Sched 80 vs. sched. 40


(Thank you, Robpo -- from another thread.)

I thought sched. 80 was for better protection against possible physical abuse. How does sched 80 handle sunlight better than sched 40? Aren't they both formulated to protect against UV?

I would feel better with a piece of lead or steel pipe rather than pvc if I was going to get physically abused.

Same material, different wall thickness.
Hope your talking about gray PVC.
White is not rated for direct sunlight.

Schedule 80 offers protection to the wires and schedule 40 does not.
This is according to code.

thank you.

You know.
Protecting against physical damage. When I do a service in a driveway area, it's tough (maybe impossible) to get fittings and condulets in sch. 80 so I do it in emt.

Burns my buns as I drive around and see hundreds done in sch 40.

Thank you for letting me vent. I feel better now.

Not.

Yet 230.50 (B)(1) lists it for protection for service entrance cables where subject to physical damage.


I think I read somewhere it wasn't rated where subject to "severe" physical damage.
???
