This electric equipment is for use on a
nominal 120 volt circuit, and has a
grounded plug that looks like the plug
illustrated in (Fig A). A temporary adaptor that looks like the adaptor illustrated in (Fig B & C) may be used to connect this plug to a 2-pole receptacle as
shown in (Fig B) if a properly grounded
outlet is not available.
The temporary adaptor should be
used only until a properly grounded
outlet (Fig A) can be installed by a
qualified electrician.The green color
rigid ear, lug or the like extending from
the adaptor must be connected to a
permanent ground such as a properly
grounded outlet box cover. Whenever
the adaptor is used, it must be held in
place by a metal screw.
Note: In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code.
