Yes, a GFCI breaker can protect the feeder going to a subpanel. The GFCI protects whatever is downstream of it; when that happens to be a subpanel then all the circuits in that panel are protected. I used this technique in my detached shop building.
Can you feed a subpanel with a GFCI breaker?
The answer is YES, they do make a 50A GFCI (Class A) Circuit Breaker that can be used on a feeder (same as it would be used on a branch circuit to a hottub).
Can you feed a GFCI breaker with a GFCI breaker?
Yes, it can be done. There is no problem having a GFI fed from another GFI.
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.
Can you feed a subpanel with a smaller breaker?
This must be fed by a 125A or smaller breaker in the main panel. Panel rating is the limiting factor. 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. Remember: subpanels NEVER need main breakers.
Does a GFCI need to be on its own circuit?
Individual GFCI outlets do not have to be on their own circuits. The only reason I can think of that would be a safety concern would be if the GFCI’s were not listed for outdoor use or not in weatherproof boxes. They are gfci outlets and they are both in weatherproof boxes. Inspectors are often wrong.
Can you put 2 GFCI outlets on the same circuit?
Having 2 GFCIs on the same circuit has no added benefit and can cause the occupant confusion when it comes to tracking down a tripped GFCI outlet. When the GFCI is installed on the lead outlet, there is no need to wire multiple GFCIs on the same circuit for residential use.
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.
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 you feed a 100 amp sub panel with a 50 amp breaker?
Just wire it up. There is no problem using a sub panel that can take more current than you will ever feed it. Points to note: The cable to your hot tub will be rated for 50A (not 100A); therefore you must not upgrade the breaker in your main panel to 100A.
Can you run a 100 amp sub panel off a 200 amp main panel?
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, …
What size breaker Do I need to feed 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.
What size Sub Panel Can I run off 100 amp main?
The size of a sub panel for a workshop should be a minimum of 60 amps up to 100 amp power feed from your house or main service. This is assuming that you have at least a 200 amp main service. It should be 120/240 volt single phase.
How far can subpanel be from 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.
Does a subpanel need a ground rod?
Yes, any sub panel outside of the main building requires it’s own ground rod and a ground wire back to the main building. And yes, a sub panel in the same building as the main does not need a ground rod – only the ground wire.
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 subpanel 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.
Can you daisy chain sub panels?
Answer: Yes. The main electrical service panel is where branch circuits originate.
