What material is used for insulation on the outside of connecting wires?

Cross link polyvinyl chloride RW90 (PVC) and THHN are two common types of insulation THHN wire stands for thermoplastic high heat resistant nylon coated wire. THWN stands for thermoplastic heat- and moisture resistant nylon coated wire.


What size of conduit you need for 3 phase 8 thwn wire?

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.

What size conduit for a 240 volt 50 amp wire?

For a 240 volt, 50 amp circuit, you typically use a minimum of 3/4 inch conduit for copper wire and 1 inch conduit for aluminum wire, assuming you are using THHN or THWN wire. The specific size may vary based on the number of conductors and any bends in the conduit. Always consult local electrical codes and the National Electrical Code (NEC) for precise requirements and adjustments based on your specific installation conditions.
