Yes. The main panel breaker feeding that sub panel controls the maximum power capacity.
Can a sub panel have more amps than a main panel?
You are fine. The 200 amp breaker in the main panel will protect the wires leading to the sub. The main breaker in the sub is not strictly necessary, except as a local shutoff. You could as easily use a sub designed with no main, feeding directly to the bus bars.
Can a sub panel have 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.
Do I need a feeder breaker for a subpanel?
If the main panel’s MAIN breaker is of a size that will adequately protect the feeder wires and the subpanel, then no breaker is needed.
Can I put a higher amperage main breaker in?
When the breaker is tripping, it is almost never a good idea to replace it with a larger one. Here’s why: It increases the risk of fire. If the breaker is tripping because it’s overloaded (say, drawing 25 amps on a 20-amp breaker), increasing the size may cause the wire or the receptacle to overheat.
Can I feed a 200 amp sub panel with a 100 amp breaker?
Yes. There is no real NEC provision that would prohibit this so it’s allowed. The 200 amp CB is simply being used as a disconnect if the feeder is protected by a 100 amp OCPD at it’s origin.
Can you feed a 100 amp panel with a 200 amp breaker?
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 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.
How big of a sub panel can I install off 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.
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.
Can a 60 amp breaker feed a 100 amp sub panel?
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.
Can you 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.
Can you use a 100 amp breaker for a 125 amp sub panel?
If it’s a 125 amp panel, then you can use a 100A breaker on the main panel to feed the breaker. The new sub panel must always have the same ampacity rating as the panel that is feeding it.
Can you put a 50 amp breaker in a 100 amp panel?
The number of breakers can max out to 30-42, too, depending on the design of your 100-amp pane. However, NEC prohibits more than 42 circuits, so you can only choose between 20-42 breakers for a 100-amp panel. Breakers or circuit breakers act as a switch for cutting off power from the main electrical supply.
