The main breaker is typically labeled with a number such as 100, 150, or 200, indicating the amperage your home can safely handle. Many older homes in Austin and San Antonio still have 100-amp service, which may be insufficient for modern electrical loads.
Service size affects whether your home can support upgrades like new air conditioning systems, electric vehicle chargers, or additional circuits. If the label is missing or unclear, a licensed electrician can confirm the service size safely.
Radiant helps homeowners identify their service capacity and understand whether an upgrade is needed to support current or future electrical demands.
