Can I make my main panel a sub panel?

There’s no problem with having a main breaker in a subpanel. It’s required if your panel is in a separate building and has more than six breakers, but there’s nothing prohibiting it in any other case.

Can I run a sub panel off 100 amp main?





If you have older 60-amp or 100-amp main service, it is entirely possible that you will need a service upgrade to 150-amps or 200-amps before you are able to adequately power a new subpanel.

Can a 200 amp panel be a sub panel?

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.

Do I need a ground from main panel to subpanel?

The biggest difference between a subpanel and a main panel is that the ground and neutral buses on a subpanel have to be separated. Most panels come with a bar joining the two, which is easily removed. Code requires subpanels to have a ground connection that’s independent of the main panel’s.

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 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.

How many subpanels 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.

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 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.

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.

Why do you not bond a sub panel?

So, why do you separate the ground and neutral in a subpanel? Because when we bond them together, it gives your neutral wire (the one carrying electrical currents BACK to the source) multiple pathways. That’s how the chassis of some equipment will become energized.

Can neutral and ground be connected together in main panel?

The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.

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.

Does a subpanel need a main breaker?

Subpanel main breaker
A main breaker on a sub-panel is not necessary because this is in the same building (if you are in a different building then NEC 225.31, 225.32, 225.33 apply). That said, having a main breaker in the sub-panel is also acceptable.

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.

Should I add a sub panel or upgrade main panel?



Because there are only so many switches on a main electrical panel, subpanels can be useful to add extra room. Because the two panels are very similar and are connected to the same flow of energy, the subpanel is useful if you want to have more room for circuits in your house.

What is the difference between a main breaker panel and a sub panel?

A main panel is an installed box where the power from the utility company enters the premises. A subpanel is an installed features that acts as a middle ground for the main panel and other types of circuits that are connected to your property.

When should I add a subpanel?

A sub panel is a necessary addition to any home that runs a lot of electronics or has extra rooms with a heavy load of electrical requirements. Sub panels are often added when a garage, basement, or extra room is converted into a home theater, workshop, or home office.

How much does it cost to install a sub panel?

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.

How many circuits can a subpanel have?

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.
