The amperage that can be used from a service distribution panel is governed by the amperage of the main breaker. If the main breaker is 200 amps then up to a maximum of 200 amps can be taken from the panel before the main breaker trips on an over current fault.
ANSWERBreaker panels come in a variety of sizes. The current capacity of the breaker panel and its main breaker are governed by the current capacity of the service wiring provided by the electrical supply company. 50 years ago, 60 ampere service was common. Now the smallest common household service in North America is 100 amperes. It is becoming more common to install 150 or 200 ampere service, especially in upscale homes
One "planning ahead" approach is to get 100 ampere service, but install a 200 ampere breaker panel with a 100 ampere main breaker. That way, if you ever upgraded to 200 ampere service, you'd already have the correct panel and wiring, and all you'd have to do is take out the smaller main breaker and replace it with a 200 ampere unit
For business installations, main breaker panels can be considerably larger. For example, consider a typical roadside hotel (50-75 rooms) or small apartment building (15-20 apartments) with HVAC (individual electrical heat and air conditioning units ). You can think of it as a gigantic house, everything that's in your house but on a larger scale. A 1600 ampere 3-phase main breaker would probably be used, with a distribution panel providing 200 ampere single phase breakers to feed power to 200 ampere subpanels throughout the building.

Single pole refers to a circuit breaker that interrupts the current flow of one hot wire, while double pole interrupts the current flow of two hot wires simultaneously. In a 240-volt circuit, a double-pole breaker is used to control both the hot wires, providing higher safety protection as both sides of the circuit are disconnected.
A 30 amp circuit can handle a maximum of 30 amps of current flow continuously without tripping the circuit breaker. It is important not to exceed this amperage to prevent overheating and potential fire hazards.
20 amps on the circuit will trip it unless it is is broken. Then it may trip with a lower current or not at all... Any resistance added to the circuit from a bad or dirty connection will add to the total current causing it to trip sooner than expected.
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.
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
A 15 amp circuit breaker should trip at 15 amps regardless of the load voltages or impedances. If you have 277 volts and 7 ohms, the current would be 39.5 amps and a 15 amp circuit breaker should trip.

A circuit breaker(s) is what you will find inside your electrical box in your house the idea behind them is when a room in your house draws too many Amps the circuit breaker will turn off all the power to that room to re-engage them you simply switch it back on. There are many types of circuit breakers with different rattings like 15A or 100A, this tells you at what point they will 'break' the circuit and turn off the power.

The size of the amp circuit breaker needed for a geyser will depend on the specific electrical requirements of the geyser. It is important to consult the geyser's manufacturer specifications to determine the appropriate amperage for the circuit breaker. Typically, a 20-amp circuit breaker is commonly used for residential geysers, but larger geysers may require a higher amperage circuit breaker. It is crucial to ensure that the circuit breaker is properly sized to prevent electrical hazards and ensure safe operation of the geyser.
A 400 watt heater can safely be used on a 15 amp circuit. The size breaker needed for a circuit is determined by the size of the wiring in that circuit. AWG #14 wire requires a 15 amp breaker. AWG # 12 wire requires a 20 amp breaker.
120 amps The above answer is wrong. A 60 amp breaker is designed to trip at 60 amps be it a single pole, double pole or a triple pole that is used on three phase equipment. The number on the handle of a breaker is the trip capacity.
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
The formulae for calculating watts to amps is Watts divided by Voltage. Therefore to get from Amps to Watts the calculation is Amps × Voltage. Therefore if you are working on a 240 volt supply the calculation is 20 (Amps) × 240 (Volts) which = 4800 watts.
