100 amp service refers to the electrical capacity of a home or building’s electrical system, indicating that it can handle a maximum of 100 amperes of current. This rating determines the amount of power available for appliances and devices; it’s essential for ensuring that the electrical system can support the needs of the occupants without overloading. In residential settings, 100 amp service is typically sufficient for smaller homes or those with fewer electrical demands. Upgrading to higher amperage can be necessary for larger homes or modern electrical needs.

Do i need a new service drop line to change from 100 mp service to 200 amp service?

Yes, you will likely need a new service drop line to upgrade from 100 amp to 200 amp service. This is because a 200 amp service typically requires a larger gauge wire and potentially a different type of service drop to safely handle the increased load. It's best to consult with a licensed electrician to assess your specific situation and ensure compliance with local electrical codes.


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.

What are the differences between a 100 amp service and a 200 amp service for residential electrical systems?

A 100 amp service provides less electrical capacity than a 200 amp service for a residential electrical system. This means that a 200 amp service can handle more electrical load and is better suited for larger homes or homes with higher electricity needs.

No, each size service needs its own meter base.


Can you tap off of a 200 amp service for 2 100 amp panels?

Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor. From the 200 amp feeder panel you will require a 100 amp two pole breaker for each of the two 100 amp services. Keep in mind that if you run the 100 amp services close to maximum this will take away the capacity of the 200 amp service for other branch circuits coming off of it. Also keep in mind that if the panels are located, not in the same building as the 200 amp service that the 100 amp panels will be treated as separate services and will have to be constructed like a 100 amp service. This includes ground rods. Also the bonding screw will have to be removed that connects the neutral buss to the panel enclosure.
