Extension Cord and Power Strip Usage

The University restricts the use of extension cords to providing temporary power for portable equipment (e.g., maintenance, cleaning, audio-visual, or construction activities).
Use of surge suppressors:

• While a surge suppressor is a power strip, not all power strips are equipped with surge suppression.
• If sensitive laboratory equipment requires the use of a surge suppressor this must be noted in the lab's standard operating procedures.
• Generally, scientific equipment must be plugged directly into primary wall outlets.

In accordance with the National Electric Code, extension cords cannot be used for the following:

• As a substitute for the fixed wiring of a structure
• Run through holes in walls, ceilings or floors
• Run through doorways, windows or similar openings
• Attached to building surfaces
• Concealed by walls, floors, or ceilings or located above suspended or dropped ceilings
• Installed in raceways, except when permitted by Code
• Where subject to physical damage

In addition, extension cords must:

• Be inspected before use
• Be removed from service if damaged
• Be certified by a nationally recognized testing laboratory (UL, CSA, ITSNA)
• Be suitable for the conditions of use and location
• Be used only in continuous lengths without splice or tap
• Not be connected in series to another cord or power strip (daisy-chain, piggy-back)
• Not to be continually connected to an outlet for more than 1 work day
• Not be used with equipment drawing more than 15 amps

Power Strips/Surge Suppressors:

• Only one strip or suppressor is allowed per duplex electrical outlet
• May not be used in series (daisy-chain, piggy-back)
• Usage limited to low current devices such as radios, computers, printers, etc.
• Not to be used with equipment containing a heating element
