Most residential homes have a ‘single phase’ or ‘three phase’ connection supplying 230 volts. For a modern family home, this connection is often 60 amps for a single phase, or 32 amps across three phases. Your fusing could be more or less if your house is smaller, larger, or was built at a time when fewer electrical devices were used around the home.
Small commercial buildings usually need more capacity, such as 100 or 200 amps. Large commercial stores or warehouses could need 400 amps to 1200 amps of capacity depending on their size.
Your capacity needs will vary depending on the amount of power you are using at your property, and there is no “standard capacity” or one-size fits all.
