I have several office tables that will be used in a classroom. The tables currently have a flexible whip that is supposed to feed into a wall outlet. Other than voiding the manufacturers warranty, is there any code violation in me taking the flexible whips off and using SO cord with a male end to plug into a receptacle?

Would I need to use a strain relief? Any input will help.

Thanks in advance.
 
110.3(B) Installation and Use.- Listed and labeled equipment shal be installed and used according to any instructions included in the listing and labeling.
 
At that point NEC is no longer involved as the tables are not fixed and simply the same as anything else you plug in like frig, vacume, blender, taoster. Only problem you might have is liability if anyone gets hurt. Now that is assuming they are not bolted down.

That is for installed equipment. This is out of NEC control unless it gets anchored. As movable and portable it has no article number

First off, this unit is listed to be hard wired ...

Second can you back that up with anything from the NEC?

Because I think I can show the NEC does apply to cord and plug connected equipment.

Here are four random examples ....

422.44 Cord-and-Plug-Connected Immersion Heaters.
Electric heaters of the cord-and-plug-connected immersion
type shall be constructed and installed so that currentcarrying
parts are effectively insulated from electrical contact
with the substance in which they are immersed.

422.45 Stands for Cord-and-Plug-Connected Appliances.
Each smoothing iron and other cord-and-plugconnected
electrically heated appliance intended to be applied
to combustible material shall be equipped with an
approved stand, which shall be permitted to be a separate
piece of equipment or a part of the appliance.

440.64 Supply Cords. Where a flexible cord is used to
supply a room air conditioner, the length of such cord shall
not exceed 3.0 m (10 ft) for a nominal, 120-volt rating or
1.8 m (6 ft) for a nominal, 208- or 240-volt rating.

440.65 Leakage-Current Detector-Interrupter (LCDI)
and Arc-Fault Circuit Interrupter (AFCI). Single-phase
cord-and-plug-connected room air conditioners shall be
provided with factory-installed LCDI or AFCI protection.
The LCDI or AFCI protection shall be an integral part of
the attachment plug or be located in the power supply cord
within 300 mm (12 in.) of the attachment plug.

.... do I need to find more?
 
How about the entire Article 605 which applies to relocatable office partitions hardwired or cord and plug connected including freestanding ones?

605.1 Scope. This article covers electrical equipment, lighting
accessories, and wiring systems used to connect, or contained
within, or installed on relocatable wired partitions.

605.8 Freestanding-Type Partitions, Cord-and-Plug-
Connected. Individual partitions of the freestanding type,
or groups of individual partitions that are electrically connected,
are mechanically contiguous, and do not exceed
9.0 m (30 ft) when assembled, shall be permitted to be
connected to the building electrical system by a single flexible
cord and plug, provided all of the conditions of
605.8(A) through (D) are met.

Most of that list is dealing with fixed equipment.
Are you saying i can not build a portable table with a cord and plug ?
article # ?
I view this table as nothing more than a power strip that is part of a table

We can't know for sure, but its possible these tables also have sinks and natural gas piped to them. Like the kind you see in science rooms. If that's the case, then I think even Jim would agree they are fixed.

Nothing in my above list is 'fixed or secured equipment'.

I never said that, although the AHJ could ask for it to be listed.

The problem is that it was built and listed to be hardwired, at that point you do not get the option to change it because of 110.3(B)

Are they to be fixed or being moved after use ?
