Should I use Schedule 40 or 80 Conduit?
Schedule 40 pipe has thinner walls, so it is best for applications involving relatively low water pressure. Schedule 80 pipe has thicker walls and is able to withstand higher PSI (pounds per square inch). This makes it ideal for industrial and chemical applications.
Can Schedule 40 PVC be used for electrical conduit?
Schedule 40 PVC Conduit is used in walls, floors and ceilings in accordance with NEC 352. According to NEC 352 it can also be buried directly into the earth, encased in concrete, and used in areas exposed to direct sunlight. Regular PVC Cement is too aggressive to use with ENT Flexible Conduit.
What is Schedule 80 PVC conduit used for?
Schedule 80 PVC Electrical Conduit This thicker wall structure provides more resistance to damage when installing conduits in high traffic or high hazard areas. Generally, schedule 80 PVC conduit is useable in any situation where schedule 40 conduit is applicable.
Can Schedule 80 PVC be used for electrical?
Gray Schedule 80 PVC fittings and pipe are not for electrical conduit. The fittings sold for plumbing applications do not have the required approvals for electrical applications. So even though they look similar make sure the right PVC parts are used for the right applications.
Which PVC pipe is best for electrical wiring?
Rigid Non-Metallic (PVC) Conduit – preferred for cases where wiring is run just beneath the surface of concrete walls or flooring. It’s primarily chosen because it will keep water that may seep through the wall from the wiring.
Can you use white Schedule 40 PVC for electrical?
While regular PVC and electrical conduit PVC are both made from the same type of plastic, they are not the same thing, nor should they be used for the same applications. Each should only be used as it is intended and not interchangeably.

Can I use white PVC pipe for electrical conduit?
The most noticeable difference between regular PVC and electrical PVC is the color of the pipes. PVC pipe that is used for plumbing is usually white while electrical conduit PVC is usually gray. Therefore, Schedule 80 pipes should not be used as an electrical conduit.
What are Schedule 40 fittings?
The term “schedule 40” refers to the strength and thickness of the fitting / pipe. Schedule 40 is rated at 140 degrees and varying pressure based on the fitting size. Since sch 40 fittings are rigid, their typically cemented in place using a specific type of primer and solvent.
What is Schedule 40 PVC?
PVC Schedule 40 pipe is for pressure systems where temperatures will not exceed 140° F. They are highly resilient, with high-tensile and high-impact strength. PVC Schedule 40 has better sound deadening qualities than PVC Schedule 40 DWV Foam Core and ABS Foam Core. Installation requires the use of primer and solvent cement.
What is Schedule 40?
Schedule 40 piping is a plastic pipe which is manufactured using the most common specifications for strength and thickness. It can be found in virtually any residential construction site and is used to provide plumbing and drainage for water and waste systems.
What is schedule 80 conduit?
Schedule 80 PVC conduit, length 10 ft., weight 308 per 100 ft. Schedule 80 Conduit is good for pressure applications, and has a thicker wall than Schedule 40 pipe. PVC Schedule 80 is highly durable, with high tensile and impact strength. Schedule 80 PVC pipe is used for industrial and higher pressure water flow applications.
