electrical wiring to shed


I have 100 feet of 10/3 NMWU wire... I have some flex piping left over from another job. Can I put the wire through the piping in sections? The piping is in 10 foot lengths. With the flexable piping I wouldnt be able to fish the wire through anyways... It is just for extra protection. Or will water/ice getting into the piping ruin the wire?

Or should I just direct bury?

You can bury it if you don't connect it to any power, it's NW wire.

Southwire's CU-NMWU cables may be used in underground installations, including direct burial, at conductor temperatures not exceeding 60C. Southwire Type NMWU also may be used for work in both concealed and exposed areas to the weather in dry and wet locations. The minimum recommended installation temperature is minus 40 C for two-conductor cables - sizes AWG 14 through AWG 6 - and minus 25C for all other sizes. For three-conductor cables the minimum recommended installation temperature is minus 10 C. Material should be properly stored above 0C for 24 hours prior to installation. The maximum voltage rating for all intended applications is 300 volts. Consult the Canadian Electrical Code 1 for further information related to applications.

I've never heard of it before. Is this a Canadian spec'd wire?

Yes, this wire is underground wire in Canada. Direct burial etc.

Thoughts on my original post?

I hate to even hazard a guess. I don't know much about the Canadian code.


Now, down here, if you complied with conduit fill requirements and it was an acceptable type of wire, I don't see why you couldn't.

Why do you believe you wouldn't be able to pull the wire through the conduit. That generally is only because the conduit is too small or there are too many bends in it. Other than that, it can generally be overcome.
