2. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than 150
volts:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine will have
a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like the adapter illustrated in Fig.
B, may be used to connect this plug to a matching 2-conductor receptacle as shown in Fig. 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. Whenever the adapter is used, it must be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.
WARNING:
SHOCK HAZARD. IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY
