## Can I put a 30 amp breaker in place of a 15 amp breaker?

2 Answers. This simply will not work. The only receptacles you are allowed to put on a 30A breaker are 30A receptacles. … The right way to do this is to fit a sub panel at the shed, and have individual circuit breakers protecting each #14 or #12 circuit.

## Can you run a 100 amp sub panel off a 100 amp main panel?

You can run a 100 amp subpanel off a 100 amp main panel because the total can be up to twice the amperage of the box, meaning you could run a subpanel of up to 200 amps. What’s critical, though, is that the subpanel is safely and correctly connected to the main panel and that you don’t overload the service panel.

## Do I need a disconnect for a sub panel?

Does the sub panel require a main disconnect? Thanks for your help. NO it does not. A detached building fed from another building would require a disconnecting means nearest the entrance of the feeder conductors into the building.

## How many amps can a sub panel be?

These are typically homes with 300-amp or 400-amp service, where there is one 200-amp main panel, plus second 100-amp or 200-amp panel. In this case, though, neither panel can be described as a subpanel—they both are main panels, and both have their own main shutoff breaker.

## 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.

## Will a 12 2 wire carry 30 amps?

You already stated what the Wattage and Amperage of the Heater was. Turn off the 30 amp breaker and add up all the heaters that are on that circuit. So long as the total draw for all of them is under 3800 watts, then a 20 AMP breaker using 12-2 wire is perfectly fine.

## What can I run off a 30 amp breaker?

In a typical RV with a 30 amp electrical service some of the power hungry appliances and portable devices are the air conditioner, electric water heater, microwave, coffee maker, electric skillet, hair dryer, space heaters and a toaster.

## What size breaker do I need for a 60 amp subpanel?

In practice, however, it’s common to wire 60-amp breakers with 6-gauge, 3-conductor wire because an appliance that needs a 60-amp breaker seldom draws the full 60 amps. If you’re installing a 60-amp subpanel, however, it’s best to connect it to the main panel with 4-gauge wire.

## Can you feed a 100 amp sub panel with a 60 amp breaker?

Nope. The breaker protects the wire leading to that subpanel. The “100 amp” rating of the subpanel is the max rating that you can feed it at.

## What size wire should I use for a 30 amp breaker?

## How many plugs can you put on a 30 amp breaker?

There is no limit to how many receptacles can be put on a circuit in a residence. In a commercial setting there is a limit to how many receptacles can be on a circuit but 120 volt 15/20 amp receptacles still cannot be on a 30 amp breaker. Receptacles must be 30 amp rated such as is used for an RV.

## Can I use a 30 amp breaker on 12 gauge wire?

12 gauge wire is rated for a maximum of 20 amps. You need a minimum of 10AWG wire for 30 amps.

## 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.

## Does subpanel need ground rod?

It’s not used unless a ground fault occurs, in which case it’s only purpose is to provide a path back to the source so that a protective device will trip. (breaker, fuse, etc.) … So for your first question: no, it is not against code to install a ground rod at the subpanel. It is actually required by code.

## Is a double pole 30 amp breaker 60 amps?

A main breaker is a large-amperage double breaker, same as any double breaker in the breaker box, except it supplies power to each busbar. So your question is like asking if you can draw 60 amps off a 30 amp double breaker … the answer is NO.

## What size breaker Do I need to feed a 100 amp subpanel?

You can use the 100 amp panel off a 60 amp breaker if you determine that it is adequate, but I would suggest that in sizing your feeder wires and conduit it would be a good idea to size them to accomodate 100 amps. Your feeder wires are where most of the work for this project will be.

## What is the 6 throw rule?

The “rule of six” refers to how many breakers or throws it takes to disconnect a building from the electrical supply, so if you have more than six breakers in a box at your service entrance there needs to be a disconnect upstream of it, either in the panel or upstream.
