What’s the difference between PVC and Schedule 40?

Schedule 40 PVC is usually white in color and has thinner walls, thus can handle less pressure than it’s counterpart. Schedule 40 PVC pipe works best for low water pressure applications. By contrast, Schedule 80 PVC is usually gray in color and has thicker walls; therefore, it can handle higher water pressures.

Can you use plumbing PVC for electrical?

Electrical PVC is not intended to be exposed to high pressure, as in water lines, and is not rated for use with high-pressure air. … Conversely, plumbing PVC should not be used for electrical conduit applications as it does not handle ultraviolet radiation well, and is of reduced rigidity.

What is the difference between white PVC and GREY PVC?

Grey PVC is used as electrical conduit and is better suited for sunlight resistance. The fittings for this type of pipe are made to pull wires into and not intended for containing pressured fluids. White is for plumbing applications. Both use the same solvents and glues.

Can you use Schedule 40 PVC for electrical?

Rigid Nonmetallic PVC Conduit (DZYR) Schedule 40 conduit is suitable for underground use by direct burial or encasement in concrete. … So while you may be able to use schedule 40 for the entire run, you’ll have to use schedule 80 through any areas where the AHJ deems the conduit is exposed to physical damage.

What is the difference between conduit and PVC?

PVC pipe and PVC conduit have different uses. PVC pipe is used primarily in plumbing and other pressurized systems. PVC conduit is used primarily in electrical systems. PVC pipe thus is used to carry water, while PVC conduit typically works as housing for wiring.
