On June 12, 2020, a new UL Supplement was approved: Supplement SD - Furniture Power Distribution Units for

Portable (Movable) Work Space Tables. This new Supplement SD is included under UL 962A – the ANSI/UL Standard

for Furniture Power Distribution Units.

Now—products can be evaluated and listed as safe reconfigurable furniture power distribution assemblies by a Nationally

Recognized Testing Laboratory. This ensures a safe solution is available for reconfigurable portable workspace tables in

o ice areas.

Prior to June 12, 2020, no standard existed for listing this type of product. Legrand introduces the first and only code

compliant option: the ModPower System.

Legrand is excited to bring to market the first product evaluated and listed to the new UL 962A Supplement SD. Here are

some highlights of what this means and how to ensure the installation is compliant:

• The primary unit can be connected to a wall or floor outlet via a non-

detachable power supply cord.

• Additional units may be connected to the primary unit via interconnecting cords

that utilize grounding-type non-NEMA style connectors.

NEMA style plugs and receptacles, for example 5-15P, 5-15R, 5-20P and 5-20R,

may not be used as part of the interconnecting cords to ensure that units are not

plugged into a standard relocatable power tap or furniture power distribution unit.

• Legrand’s primary unit is rated 125V, 15A. Supplement SD requires that all

subordinate units be rated in compliance with Table 210.21(B)(2) which limits

the load to 80% of receptacle rating. Therefore, all subordinate units in our

system are rated 125V, 12A.

• All units, including primary, middle and end, utilize a circuit breaker. Supplement

SD requires that all furniture power distribution units for portable (movable)

workspace tables contain supplementary overcurrent protection.

This requirement was established to ensure that each unit would stop supplying

power in the event of an overload or short circuit. The required supplementary

overcurrent protection provides protection against fire and electrical injury.

• Supplement SD limits the overall length of modular assemblies to 50 feet.

The measurement is taken from the outside surface of the last unit to the face of

the plug on the primary unit’s non-detachable power supply cord. Legrand has

evaluated and listed our system to allow for the connection of (6) total units with a

maximum length of 48.5 feet.

CODE MARKINGS

Supplement SD requires additional product markings to ensure that the product is installed and utilized in a safe manner.

• The cord tag contains the following text:

CAUTION: To Reduce the Risk of Shock or Fire – Use Only with LEGRAND’S FURNITURE POWER DISTRIBUTION

UNIT (FPDU) for Movable Work Space Table Modules Only.

This requirement was adopted to prevent users from inadvertently connecting Legrand’s product to that of another

manufacturer. UL has only evaluated the safety and reliability of Legrand’s complete assembly of furniture power

distribution units for portable (movable) workspace tables.

• Supplement SD requires that the following warning be included on the cord tag of male interconnecting cords:

WARNING: Risk of Fire - The overall length of an extendable FPDU for a movable work space table including the

power supply cord, all enclosures and all interconnecting cords shall not exceed ___ft ( ___m).

NOTE: This warning is to be proceeded by the symbol

• Supplement SD requires the following Caution text that may be on the cord tag or within the installation instructions:

CAUTION: Risk of Electric Shock. Do not plug into another relocatable power tap, an FPDU or an extension cord.

Legrand recognizes the importance of this caution text in preventing fires and has placed this marking on the cord tag

near the plug on the non-detachable power cord.
