The more appliances you’d like to run at the same time can be a good indication of your service needed. For example a 60 amp service will not provide enough service to run an electric stove, hair dryer and electrical hot water heater. The rule of thumb for our many digital devices that need to be on charge and appliances running in the background we’d suggest 200 amps.
Resetting circuit breakers or changing fuses too often: could indicate that your circuits are drawing more current then they can safely provide. It could also indicate a more dangerous fault in one or more circuits that needs immediate attention.
