A relocatable power tap is the code term for what most people call a power strip.
That sounds simple, but it creates a lot of jobsite confusion. People often assume a power strip is a quick fix for not having enough receptacles, when code treats it as a limited cord-connected device, not as a substitute for permanent wiring.

That is why NFPA 1 addresses relocatable power taps directly, and why electricians keep running into the same violations around offices, shops, temporary setups, and conference rooms.
What is a relocatable power tap?
A relocatable power tap is a cord-and-plug-connected device with multiple receptacle outlets that plugs into an existing receptacle.
In practical terms, it is meant to provide additional outlet access for plug-connected equipment. It is not meant to replace:
- permanent receptacles
- branch-circuit wiring
- properly planned outlet installation
- fixed wiring methods
NFPA materials also tie relocatable power taps to product listing requirements, typically UL 1363, and in some specialized uses other listing standards may apply.
Why NFPA 1 talks about power strips
The NFPA blog you pointed to frames this issue as electrical fire safety, and that is the right lens.
Power strips become a fire and shock problem when they are used outside their intended purpose. The code is not targeting normal, listed use. It is targeting the ways people misuse them, especially when a temporary convenience product starts being used like permanent infrastructure.
That is why NFPA 1 focuses on:
- listing
- direct connection
- cord routing
- damage exposure
- the difference between power strips and extension cords
What relocatable power taps are allowed to do
In normal use, a relocatable power tap can provide extra receptacle access from a permanently installed receptacle for plug-connected equipment.
Typical acceptable use looks like:
- office electronics at a desk or workstation
- temporary support for meeting-room electronics
- clustered plug loads in an indoor setting
- normal use within the device listing and rating
The important idea is that the strip is an accessory to an existing receptacle, not a replacement for needed wiring.
What relocatable power taps are not allowed to do
This is the part electricians usually need to explain to owners, tenants, and maintenance staff.
Under NFPA 1 language, relocatable power taps are not supposed to be used in ways that turn them into fixed wiring. That means they should not be:
- run through walls, ceilings, or floors
- run under doors or floor coverings
- placed where the cord is exposed to environmental or physical damage
- used as a substitute for permanent receptacles
- treated like a long-term answer to a wiring deficiency
NFPA 1 also requires relocatable power taps to be directly connected to a permanently installed receptacle, with a narrow temporary exception in certain conference or meeting room situations when approved by the AHJ.
Relocatable power taps vs extension cords
People mix these up all the time.
A relocatable power tap gives you multiple receptacle outlets from one connection point.
An extension cord gives you reach to a load farther away.
They are not the same device, and NFPA 1 treats them differently, but the safety idea behind both is similar: neither one is intended to function as permanent wiring.
Extension cords also have their own restrictions, including the rule that they are not a substitute for permanent wiring and should be used only in the limited ways allowed by code and listing.
Why the direct-connection rule matters
One of the most important NFPA 1 requirements is that relocatable power taps must be directly connected to a permanently installed receptacle.

That matters because once people start chaining devices together or using cords to create makeshift distribution systems, risk increases fast:
- more loose connections
- more overloading potential
- more damage risk
- more hidden cord routing
- more heat buildup in places nobody intended
This is why electricians should treat power-strip misuse as a real installation problem, not just a housekeeping issue.
Common mistakes electricians should watch for
Using power strips where more receptacles are needed
If the area permanently needs more plug loads, the real fix is usually additional receptacles.
Running cords under carpet or through openings
This is one of the most common violations and one of the clearest fire-damage risks.
Plugging strips into anything other than a permanently installed receptacle
That is where a lot of bad setups start.
Ignoring the listing
Not every multi-outlet device is listed for the same use. Listing matters.
Confusing power strips, extension cords, and furniture power units
They may look similar, but code and listing do not treat them the same way.
Why this topic matters for electricians
For electricians, relocatable power taps are not just an office-facility issue. They are often the visible sign that the space was never provided with enough permanent receptacles for how it is actually being used.
So when you see power strips everywhere, the real question is often not “Is this strip allowed?” but:
Why does this space need so many temporary devices in the first place?
That is the more useful electrician mindset.
Final takeaway
A relocatable power tap is a listed power strip intended for limited cord-connected use, not as a substitute for permanent wiring.
The main rules electricians should remember are:
- it must be listed
- it must connect directly to a permanently installed receptacle
- its cord cannot go through walls, ceilings, floors, under doors, or under floor coverings
- it cannot be used where the cord is likely to be damaged
- it is not the right fix for a permanent receptacle shortage
If power strips are being used like part of the building wiring system, the installation problem is usually bigger than the strip itself.
FAQ
What is a relocatable power tap?
It is the code term for a power strip or plug strip.
Are relocatable power taps allowed by code?
Yes, when they are listed and used within the limits set by code and their listing.
Can a relocatable power tap be used instead of installing more outlets?
No. It is not a substitute for permanent wiring or needed receptacle installation.
Can power strip cords run through walls or under carpet?
No. NFPA 1 prohibits that type of cord routing.
Do relocatable power taps have to plug directly into a receptacle?
Yes. NFPA 1 requires direct connection to a permanently installed receptacle, except for a narrow temporary exception in certain meeting-room situations approved by the AHJ.
