What size PVC conduit would be required to carry five runs of number 12 AWG conductors?

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.


How many 10 awg thhn wire can fit in half inch emt?

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.

How many Amps is number 4 THHN copper rated for?

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.


What is the appropriate wire size for a 125 amp circuit using THHN wire?

For a 125 amp circuit using THHN wire, the appropriate wire size would be 1/0 AWG.


What is the recommended wire size for a 100 amp circuit using THHN wire?

The recommended wire size for a 100 amp circuit using THHN wire is typically 3 AWG (American Wire Gauge).


Five 8 aluminum conductors with THHN insulation are to be routed through a conduit found in a boiler room with an ambient temperature of 75 degree C. What would be the ampacity of each conductor?

#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.


What size conduit for 200 amp service?

50 mm or 2 inch will handle the 3/0 wires for a 200 amp service.


How many 12 thhn conductors are allowed in three quarter inch emt?

In a three-quarter inch EMT (Electrical Metallic Tubing), the maximum number of 12 AWG THHN conductors allowed is typically 10, according to the National Electrical Code (NEC) guidelines for conduit fill. However, this number can vary based on factors such as the specific application, bundling, and ambient temperature. It’s always important to consult the current NEC code and local regulations for accurate requirements.


Splice 5 12 AWG wires into 1 4 AWG wire?

No, code does not allow that.


What size of copper wire can carry 30 amps?

Couple of things wrong here. 30 isn't a wire size. If you mean a wire that can carry 30 amps that would be # 10. Now it depends on how many # 10 wires you want to put into a conduit that governs the size of the conduit.


Can a 8 awg wire be replaced by 2 10 awg wires?

No, a single 8 AWG wire cannot be replaced by two 10 AWG wires in terms of electrical capacity and current-carrying capability. The 8 AWG wire has a larger cross-sectional area and can handle more current compared to two 10 AWG wires combined. It's important to match the wire gauge with the specific requirements of the circuit to ensure safety and proper functioning.
