Grounding GROUNDED OUTLET BOXES TAB FOR GROUNDING SCREW METAL SCREW GROUNDING PIN (A) ADAPTER (B) (C) Figure 1 This product is for use on a nominal 120 V or nominal 220 V circuit, and has a grounding plug that looks like the plug illustrated in sketch A in Figure 1. A temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in sketch B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in place by the metal screw. Note: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code. Page 7
