You have a 50A breaker on the input, so as long as the wires feeding that can handle 50A and the panel itself can handle 50A (gosh I’d hope so…) it’s safe. As long as the wires attached to your proposed 30A breaker can handle 30A, it’s safe.
Can I use a 30 amp breaker on a 50 amp wire?
To know the correct wire gauge, you can’t depart from local codes. A 30-amp breaker requires a 10-gauge wire, while a 50-amp one will need an 8-gauge one. This doesn’t take into consideration how long the wire run will be.
Can you run a 100 amp sub panel off a 50 amp breaker?
It’s a rating.
It’s the same with subpanels: The “100A” is a maximum rating. Do not exceed 100A. However, you certainly should exceed your feed-breaker size of 50A. Even if 50A panels existed, they would be very small in terms of numbers of spaces.
Can I add a 30 amp breaker to my panel?
Installing a 30-amp breaker and plug isn’t easy, but you can do this without having to hire an electrician. You may need to install a 30-amp breaker and plug because you are adding a laundry room and need to connect your dryer. Welders also run on 30 amps and would need a dedicated circuit for safe operation.
What can you run off a 50 amp sub panel?
A 50-amp breaker can run appliances like ovens, hairdryers, air conditioners, and multiple lights simultaneously while (possibly) still sparing power. The reason for this breaker’s capacity is because it can hold up to 12,000 watts running on a 240-volt circuit (50-amps x 240-volts).
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.
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 many amps can you put on a 50 amp panel?
A 50 Amp split phase 120/240 VAC service should be capable of 50 Amps per leg for a total ampacity of 100 Amps. It’s true that you have 50 Amp on each leg for 100 Amp total, but if you get up to 45 Amp continuous on one leg, you will trip the breaker.
Can a larger breaker feed a smaller breaker?
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 I put a 50 amp breaker in a 50 amp sub panel?
Assuming you’ve got 6 gauge wire feeding the sub panel, you should be fine. As long as you aren’t pulling more than 50 amps through that sub panel at once, you don’t need to worry about over loading the panel. That’s what the 50 amp breaker is there for.
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.
Can a subpanel feed another subpanel?
Answer: 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 many breakers can you have on a 60 amp sub panel?
Modern 60-amp electrical panels are purpose-built as sub-panels and generally only have 8 to 10 slots available for circuit breakers.
Does a subpanel 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.
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 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 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.
How many amps does a sub panel need?
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.
