Default Getting power to tables in warehouse

So I have a bit of a unique situation. A good customer of mine failed a fire inspection because they are using extension cords to get power to 3 tables and 1 desk. These tables and desk are about 5'-10' away from the nearest wall. The cords all come out of 1 20A outlet box, the power is used for very basic things such as a couple scales and a computer. The fire inspector doesn't want any extension cords used.

The customer is in a leased warehouse and they have plans to move next year when the lease is up, so they don't want to spend any more than they absolutely have to on this one thing, since it's only to pass the fire inspection anyway.

Dropping power down from the 40' ceiling could be a pain and more expensive than they are looking for. So I am looking for some type of on-floor solution. Maybe those rubber mats that have the hole for wiring?

Suggestions?

What do they use the floor for, assembly? Do pallet jacks, pushcarts or forklifts need to go through the area?

I have used this a few times in office areas, but never in a warehouse facility. I would be worried about damage in a warehouse where more than high heels and a vacuum might attack it.

Good question. The floor between the tables is just for walking, no pallet jacks or anything like that. They have the cords taped down right now and I noticed that they were in really good shape and hadn't been rolled over.

Then either of the two covers suggested here would work out fine.

Mention to them they can also reuse the covers anywhere they move.

If you want something ON the floor, I like wiremold 1500. It is easy to work with. Some feel it is too much of a trip hazard, I feel like it's not really different from the threshold on a doorway.

Run conduit and cover it with a yellow ramp. Pretty standard solution for industry.

The Wiremold doesn't seem warehouseish enough. I like the idea of running 1/2" EMT on the floor, but I need to find the proper protection for it that the fire inspector won't call a trip hazard.

String an aircraft cable from wall to wall over the desks and support cord drops from it?

The proper warehouseish thing to do is just hide the benches behind pallets stacked hiqh with boxes until the inspector leaves, then tape the extension cords to the wall, the floor, the table, and the equipment with about a six layers of packing tape.

From the ceiling run SO cord and a strain relief

Or

Rigid conduit to single gang threaded malleable iron box with nipple to floor with floor flange securing it to floor.

I'm sure they don't want to spend much money, but them being able to remain open for business will make it easier to pay their bill.

This really shouldn't be that expensive, the cost is going to be a 40' scissors lift. A 40' ceiling is a real PITA.

I exaggerated the height of the ceiling because I really don't know what it is, but it seems higher than usually, at least 30'. But they have large forklifts and a man-cage that I could use to do the work, so no scissor lift needed.

If I could run 1/2" EMT on the floor and properly protect it and make it safe from tripping, it would be easier than running pipe all the way up to the trusses and then having drops.

I am not a fan of the fork lift cages because they never volunteer their best driver to run you around, in fact they usually give you their least useful. Bring one of those DIY breathalyzers and make him sober up before you strap in.

Well what do you feel makes it safe from tripping? If it's on the floor, you can have a little bump (pancake raceway) or a big bump (ramp over conduit) but that's about it.

The only other options are under the floor or overhead. After that the only dimension left to move in is time. You could rent a time machine and do it in 1915 when nobody cared about safety, but I imagine that will cost more to rent than the scissors lift.

Im not understanding why you would have to run all the way up. If there's no tow motor traffic behind the desks just bridge over from the wall.

Thanks to a co-worker explaining this to me, we now absolutely refuse to go up on a fork truck basket unless it's one of us driving it. No way no how do I trust my life to someone I don't even know.

Would still need hangers coming down off the trusses / framing.
