Can you mix Schedule 40 and 80 conduit?
Sizing & Diameter
This means schedule 40 and 80 pipe do fit together and can be used together if necessary. The only thing to be careful of is that the lower pressure handling schedule 40 parts meet the pressure requirements of your application.
What is the difference between Schedule 40 and Schedule 80 PVC conduit?
The difference is in the inside diameter or I.D. of the pipe. Schedule 80 PVC pipe will have a smaller inside area than Schedule 40 pipe because of its thicker wall. For that reason, flow is more restricted in Schedule 80 pipe vs Schedule 40 of the same size. The same is true of PVC fittings in both schedules.
What is the difference between Schedule 40 and Schedule 80?
The major difference between schedule 40 and schedule 80 pipe is the wall thickness, inside diameter, and their weight. Schedule 80 will have a greater wall thickness, a smaller inside diameter and a higher weight than Schedule 40 pipe at a given nominal pipe size.

Can you run multiple circuits in one conduit?
Feed separate circuits through the same conduit. You can do this, just make sure your conduit is large enough to hold the wires easily. The major downside here is that, while it only requires another conduit run, it also requires you to home run three circuits to your house.
Is a neutral a current carrying conductor?
The grounded neutral conductor is considered a current-carrying conductor, but only under the conditions specified in 310.15(B)(4). Equipment grounding (bonding) conductors are never considered current carrying, but they are not designed to be used for this purpose [310.15(B)(5)].
Why do I have voltage between neutral and ground?
Neutral-to-earth voltage can be caused by a number of factors, both in and around the farm. The amounts of minerals and moisture in the soil, subsoil and rock strata, and the varying water table level can affect any grounding system and change N-E voltages.
Is ground wire considered a conductor?
It is most correctly referred to as a “grounded neutral conductor,” but most times referred to as “the neutral” or “the ground wire”. Since the neutral or grounded wire is a necessary part of the electrical path, grounded wires carry electrical current under normal operating conditions.
