Depends on location and local codes.
typically plastic conduit or PVC is used outside or in wet locations. There are restrictions for PVC conduit. PVC can also be buried at a minimum depth of 24"
There are a few types of metal conduit. EMT is used the majority of the time. The rigid pipe threads together and can be used in just about all locations.
Then there is pvc coated rigid pipe which can be used anywhere provided you use the proper fittings.
There are other types of conduit, such as fiberglass, aluminum and composites.
What else can I help you with?
What size rigid metal conduit should be used to house eight no 6 rh wires AND NINE NO 14 FEP wires?
For the eight No. 6 THHN wires and nine No. 14 FEP wires, a 1 ½ inch rigid metal conduit would be suitable to accommodate the wires while providing ample space for installation and allowing for easy cable pulling. This size conduit allows for proper bundling and prevents overheating of the wires.
Can regular PVC glue be used on electrical conduit?
No, regular PVC glue should not be used on electrical conduit. It's important to use a solvent specifically designed for electrical conduit to ensure a secure and safe connection. Using the wrong type of glue can compromise the integrity of the conduit and pose a safety hazard.
Is it permitted to use flexible conduit over 6 feet in length as a grounding means?
No. The new electrical code change does not allow any flexible conduit to be used as a ground means. It is now required to have a green ground wire pulled into the conduit with the other conductors in the flexible conduit. This grounded bonding conductor is not counted as wire fill when calculating the size of the flexible conduit to use
What must be attached to the top end of a conduit riser where conduit is used in a service?
A service head or LB fitting must be attached to the top end of a conduit riser where conduit is used in a service. This provides a termination point for the conduit and allows for easy access to the conductors inside the conduit.
Explain wire size as opposed to gauge size?
Wire size refers to the physical dimensions of a wire, usually expressed in millimeters or inches. Gauge size, on the other hand, is a measurement of the wire's diameter based on a specific gauge system (such as AWG or SWG). So, while wire size refers to the actual physical dimensions, gauge size is a standardized measurement used for electrical wiring.
What information can I find in the conduit size chart for wire?
A conduit size chart for wire provides information on the recommended conduit size based on the wire gauge and the number of wires being used. It helps in determining the appropriate conduit size for safe and efficient wire installation.
What size conduit should be used for accommodating 4/3 wire?
For accommodating 4/3 wire, a 1-inch conduit size should be used.
What size conduit should be used for 10/2 wire?
For 10/2 wire, a 3/4 inch conduit should be used.
What size conduit should be used for 12/2 wire?
For 12/2 wire, a 1/2 inch conduit should be used.
What size conduit should be used for accommodating 8/3 wire?
For accommodating 8/3 wire, a 1-inch conduit should be used.
What size conduit should be used for accommodating 6/3 wire?
For accommodating 6/3 wire, a 1-inch conduit should be used.
What is the smallest size emt conduit that can be used with nineteen 10 gauge thwn wires?
1 1/2 inch
What information can be found in the conduit wire chart?
A conduit wire chart provides information on the types and sizes of wires that can be used in different conduit systems. It includes details such as wire gauge, insulation type, and maximum current capacity for each wire size.
What is the appropriate NEC conduit size for the electrical wiring in this project?
The appropriate NEC conduit size for the electrical wiring in this project should be determined based on the number and size of the conductors being used, as well as the specific requirements of the project. It is recommended to consult the NEC guidelines and work with a qualified electrician to determine the correct conduit size for the wiring.
What information does the conduit wire fill chart provide for determining the appropriate amount of wiring that can be safely installed in a conduit?
The conduit wire fill chart provides information on the maximum number and size of wires that can be safely installed in a conduit based on the conduit's size and type of wires being used.
What information does the NEC conduit fill chart provide for determining the appropriate size of conduit for electrical wiring installations?
The NEC conduit fill chart provides information on the maximum number and size of electrical wires that can be safely installed in a conduit based on the conduit size and type of wires being used. This helps determine the appropriate size of conduit needed for specific electrical wiring installations to ensure safety and compliance with regulations.
What size Romex should be used for a 20 amp circuit?
For a 20 amp circuit, 12-gauge Romex should be used.
