There are no specific regulations governing power strips; however, OSHA does address this issue in a November 18, 2002 Letter of Interpretation which says:
“OSHA’s standard at 1910.303(b)(2), “Installation and Use,” requires that “Listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling.” Manufacturers and nationally recognized testing laboratories determine the proper uses for power strips. For example, the UL Directory contains instructions that require UL-listed RPTs to be directly connected to a permanently installed branch circuit receptacle; they are not to be series-connected to other RPTs or connected to extension cords. UL also specifies that RPTs are not intended for use at construction sites and similar locations. “Power strips are designed for use with a number of low-powered loads, such as computers, peripherals, or audio/video components. Power loads are addressed by 1910.304(b)(2), Outlet devices: “Outlet devices shall have an ampere rating not less than the load to be served.” Power strips are not designed for high power loads such as space heaters, refrigerators and microwave ovens, which can easily exceed the recommended ampere ratings on many power strips. They must also meet the requirements of 1910.305(g)(1), Use of flexible cords and cables. For example, the flexible power cord is not to be routed through walls, windows, ceilings, floors, or similar openings.”
