For a 25 kW furnace, you typically need a 100 amp double-pole circuit breaker. The appropriate wire size would generally be 3 AWG copper or 1 AWG aluminum, depending on the length of the run and local electrical codes. Always consult with a licensed electrician to ensure compliance with local regulations and to confirm the specifications based on your specific installation conditions.
What else can I help you with?
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
How big of breaker do you use for 115 volt?
Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.
14 gauge wire can be on what size circuit breaker?
A 14 gauge wire is typically used on a 15 amp circuit breaker. It is not recommended to use a larger circuit breaker with a smaller wire size as this can create a fire hazard.
What size of wire and breaker do you need for a 20kw electric furnace?
In order to properly size the wire per National Electric Code (NEC) standards you will need to know the amperage and the distance of the device (heater) from the source (circuit breaker panel). In order to know the amperage one would need to know the voltage since amperage changes inversely with voltage.
What size breaker should be used for a TNIA-10 wire?
The breaker size for a TNIA-10 wire depends on the maximum current carrying capacity of the wire, which is typically indicated on the wire's packaging or in its specifications sheet. You should select a breaker that is rated slightly higher than the wire's maximum current capacity to ensure safety and avoid overloading the wire. It is recommended to consult with a qualified electrician for specific guidance on breaker sizing for your installation.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
What is the recommended wire size for a 50amp breaker?
The recommended wire size for a 50 amp breaker is typically 6-gauge wire.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
