amp as long as it isn’t overloaded, to start adding the subpanel you must first calculate how many yards it will be from the main panel to the subpanel, there is a formula that calculates how much friction will be on the wire at the connecting distance, ….

Can you run a 100 amp sub panel off a 100 amp main 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. You can for example add a 60A breaker to your existing panel and protect the new subpanel with a 100A rating.
Can you daisy chain sub panels?
Answer: Yes. The main electrical service panel is where branch circuits originate.
How many sub-panels can you have on a 200 amp service?
200 AMP Service – Feeding 3 Sub-Panels – Wire Size and Set Up Help Needed.
How much does it cost to install 100 amp sub panel?
The cost to update an electrical panel to 100-amp service is $500 to $1,500. The box runs $50 to $200, so labor is the biggest part of the total. Older homes often run low-amperage boxes because they didn’t have central air, modern appliances, or today’s electronics in mind.
How much does it cost to rewire a 1500 sq ft house?
Cost to Rewire a House Per Square Foot
| Square Feet | Average Cost |
|---|---|
| 1,000 | $1,650 – $3,800 |
| 1,200 | $2,000 – $4,500 |
| 1,500 | $2,350 – $5,700 |
| 2,000 | $3,200 – $7,700 |

Why should I upgrade to 200 amp service?
Greater Capacity
A 200 amp service panel will provide more electrical current than a 100 amp panel, allowing a home to safely power large electrical appliances and heating and air conditioning equipment, and other appliances simultaneously.
How many circuits can be on a 40 amp sub panel?
A 40A/240V panel can support as many as 10 or more 120V/15A circuits, presuming they won’t all be heavily loaded at the same time. You might even be able to upgrade the power feed later. Many panels are sold as 4 spaces/8 circuits.
How do I know if I can add a subpanel? Adding a Subpanel
You’ll need to consider the amount of available power load you’ll need and what the main service has to offer. For example, if you have 200-amp main service, you’ll have no problem adding a 100-amp subpanel to feed a shed, garage, or barn.
How many sub panels can you have on a 200 amp service?
Even though there is no limit on the number of subpanels that you can add to a circuit, it shouldn’t exceed 160 amps when you’re using a 200 amp main panel. Always follow this guide to install subpanels effectively.
Can I run a 200 amp sub panel off 200 amp main?
Is feeding a 200A sub from a 200A main legit? Yes, and you don’t even need another 200A breaker. The 200A breaker alread present in the panel will suffice, and so you can use a subfeed lug kit as DrSparks advises.
How can you tell if a panel is overloaded?
One of the most common indications of an overloaded electrical panel is breakers that trip frequently. While it is common to trip a beaker occasionally, if one or more breakers trip often, even after moving devices to other circuits, it may be time to add additional circuits or to upgrade your service panel.
What size breaker do I need for a 200 amp sub panel?
In the case of 200 amps breakers, this means you will need a wire with at least 250A ampacity to connect a 200 amp service. Looking at the AWG wire chart, you will need an even bigger than #0000 AWG wire for 200 amps.
How many amps can a 100 amp panel handle?
For example, a 100-amp service panel could have circuit breakers that add up to more than 200 amps.
What do you do when your breaker box is full? If your home’s electrical service panel (breaker box) is full and you need more room to add new circuits, installing a subpanel might be the way to go. Subpanels certainly can add convenience and plenty of room for installing new circuits, but your current system must have enough capacity to support a subpanel.
How much can a 200 amp panel handle? As mentioned above, using a 200 amps panel means that you have a maximum of 24,000 or 48,000 watts available for your appliances. The watts denote the amount of power that flows into the house.
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.
How far can sub panel be from main panel?
You may not know this voltage, so it’s best to provide 4 feet. The panel must be easily accessible, so don’t install it too far above the floor; 4.5 to 5 feet is about right. The cable you run from the main panel to the subpanel also depends on the amperage rating.
What kind of breaker do I need for a sub panel?
A subpanel requires two hot wires connected to a 240-volt double-pole breaker in the main panel. It also needs a neutral wire and a ground wire.
Can you feed a 100 amp sub panel with a 60 amp breaker?
You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.
Is a sub panel a branch circuit?
Subpanel Power Supply
Answer: In short, yes. The main electrical service panel is where branch circuits originate. A branch circuit consists of the circuit conductors between the final over-current device protecting the circuit and the lights, receptacles and equipment supplied by the branch circuit.
How far can a subpanel be 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.
Can I run a subpanel off another subpanel?
Answer: Yes. The main electrical service panel is where branch circuits originate.
What size breaker do I need for a sub panel?
Subpanel Circuit Breaker Sizing
To calculate the breaker size, simply divide the adjusted wattage by 240 volts to find the rated amperage needed for your subpanel. Often, the result is not a common circuit breaker size. and you can simply round up to the next higher size of the breaker.
Is 100 amps enough for a house? Most homes require an electrical service of at least 100 amps. This is also the minimum panel amperage required by the National Electrical Code (NEC). A 100-amp service panel will typically provide enough power for a medium-sized home that includes several 240-volt appliances and central air-conditioning.
How many outlets can be on a 15 amp circuit?
Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.
