According to appendix C of the NEC, 3 #2 awg are permitted in a 1" EMT.
You will need to look up cabling/wiring codes.Is it:Telephony,Audio distribution,110 volt power lines, orHigher voltage power lines?
A size 3/0 AWG copper main bonding jumper is typically required for service entrance conductors rated at 250 kcmil copper. This is based on NEC requirements for sizing the main bonding jumper to be at least 1/10th the circular mil area of the largest service entrance conductor.
Copper wire is commonly used in electrical wiring for buildings, homes, and industrial facilities. It is also used in telecommunications and data networking applications for transmitting signals. Additionally, copper wire is used in various consumer electronics and appliances.
For five runs of #12 AWG conductors, a minimum of 1 inch PVC conduit would be required to meet the fill ratio requirements, providing adequate space for the conductors while allowing for future additions or modifications.
For AWG 8 wire, the recommended conduit size typically depends on the number of conductors and the type of conduit used. For a standard installation with a single AWG 8 copper wire, a 1/2-inch conduit is generally sufficient. However, if multiple wires are present or if the conduit is of a different type (like PVC or EMT), it may be necessary to use a larger conduit, such as 3/4-inch. Always refer to local electrical codes and guidelines for specific requirements.
9-10, but the conduit may not exceed a certain length, or a certain voltage in order for you to "legally" do it. Many applications allow for conduit fill ratio's that exceed the standards of the NEC ( National Electrical Code) and most of them are short (less than 24") "chases" between control devices mounted in listed Junction boxes for that purpose. It is not advisable to fill a conduit more than the NEC allows for purposes of heat dissipation.
The ampacity of 12 AWG THHN wire is typically around 30 amps for general applications when used in a conduit at a temperature rating of 60°C (140°F). However, if the wire is used in a different environment or at higher temperatures, the ampacity may be lower. Always consult the National Electrical Code (NEC) or local regulations for specific applications and conditions to ensure safety and compliance.

To determine the appropriate conduit size for three-phase 8 AWG THWN wire, you need to consider the number of conductors and the type of conduit. Typically, for three conductors, you would use a conduit fill chart that accounts for the conduit type and the number of wires. For EMT (Electrical Metallic Tubing), a 1-inch conduit is usually sufficient for three 8 AWG THWN wires, but it's essential to verify with local codes and regulations. Always consult the NEC (National Electrical Code) for specific requirements.
According to the National Electrical Code (NEC), the ampacity of a 4 AWG THHN copper wire at 75°C is 85 amps, and 95 amps at 90°C.
The maximum number of 14 AWG wires allowed in a half-inch conduit depends on the type of conduit and local electrical codes. According to the National Electrical Code (NEC), for a standard half-inch EMT conduit, you can typically fit up to 9 conductors. However, it's important to check the specific NEC tables and local regulations, as factors like insulation type and conduit fill rules can affect the final count. Always consult a qualified electrician for precise calculations.
For a 125 amp circuit using THHN wire, the appropriate wire size would be 1/0 AWG.
Yes, you can use 10 AWG (American Wire Gauge) wire in a half-inch conduit, provided that the conduit is not overfilled according to the National Electrical Code (NEC) guidelines. Generally, a half-inch conduit can accommodate several 10 AWG wires, but it's important to check the specific fill capacity based on the number of conductors and any additional requirements for bends or fittings. Always ensure that the installation adheres to local codes and regulations for safety and compliance.
#8 aluminum thhn 90 degree wire is rated at 30 amps. Remember to de-rate the wire for more that three conductors in a raceway and the second de-rate for the ambient temperature. Most students miss the de-rate for more that three conductors in a raceway.
The recommended wire size for a 100 amp circuit using THHN wire is typically 3 AWG (American Wire Gauge).
