Feeder Height

[Mike Lamb]

This threaded conduit feeds a garage and is about 8' off the ground. Is there a height requirement?

I'm not anywhere near my code books so I might be missing something, but I can't recall any rule that would apply to the height of a feeder inside RMC. I'm pretty sure that the clearance requirements in article 230 apply only to service conductors, not feeders.

The only issue I can see is that the conduit isn't fastened within 3' of the junction box (or conduit body, or whatever it is) on the garage.

I'll be back in my office sometime Thursday. If I find a restriction, I'll let you know.

Is that NM coming through the cornice under the box?! I usually see a set up like that run along the ground or under the stair nosing. It must have taken Joe Homeowner all weekend to do that, bet he's real proud of himself.

No. The raceway in the garage to that j-box was MC or AC. I can't tell the difference.

This is probably a common sense thing with the ht. If it seems too low, it probably is. 8' isn't too bad if it is soundly secured in pipe. My looks in the NEC and IRC also show hts. only for service which is usually open conductors.

In my original report, I flagged it as wrong because this was a new one for me. I have seen extension cord feeders for garages lower than 8'. I did note that an underground feed is best.

Yes, but those are service requirements from the utility company. They don't apply to feeders, only services.

Also,

Most of the utility providers have published their own set of instructions so that document might not work for everyone. Everyone should go to their local providers' websites', find the provider' manuals and rules and download them.

Would have made more sense for the guy to run the conduit under those deck steps and into the garage.

Try 225.60

Hi Jim,

I believe that section only applies to conductors that are over 600 volts.

225.22 says that raceways in wet locations shall be arranged to drain, which this circuit obviously is not. Also, if the pipe contains a feeder circuit or a branch circuit, there must be a disconnecting means near the point of entrance. Feeder circuits also require grounding to earth.
