The answer to 'which is better 100 amp panel or 200 amp panel' is that a 200 amp electrical service panel is generally better than a 100 amp panel for most modern homes. A 200 amp panel provides more electrical capacity to power your home's growing number of electrical devices and appliances.
The main benefits of a 200 amp panel are increased electrical capacity, improved safety, and better future-proofing for your home. A 200 amp panel can handle higher electrical loads from things like electric vehicles, heat pumps, and large appliances. It also has more available circuit breaker spaces, reducing the risk of overloading circuits. This makes a 200 amp panel a better choice for most homeowners, especially those with larger homes or plans to add more electrical devices in the future.
