What type of pipe

[Mookers]

Im installing 2 200 amp sub panels on the fourth floor of school, main is in basement. What kind of piping can i use outside of building? Im using 2"rigid EMT to start up building at ground level to avoid it being crushed by traffic, What is legal to continue up building and is not that heavy as rigid steel and can keep the continius ground?

Your teminology is not correct.

You're using 2" rigid conduit, and you can switch over to 2" EMT.

IMC is lighter than Rigid

IMC is lighter than Rigid

EMT is lighter than IMC

I'd probably do IMC starting at the MDP up to and including the first stick above ground, then switch to PVC.

EMT is lighter than IMC

depending on what part of the country you live in, EMT may not hold up to the elements, IMC is just another option:wink:

Lest ye forgeteth, there is such a thing as Aluminum conduit. This is surprisingly light.
How come nobody ever mentions Fiberglass conduit? I got an intirguing catalogue from Champion Fiberglass and they say you can drive a truck over it. Of course it's not conductive but what's the matter with an EGC anyway?

Have used a lot of fiberglass strut in computer areas.

Wonder if fiberglass is sunlight resistant?
