Need Help Choosing Conduit for 6/3 Wire

Charging and Infrastructure
1

I’m working on an electrical project and I’m trying to figure out the best conduit to use for 6/3 wire. I want to ensure everything complies with local electrical codes and works safely in my installation.

Here are my questions:

  • What type of conduit works best with 6/3 wire?
  • Are there any specific sizing guidelines I should follow?
  • Does it make a difference if I’m using it for EV charging in a garage versus other installations?

I’ve seen some discussions about EMT, PVC, and other materials, but I’m not clear on which would be most appropriate for my needs. Any advice or personal experiences you can share would be greatly appreciated! Thanks in advance for your help!

I’ve used PVC conduit for 6/3 wire in outdoor installations. It’s lightweight, easy to work with, and doesn’t corrode. Just make sure it’s buried deep enough if it’s underground!

That’s good to know! I was considering EMT for my garage, but I’ve heard it can rust. Any tips on keeping it durable?

EMT does have that rust issue, but if it’s in a dry area, it can work well. Just make sure to use corrosion-resistant fittings to keep things safe.

Thanks for the tip! What about flexible conduit? Is it a good choice for tighter spaces?

6

Flexible conduit is great for tight spaces! It’s easier to install in tricky spots. Just ensure it’s rated for the wire size; some can be quite restricting.

7

How about the cost? Are there significant price differences between PVC, EMT, and flexible conduits?

8

In general, PVC is usually the cheapest, followed by flexible conduit. EMT tends to be a bit pricier due to its metal construction, but it lasts longer in some conditions.

Interesting! I also heard that EMT requires grounding. Is that true?

10

Yes, EMT must be grounded to meet electrical code standards. It’s essential for safety, especially in damp or wet locations.

11

I find installation ease really depends on the environment. I struggled with EMT in a cramped attic space—wouldn’t recommend it there!

I can relate! Flex conduit might be better in those tight spots. Anyone have installation horror stories?

13

I’ve had a few installation fails! Tripped while pulling wire through PVC and came out covered in dirt. It’s a tough job!

14

We’ve all been there, briandavis! Just remember—safety first. Always ask a friend for help when dealing with heavy conduit!

15

What about temperature differences? Could that impact conduit choice?

16

Yes, extreme temperatures can affect durability. PVC can become brittle in the cold, while flexible conduits can lose shape. Always check the ratings.

When choosing conduit for 6/3 wire, it’s crucial to select the right type that provides adequate space for bending and cooling. PVC or EMT are popular choices. Make sure to follow local codes for installation!

18

Absolutely! You should also consider the length of the run to avoid derating the wire. It’s important for safety.

19

Don’t forget to include necessary fittings for your conduit! Elbows and couplings will help manage your bends without straining the wire. Check the manufacturer’s guidelines for bend radii.

Great point! I always use a fish tape to pull the wire through to prevent any kinking. It makes a world of difference.
