For a standard 30 amp breaker, you should use a minimum of 10-gauge copper wire or 8-gauge aluminum wire. This size ensures that the conductor can safely handle the load without overheating. Always consult local electrical codes and regulations, as they may have specific requirements for wire sizing based on the installation conditions.

A range name plate says 78 amps what size breaker needed?
To determine the size of the breaker needed for a 78 amp range, you typically need to use a breaker that is the next size up from the amp rating. This means that you would need an 80 amp breaker to safely accommodate the 78 amp range. However, always consult with a qualified electrician to ensure the correct breaker size for your specific electrical setup.
Can I use a 30 amp disconnect switch non fused on 30 amp breaker with wire size 8 and its running a 25 amp shop heater?
Yes you can. In fact you can use #10 copper conductor with an insulation factor of 90 degrees C because it is protected by a 30 amp rated breaker. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps. The only time you need to go to a larger size conductor is when you have to overcome voltage drop on longer runs.
What size wire does a 70 amp breaker require?
A breaker is sized by the conductor that is connected to it but also the load that is connected to the breaker. There are some cases such as motor loads where the breaker has to be 250% of the motors full nameplate amperage.A #4 aluminium conductor with an insulation factor of 90 degrees C is rated for 75 amps.
What size aluminum wire does a 60 amp breaker need?
A breaker is sized by the conductor that is connected to it but also the load that is connected to the breaker. There are some cases such as motor loads where the breaker has to be 250% of the motors full nameplate amperage.A #6 aluminium conductor with an insulation factor of 90 degrees C is rated for 55 amps.
What amp fuse do you use for a 100 watt bulb?
Fuses or breakers are used to protect the conductor to the load. A #14 wire conductor is rated for 15 amps. Most home circuitry is done with #14 wire. The minimum size breaker in an electrical panel is 15 amp so it looks like a 15 amp fuse or breaker can be used for a 100 watt light bulb.
What size breaker for?
For a standard size refrigerator, a dedicated 15 amp circuit is used.
What are the standard size circuit breaker amperages?
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.
What size breaker should be used for a fridge?
For a standard refrigerator, a 15-20 amp circuit breaker is typically recommended.
A range name plate says 78 amps what size breaker needed?
To determine the size of the breaker needed for a 78 amp range, you typically need to use a breaker that is the next size up from the amp rating. This means that you would need an 80 amp breaker to safely accommodate the 78 amp range. However, always consult with a qualified electrician to ensure the correct breaker size for your specific electrical setup.
What amp breaker do you need for a 325 watt heater 120 VAC?
Electrical breakers are sized by the conductor that is connected to it. The conductor is sized by the current that is drawn by the circuit. The formula for amperage is I = W/E. Amps + Watts/Volts. 325/120 = 2.7 amps. A #14 copper conductor is rated at 15 amps. This is the minimum size wiring that is used for house circuits loads. The breaker for this size wiring will be a 15 amp breaker.
Can I replace a 15 amp breaker with a 20 amp breaker?
No, you should not replace a 15 amp breaker with a 20 amp breaker without consulting a licensed electrician. The breaker size should match the wire size to prevent overheating and potential fire hazards.
What size breaker can you use on a 7500watt generator?
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
What size breaker for 12 gauge aluminum wire?
A #12 aluminium conductor with an insulation factor of 75 or 90 degrees C is rated at 15 amp. Therefore the largest size breaker to protect that wire will be a breaker rated at 15 amps.
What wire to use on 20 amp breaker?
A #12 copper conductor with an insulation factor of 90 degrees C is rated at 20 amps. A #14 conductor can not be connected to a 20 amp breaker as that conductor is only rated at 15 amps.
What size wire do I need for a 30 amp breaker?
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.
What size breaker would e needed for 10.8 amps?
In standard construction this would require a 15 amp breaker and 14 gauge copper wire.
What wire size do you need for a 125 amp panel with a 100 amp main breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
