RMC over roadway

[ScottLund]

Does table 225.60 apply to conductors in a raceway? What is the required clearance over an industrial driveway for 480V conductors in RMC?

What is the required clearance over an industrial driveway for 480V conductors in RMC?

Are they branch circuits/feeders or service conductors?

225.60 is for systems over 600 volts and 225.18 is for systems 600 volts and less. Neither apply to conductors in a raceway or cable tray.

I would use 225.18 just to be safe, if a truck hits the RMC the conduit is probably not survive much better than open conductors.

I'm not sure how I missed the "over 600 volts" for 225.60 - thank you. I will use the 18ft height referenced in 225.18(4). I am curious since 225.18 specifies "open conductors" what an AHJ would say about clearance for a pipe bridge over a road on an industrial site used for personnel carriers and small trucks only.

Many industrial pipe bridges are less than 18' their roads. I believe the maximum height of a vechicle on a public roadway is 13'6" unless they have an "over size load" permit.

OP said this a private road, so what happens if I wanna bring this through?

That would be a design issue, not a code issue

Okay, fine- next time I launch an Apollo rocket to the moon, you ain't invited.

Well in this photo it's a traffic jam. But in real life it's a self contained miner.

It is the worlds largest earth mover and sometimes it eats D8 CATs for lunch

Cool pic. Cool link. Bookmarked it straight to my tool bar. Thanks.

Here are some of the details on the machine.
Specifications:

~ The mover stands 311 feet tall and 705 feet long.
~ It weighs over 45,500 tons
~ Cost $100 million to build
~ Took 5 years to design and manufacture
~ 5 years to assemble.
~ Requires 5 people to operate it.
~ The Bucket Wheel is over 70 feet in diameter with 20 buckets,
each of which can hold over 530 cubic feet of material.
~ A 6-foot man can stand up inside one of the buckets.
~ It moves on 12 crawlers
(each is 12 feet wide, 8' high and 46 feet long).
~ There are 8 crawlers in front and 4 in back.
~ It has a maximum speed of 1 mile in 3 hours (1/3 mile/hour).
~ It can remove over 76,455 cubic meters each day.
~It requires an external 16.6 Megawatt power supply to run

This link has some better pictures of the CAT being removed from the bucket.

If you have enough money to own that thing(or lease, use, whatever)..... Then you have enough money to remove everything and reinstall it.
