    1.1 These requirements cover indoor use cord and plug connected of permanently connected, furniture power distribution units (FPDU) rated 250 V AC or less and 20 Amperes or less. An FPDU may provide one or more receptacle outlets, inclusive of one current tap integral to the attachment plug, if provided, for connection of utilization equipment. An FPDU may include an integral Class 2 power supply employing integral output lead(s) and/or output connector(s) and may include receptacles with integral power supplies employing Class 2 output connector(s). FPDU’s are for fixed mounting to portable or stationary furnishings as a power supply connection for cord and plug connected electrical utilization equipment in accordance with the National Electrical Code, NFPA 70.

    1.2 In accordance with the National Electrical Code, NFPA 70, furniture power distribution units (FPDUs) shall not serve as fixed wiring of a structure or of fixed furnishings, such as but not limited to applications in permanent countertops of kitchens and bathrooms.

    1.3 A cord-and-plug-connected product as described in 1.1 with less than three receptacle outlets and provided with a Luminaire is covered under the Standard for Portable Electric Luminaires, UL 153.

    1.4 A cord-and-plug-connected product as described in 1.1 with less than three receptacle outlets and that employs an electromagnetic interference filter is covered under the Standard for Electromagnetic Interference Filters, UL 1283.

    1.5 A cord-and-plug-connected product as described in 1.1 with less than three receptacle outlets and that employs a surge protective device (SPD) is covered under the Standard for Surge Protective Devices, UL 1449, for SPD Type 3.

    1.6 A cord-and-plug-connected product as described in 1.1 that employs ground-fault protection is covered under the requirements for portable GFCIs in the Standard for Ground-Fault Circuit Interrupters, UL 943.

    1.7 This standard does not cover FPDUs intended for use with medical equipment.

    1.8 These requirements cover FPDUs provided with isolated secondary circuits.

    1.9 These requirements cover FPDUs provided with batteries located in isolated secondary circuits.

    1.10 A product that has a battery backup feature or other uninterruptible power supply equipment located in the Primary Circuit shall comply with the applicable requirements in the Standard for Uninterruptible Power Supply Equipment, UL 1778.

    1.11 A FPDU with three or more receptacle outlets may employ a Light Emitting Diode (LED) Luminaire.

    1.12 This standard contains the following Supplements:
