No. you cant because that is way too much current (amperage). Think of a circuit.

You should NEVER connect a 100 amp service to a 200 amp breaker, as you might do with the 200 amp mains in the panel you have. However, if your service conductors are long enough or can be extended, you can connect your service conductors to a 100 amp breaker installed as you would any other breaker in the panel. You would simply ignore the 200 amp main breaker.

You might end up with an inspection problem if at some time that becomes necessary. And you might have to make it right for the sale of a property. But electrically, if you connect your service to a 100 amp breaker, "the electrons don't care," as I like to say it. But you only have 100 amps available.

Can I use a 100 amp main panel as a sub panel for a 200 amp service?


Can you install 200 amp to run a 100 amp panel and a 200 amp panel?

Yes but if the total current exceeds 200 amps the panel will be overloaded and the main breaker will trip.

Is my home 100 or 200 amps?

Your main service panel will have a plate or sticker telling you.

Can you install 200 amp service Panel in washer Dryer closet?

No, you can not install a service panel in a washer/dryer closet. The National Electrical Code (US) requires you to maintain work space in front of the panel (3' deep and 30" wide)

Can you feed 200 amps to 100 amp panel?

The rating of a panel dictates the maximum current of the panel and is protected by a breaker of that rating. If you had 200 amp service to your house and only had a 100 amp panel then you could only draw 100 amps before the breaker tripped.

How much is a 3 phase 200 amp service panel?

The service panel itself is probably less than $200.

Can you install 100 amp service in 200 amp meter base?

No, each size service needs its own meter base.

How do you upgrade 100amp to 200amp service but keep the 100amp as a subpanel of the new service?

Judging by your question I'm going to take a guess and say you should probably not attempt to do this yourself. Nor do I recommend it. That being said. You can either have your service upgraded to 200amp, and install a 100amp double pole breaker and branch it off into a 100 amp sub panel. You could most likely re-use your old panel for the 100 amp sub panel. Or... You could have your new 200 amp panel installed in a different location and your current panel wired into it for 100 amps.

What is the minimum service size for a 225amp residential service?

A 200 amp service panel with a 60 amp sub-panel.

Can I install 200 amp panel using 200 amp meter?

A 200 amp meter has to be used on a 200 amp distribution panel. As to your ability of installing this service depends upon your skill, workmanship and knowledge of installing electrical equipment and to be able to get it inspected and passed by an electrical inspector.

Is a 100 amp sub panel too much for a 200 amp main panel?

no .If you max out the sub panel you have 100 amp in the main panel

What size wire for 100 amp panel 200 feet away from a 200 amp service?

This is a voltage drop question. A voltage value needs to be stated. Assuming that the 200 amp panel is a single phase 120/240 volt sub panel. A #1 copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 200 feet on a 240 volt system.

Do you need to rewire your house to upgrade your panel to 200 amps?

No, you can just install a 200 amp service with your existing wiring. But, you need to make sure the wiring is safe and not deteriorated to the point it has become dangerous.

What is the difference between 100 amp service and 200 amp service?

The difference is 100 amps

What size neutral wire is needed for a 200 amp service panel?

The neutral is the same size as the feeder conductors for a 200 amp service.

How do you determine if you have 100 or 200 amp service?

Look at the value of the breaker or fuses that control your main electric panel. look at the wire size coming in to the main lugs on service panel, I am assuming you don't have a main breaker or you would look at the breaker rating to determine service size. 2/0 copper or 4/0 aluminum service size 200 amps, #4 copper or # 2 aluminum 100 amp.

Can you feed a 100 amp panel from your 200 amp panel?

Yes. You need to balance loads since you are not getting an extra 100 amps, your overall limit is still 200 amps.

What size wire for 100 amp sub panel 200 feet away from a 100 amp service?

This is a voltage drop question. A voltage value needs to be stated. Assuming that the 100 amp panel is a single phase 120/240 volt sub panel. A #1 copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 200 feet on a 240 volt system.

How hard is it to change from a 100 AMP fuse-box to a 100 or 200 amp breaker panel?

It depends on your skill level. Not difficult to change it to a 100 amp panel if you know what you're doing but to upgrade to a 200 amp panel requires quite a bit more effort. This is assuming it is the main panel and not a sub off a 200 amp main.

Can you change 100 amp breaker to a 200 amp breaker in the 100 amp box?

No, absolutely not. The wiring supplying your 100 A panel can only carry 100 amps, not 200 A !If you were to install a 200 A main breaker and then draw more amps than the supply wire can carry, it would overheat and burn. Good way to burn your house to the ground.

How many amps are in a breaker panel?

ANSWERThe amperage that can be used from a service distribution panel is governed by the amperage of the main breaker. If the main breaker is 200 amps then up to a maximum of 200 amps can be taken from the panel before the main breaker trips on an over current fault.ANSWERBreaker panels come in a variety of sizes. The current capacity of the breaker panel and its main breaker are governed by the current capacity of the service wiring provided by the electrical supply company. 50 years ago, 60 ampere service was common. Now the smallest common household service in North America is 100 amperes. It is becoming more common to install 150 or 200 ampere service, especially in upscale homesOne "planning ahead" approach is to get 100 ampere service, but install a 200 ampere breaker panel with a 100 ampere main breaker. That way, if you ever upgraded to 200 ampere service, you'd already have the correct panel and wiring, and all you'd have to do is take out the smaller main breaker and replace it with a 200 ampere unitFor business installations, main breaker panels can be considerably larger. For example, consider a typical roadside hotel (50-75 rooms) or small apartment building (15-20 apartments) with HVAC (individual electrical heat and air conditioning units ). You can think of it as a gigantic house, everything that's in your house but on a larger scale. A 1600 ampere 3-phase main breaker would probably be used, with a distribution panel providing 200 ampere single phase breakers to feed power to 200 ampere subpanels throughout the building.Please read discussion page about the statement in bold print above.

How much electrical service panel size for a house?

In new home construction in North America the panel installed is usually a 200 amp distribution service.

Do you need to change the wire size going from 100 amp service to 150 amp service?

Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.

Ground wire size for 200?

A 200 amp service panel will require a # 4 bare copper ground wire.
