Answer for UK, Europe and countries running a 50 Hz supply service.It is acceptable to connect two 15-amp breakers to a 30-amp supply. It woud also be acceptable in some applications to connect three 15-amp breakers if it were known that the total current would not exceed 30 amps. For example in many UK properties there is a 60-amp supply, and connected to this there are two 30-amp supplies for the ring-circuit and the cooker, plus also a 10-amp lighting supply.
20-amp breakers can be found for many different voltage levels. The higher-voltage ones tend to be more expensive. A breaker can be used in a circuit of equal or lower voltage than the rated voltage of the breaker.
20 Amp * 120 Volts = 2400 Watts 2400 Watt * 80% max use = 1920 Watts planned normal usage for a circuit with a 20 Amp breaker.
In the United States, there isn't a hard limit on how many 20 amp circuits that can be run on a 50 amp supply. This is because in most cases, especially in homes, we don't load most circuits with more than an amp or 2, even when they are protected by a 20 amp breaker. From a practical perspective you probably have a limited number of slots for breakers in your service or supply panel.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
It depends on the supply voltage watts = current in amps times the supply voltage

Let's start with a typical 110 VAC service. You probably have 20 amp breakers in the service in the garage, and with at least 2 breakers, we have some idea of the theoretical electrical consumption. Remember, Volts X Amps = WATTS, so 110VAC X (2 breakers X 20AMPs) = 110 X 2 X 20 = 2200 WATTS

600 watts
The formula for watts is, Watts = Amps x Volts.
