A breaker or fuse in an electric panel is protecting the wire, outlets and switches that are part of the installed circuit. You could plug in an appliance that draws 6 amps and have a 15 A breaker protecting the circuit. The idea for protecting a specific device is to put in a fuse that blows before the current destroys the device. If your 6 Amp device would be destroyed by 6.1 amps then you want a 6 amp fuse. However, fuses aren't that precise so this would be hard to do. A rule of thumb is that the steady state current in a circuit is 80% of the over-current protection. In your case this would be 7.5 amps.
What else can I help you with?
Which size fuse should be used with a No 18 AWG extension cord where only two conductors are carrying current?
The protective device should be rated not more than 10 Amperes and be able to withstand a 1000Ampere short circuit.
Is a circuit breaker better than a glass fuse?
Each device has its own special use. Glass fuses can protect circuit at very low amperages. They are usually used to protect printed circuit boards and control panel circuits. Breakers protect circuits from short circuits and overloads. These devices are used in service distribution panels to protect the wires that feed the loads. Circuit breakers can be from 15 amps up into the thousands of amps.
What does fuse rating of 5 amps mean?
A fuse rating of 5 amps means that the fuse will break the circuit if the current passing through it exceeds 5 amps. It acts as a safety measure to protect the circuit from damage due to excessive current flow.
How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
Will 7 amps overload a household lighting circuit?
Lighting circuits (UK) are fused at 15A. If in doubt, check the fuse/MCB. Unless the 7A device is lighting, connecting it would be illegal in the UK. Don't forget anything else on the same circuit.
What is the recommended wire size for a circuit carrying 35 amps of current?
The recommended wire size for a circuit carrying 35 amps of current is typically 8 AWG (American Wire Gauge).
What is the recommended wire size for a circuit carrying 80 amps of current?
The recommended wire size for a circuit carrying 80 amps of current is typically 4 AWG (American Wire Gauge).
What size circut breaker for 10-2 wire?
A #10 wire has the capacity for 30 amps. No breaker larger than 30 amps should be used to protect the circuit.
What is the maximum amperage rating for a circuit breaker that can safely protect a 20 amp circuit?
The maximum amperage rating for a circuit breaker that can safely protect a 20 amp circuit is 20 amps.
What is the function of a 15 amp circuit breaker?
To trip when current is in excess of 15 amps and protect the circuit components.
Can you replace 2.5 Amps 125 Volts with 10 Amps 125 Volts?
You physically can but sit will be unsafe, and will not protect the circuit because it will not blow when it should. Only replace a fuse with the same size fuse.
Which size fuse should be used with a No 18 AWG extension cord where only two conductors are carrying current?
The protective device should be rated not more than 10 Amperes and be able to withstand a 1000Ampere short circuit.
How do you confirm that you are not overloading an outlet?
Check the number of amps that your circuit can handle. You should not put devices with more than that many amps (total) on that circuit. Most houses are 15 amps and bathrooms 20 amps.
Is a circuit breaker better than a glass fuse?
Each device has its own special use. Glass fuses can protect circuit at very low amperages. They are usually used to protect printed circuit boards and control panel circuits. Breakers protect circuits from short circuits and overloads. These devices are used in service distribution panels to protect the wires that feed the loads. Circuit breakers can be from 15 amps up into the thousands of amps.
What does fuse rating of 5 amps mean?
A fuse rating of 5 amps means that the fuse will break the circuit if the current passing through it exceeds 5 amps. It acts as a safety measure to protect the circuit from damage due to excessive current flow.
What is a 8a fuse?
A device that will protect an electrical circuit from overload up to a current flow of 8 amps
CAn you replace a 13 amp fuse with 15 amp fuse?
It will work but will not protect the circuit as it should. By design, the circuit should have a maximum of 13 amps, but with the larger fuse in place, currents of 14 and 15 amps can occur without blowing the fuse, and this flow could damage parts of the circuit. It would be much safer to use a lower value, which would lead to more blowing of the fuse but no damage to the circuit being protected.
