Steve, I can not see how 400.7(A)(6) will help you at all for your proposed installation.
Take a look at 400.7(B) and notice that it requires an attachment plug used with flexible cords used as allowed by 400.7(A)(3), (A)(6) and (A)(8)
And when we run into technicalities like a power strip vs a surge supressor.
In all likelihood if you look at the UL tag on this device you will see "Relocatable Power Tap"
Here is the UL white book info for ‘‘Relocatable Power Tap,’’ ‘‘Power Tap’’ or ‘‘Outlet Strip.’’
RELOCATABLE POWER TAPS (XBYS)
USE AND INSTALLATION
This category covers relocatable power taps rated 250 V ac or less, 20 A or
less. They are intended for indoor use as relocatable multiple outlet extensions
of a single branch circuit to supply laboratory equipment, home workshops,
home movie lighting controls, musical instrumentation, and to provide
outlet receptacles for computers, audio and video equipment, and
other equipment. They consist of one attachment plug and a single length of
flexible cord terminated in a single enclosure in which one or more receptacles
are mounted. They may, in addition, be provided with fuses or other
supplementary overcurrent protection, switches, suppression components
and/or indicator lights in any combination, or connections for cable, communications,
telephone and/or antenna.
Relocatable power taps are intended to be directly connected to a permanently
installed branch circuit receptacle. Relocatable power taps are not
intended to be series connected (daisy chained) to other relocatable power
taps or to extension cords.
Relocatable power taps are not intended for use at construction sites and
similar locations.
Relocatable power taps are not intended to be permanently secured to
building structures, tables, work benches or similar structures, nor are they
intended to be used as a substitute for fixed wiring. The cords of relocatable
power taps are not intended to be routed through walls, windows, ceilings,
floors or similar openings.
Relocatable power taps have not been investigated and are not intended
for use with general patient care areas or critical patient care areas of health
care facilities as defined in Article 517 of ANSI/NFPA 70, ‘‘National Electrical
Code’’ (NEC).
Component power taps may be factory installed on relocatable equipment
intended for use in general patient care areas or critical patient care areas as
defined in the NEC. They are intended to comply with 60601-1, ‘‘Medical
Electrical Equipment, Part 1: General Requirements,’’ and 60601-1-1, ‘‘Safety
Requirements for Medical Electrical Systems.’’ Refer to Medical Equipment
(PIDF).
