Schedule 80 pvc electrical conduit differs from schedule 40 conduit in one way.
Schedule 40 will have thinner walls than schedule 80 for the specified pipe size. By contrast, schedule 80 pvc is usually gray in color and has thicker walls; These maximum working pressure figures rely on the fact that your pvc products will be used in a location providing optimal temperature year round. Schedule 80 pipe has thicker walls and is able to withstand higher psi (pounds per square inch).
I am feeding some 30 amp washer dryer plugs from a disconnect with about 24 to grade of exposed 3/4 pvc conduit(conduit is ran underground from the disco).
The scheduling system came into the picture as a standard of measuring as there was a need to have a universal system for referring to pvc. Schedule 40 pvc pipe works best for low water pressure applications. Therefore, it can handle higher water pressures. In pvc fittings, it is the outside diameter that changes.

For both pipe and fittings schedule 80 has a greater wall thickness than schedule 40. To give you an idea of the size difference, 1” schedule 40 pvc pipe has a.133” minimum wall and 450 psi, while schedule 80 has a.179” minimum wall and 630 psi. However, it is more suitable for cold water as hot water can crack the pipe. Pvc in schedules 40 and 80 is used worldwide.
I also think the schedule 40 is fine.

Generally, schedule 80 pvc conduit is useable in any situation where schedule 40 conduit is.
Also due to its thicker walls, schedule 80 pvc isn’t only faster than schedule 40 pvc in handling psi, but is also more resistant to bending. This thicker wall structure provides more resistance to damage when installing conduits in high traffic or high hazard areas. Schedule 40 does not have a lower temperature limitation since it is not allowed to be used in areas where subject to physical damage. Its all in the nec article 352.
Schedule 80 pvc pipe comes in a thicker and stronger design which makes it able to handle high pressure.
It is worth noting, however, that additives during the manufacturing process can produce differently colored pipes. You might have noticed, the outside diameter of both schedule 40 and 80 pipes are the same, but 80 pipe has thicker walls; Thus, schedule 80 pipes are a bit more expensive than their 40 counterparts. As the temperature of the pvc increases the pressure that the pvc can.
24 rows because of the difference in sizes, schedule 40 pvc pipes and fittings will have.
Both schedule 40 and 80 fittings have the same inside diameter. Comparing schedule 40 and schedule 80. Schedule 80 comes in dark gray color generally and schedule 40 comes in white color. It often makes shipping more expensive and more arduous to handle when installing large pipes and fittings.
Sch 80 is generally only required where the wire is subject to damage like vehicle traffic.
Schedule 80 pvc conduit is listed Schedule 80 pvc pipes have thicker walls than schedule 40 pvc pipes (of the same outside diameter) and are therefore stronger and able to handle more pressure. Most supply houses don't even stock schedule 80 pvc conduit. A small hit with a flowerbed shovel is not that big of deal for sch 40 pipe.
Because schedule 80 pvc has thicker walls, it is heavier than schedule 40 equivalent pipes and fittings.
Due to its thinner walls, the schedule 40 pipe is best suited for conditions with low water pressure. This makes it ideal for industrial and chemical applications. You can use schedule 40 or 80 underground or outside, and sometimes even inside. Schedule 80 pvc conduit underground electic (electrical) 24 may 10 00:03 the idea of a weep hole, or vault (manhole) to drain water from a conduit system, is to relieve hydrostatic pressure that could develop in a large system with changes in grade.
