Generally speaking an appliance (eg tv) is supplied with power so when it is off it has voltage supplied. After yo turn it on it starts to draw power called amperage the voltage doesn't get higheur but the amperage does
Amperage is the load being drawn through a circiut
An amperage relay is an electrical device used to activate or deactivate a circuit based on the current flowing through it. It is designed to protect the circuit from overload or short-circuit conditions by opening or closing the circuit when the preset amperage level is exceeded.
The range of amperage for the electrical circuit in question is between 15 to 20 amps.
The maximum amperage rating for a circuit breaker that can safely protect a 20 amp circuit is 20 amps.
The maximum amperage capacity of a 60 amp circuit breaker is 60 amps.
The maximum amperage capacity of a 90 amp circuit breaker is 90 amps.
The maximum amperage capacity of a 150 amp circuit breaker is 150 amps.
The maximum amperage capacity of a 30 amp circuit breaker is 30 amps.
amperage
Fuses are based upon the size of the wire of the circuit that it is to protect. The wire is sized by the amperage of the connected amperage load of the circuit.
The maximum amperage capacity of the circuit protected by 30 amp breakers is 30 amps.
The recommended amperage for a circuit protected by a 50-amp breaker is 80 of the breaker's rating, which is 40 amps.
The recommended amperage for a 30 amp RV circuit breaker panel is 30 amps.
